HELLO,DID YOU REMEMBER ME?I AM TINGU.I THINK THAT YOU FORGOT ME. I’M GIVING YOU SOME DATA ABOUT IMPORTANCE OF LIGHT IN PHOTOSYNTHESIS HELLO Importance of Light in Photosynthesis

9 Importance of Light in Photosynthesis from EBEE’S
Light is a factor required in order that photosynthesis can occur. In any series of chemical reactions where one substance combines with another to form a larger compound, energy is needed to fuel the reactions. Energy for photosynthesis is provided by light from the sun or from artificial lamps. As with carbon dioxide, the amount of light energy present is important in determining the rate of photosynthesis - simply, the more light or greater illuminance (intensity) absorbed by the plant, the more photosynthesis can take place. Light energy is measured in joules per square metre, but for practical purposes the light for plant growth is measured according to the light falling on a given area, i.e. lumens per square metre (lux). Radiant energy (irradiance) is a less useful method of measurement because it includes a significant quantity of energy from wavelengths that do not contribute to photosynthesis. However, photosynthetically active radiation (PAR) is the most useful method as it is the energy that can be used for photosynthesis (units _W/m2).Whilst the measurement of illuminance is a very useful tool for the grower, it is difficult to state the plant's precise requirements, as variation occurs with species, age, temperature, carbon dioxide levels, nutrient supply and health of the plant. However, it is possible to suggest approximate limits within which photosynthesis will take place; a minimum intensity of about lux enables the plant's photosynthesis rate to keep pace with respiration, and thus maintain itself.The maximum amount of light many plants can usefully absorb is approximately lux, while good growth in many plants will occur at lux. Plant species adapted to shade conditions, however, e.g. Ficus benjamina, require only 1000 lux. Other shade-tolerant plants include Taxus spp., Mahonia and Hedera In summer, light intensity can reach lux and is therefore not limiting, but in winter months, between November and February, the low natural light intensity of about lux is the limiting factor for plants actively growing in a heated greenhouse or polythene tunnel. Care must be taken to maintain clean glass or polythene, and to avoid condensation that restricts light transmission. Intensity can be increased by using artificial lighting, which can also extend the length of day, which is short during the winter, by supplementary lighting.This method is used for plants such as lettuce, bedding plants and brassica seedlings. Total replacement lighting. Growing rooms which receive no natural sunlight at all use controlled temperatures, humidities and carbon dioxide levels, as well as light.Young plants which can be grown in a relatively small area, and which are capable of responding well to good growing conditions in terms of growth rate, are often raised in a growing room. The type of lamp. Lamps are chosen for increasing intensity, and therefore more photosynthesis. All such lamps must have a relatively high efficiency of conversion of electricity to light, and only the gas discharge lamps are able to do this. Light is produced when an electric arc is formed across the gas filament enclosed under pressure inside an inner tube. Light, like other forms of energy, e.g. heat, X-rays and radio waves, travels in the form of waves, and the distance between one wave peak and the next is termed as the wavelength. Light wavelengths are measured in nanometres (nm); 1nm _ one thousandth of a micrometre. Visible light wavelengths vary from 800 nm (red light - in the long wavelength area) to 350 nm (blue light -in the short wavelength area), and a combination of different wavelengths (colours) appears as white light. Each type of lamp produces a characteristic wavelength range and, just as different coloured substances absorb and reflect varying colours of light, so a plant absorbs and reflects specific wavelengths of light. Since the photosynthetic green pigment chlorophyll absorbs mainly red and blue light and reflects more of the yellow and green part of the spectrum, it is important that the lamps used produce a balanced wavelength spectrum to include as high a proportion of those colours as possible, in order that the plant makes most efficient use of the light provided. The gas included in a lamp determines its light characteristics. The two most commonly used gases for horticultural lighting are mercury vapour, producing a green blue light with no red, and sodium, producing yellow light. This limited spectrum may be modified by the inclusion of fluorescent materials in the inner tube, which allow the tube to re-emit wavelengths more useful to the plant emitted by the gas and re-emit the energy as a shorter wavelength. Thus, modified mercury lamps produce the desirable red light missing from the basic emission. Low-pressure mercury-filled tubes produce diffuse light and, when suitably grouped in banks, provide uniform light close to plants. These are especially useful in a growing room, provided that they produce a broad spectrum of light as is seen in the ‘full spectrum fluorescent tubes'. Gas enclosed at high pressure in a second inner tube produces a small, high intensity source of light. These small lamps do not greatly obstruct natural light entering a greenhouse and, while producing valuable uniform supplementary illumination at a distance, cause no leaf scorch. Probably the most useful lamp for supplementary lighting in a greenhouse is a high-pressure sodium lamp, which produces a high intensity of light, and is relatively efficient (27 per cent). Carbon dioxide enrichment should be matched to artificial lighting in order to produce the greatest growth rate and most efficient use of both factors.

