2 The KingdomLiving thingsAnimalsFungusProtistMoneransPlantsThere are over 2 million types of living things in the world. To avoid confusions, scientists have sorted, or ‘classified’, them into groups according to their similarities and differences. New discoveries are being made all the time and added to the classifications.Most scientist divide the entire living