GO AHEAD See next page

11 BEAUTIFUL FLOWERS

12 Tropical Rain Forests These forests are restricted to heavy rainfall areas of the Western Ghats and the island groups of Lakshadweep, Andaman and Nicobar, upper parts of Assam and Tamil Nadu coast. They are at their best in areas having more than 200 cm of rainfall with a short dry season. The trees reach great heights up to 60 metres or even above. Since the region is warm and wet throughout the year, it has a luxuriant vegetation of all kinds – trees, shrubs, and creepers giving it a multilayered structure. These forests appear green all the year round. Some of the commercially important trees of this forest are ebony, mahogany, rosewood, rubber and cinchona. The common animals found in these forests are elephants, monkey, lemur and deer. The one horned rhinoceros are found in the jungles of Assam and West Bengal. Besides these animals plenty of birds, bats, sloth, scorpions and snails are also found in these jungles. Continous next page

13 Tropical Deciduous Forests
These are the most widespread forests of India. They are also called the monsoon forests and spread over the region receiving rainfall between 200 cm and 70 cm. Trees of this forest-type shed their leaves for about six to eight weeks in dry summer. On the basis of the availability of water, these forests are further divided into moist and dry deciduous. The former is found in areas receiving rainfall between 200 and 100 cm. These forests exist, therefore, mostly in the eastern part of the country – northeastern states, along the foothills of the Himalayas, Jharkhand, West Orissa and Chhattisgarh, and on the eastern slopes of the Western Ghats. Teak is the most dominant species of this forest. Bamboos, sal, shisham, sandalwood, khair, kusum, arjun, mulberry are other commercially important species. The dry deciduous forests are found in areas having rainfall between 100 cm and 70 cm. These forests are found in the rainier parts of the peninsular plateau and the plains of Bihar and Uttar Pradesh. In these forests, the common animals found are lion, tiger, pig, deer and elephant. A huge variety of birds, lizards, snakes, and tortoises are also found here. Continous next page

14 The Thorn Forests and Scrubs
In regions with less than 70 cm of rainfall, the natural vegetation consists of thorny trees and bushes. This type of vegetation is found in the north-western part of the country including semi-arid areas of Gujarat, Rajasthan, Madhya Pradesh, Chhattisgarh, Uttar Pradesh and Haryana. Acacias, palms, euphorbias and cacti are the main plant species. Trees are scattered and have long roots penetrating deep into the soil in order to get moisture. The stems are succulent to conserve water. Leaves are mostly thick and small to minimize evaporation. These forests give way to thorn forests and scrubs in arid areas. In these forests, the common animals are rats, mice, rabbits, fox, wolf, tiger, lion, wild ass, horses and camels. Continous next page

15 Montane Forests In mountainous areas, the decrease in temperature with increasing altitude leads to the corresponding change in natural vegetation. The wet temperate type of forests are found between a height of 1000 and 2000 metres. Evergreen broad-leaf trees such as oaks and chestnuts predominate. Between 1500 and 3000 metres, temperate forests containing coniferous trees like pine, deodar, silver fir, spruce and cedar, are found. These forests cover mostly the southern slopes of the Himalayas, places having high altitude in southern and north-east India. Silver fir, junipers, pines and birches are the common trees of these forests. The common animals found in these forests are Kashmir stag, spotted dear, wild sheep, jack rabbit, Tibetan antelope, yak, snow leopard, squirrels, Shaggy horn wild ibex, bear and rare red panda, sheep and goats with thick hair.

16 Mangrove Forests The mangrove tidal forests are found in the areas of coasts influenced by tides. Mud and silt get accumutated on such coasts. Dense mangroves are the common varieties with roots of the plants submerged under water. The deltas of the Ganga, the Mahanadi, the Krishana, the Godavari and the Kaveri are covered by such vegetation. Royal Bengal Tiger is the famous animal in these forests. Turtles, crocodiles, gharials and snakes are also found in these forests.

17 Sarpagandha : Used to treat blood pressure; it is found only in India.
MEDICINAL PLANTS India is known for its herbs and spices from ancient times. Some 2,000 plants have been described in Ayurveda and at least 500 are in regular use. The World Conservation Union’s Red list has named 352 medicinal plants of which 52 are critically threatened and 49 endangered. The commonly used plants in India are: Sarpagandha : Used to treat blood pressure; it is found only in India. Jamun: The juice from ripe fruit is used to prepare vinegar which is carminative and diuretic, and has digestive properties. The powder of the seed is used for controlling diabetes. Arjun: The fresh juice of leaves is a cure for earache. It is also used to regulate blood pressure. Babool: Leaves are used as a cure for eye sores. Its gum is used as a tonic. Neem: Has high antibiotic and antibacterial properties. Tulsi Plant: Is used to cure cough and cold. WILDLIFE next page

18 Thank You, Best Of Luck WILD LIFE
Like its flora, India is also rich in its fauna. It has more than 89,000 of animal species. The country has more than 1200 species of birds. They constitute 13% of the world’s total. There are 2500 species of fish, which account for nearly 12% of the world’s stock. It also shares between 5 and 8 per cent of the world’s amphibians, reptiles and mammals. The elephants are the most majestic animals among the mammals. They are found in the hot wet forests of Assam, Karnataka and Kerala. One-horned rhinoceroses are the other animals, which live in swampy and marshy lands of Assam and West Bengal. Arid areas of the Rann of Kachchh and the Thar Desert are the habitat for wild ass and camels respectively. Indian bison, nilgai (blue bull), chousingha (four horned antelope), gazel and different species of deer are some other animals found in India. It also has several species of monkeys. India is the only country in the world that has both tigers and lions. The natural habitat of the Indian lion is the Gir forest in Gujarat. Tigers are found in the forests of Madhya Pradesh, the Sundarbans of West Bengal and the Himalayan region. Thank You, Best Of Luck
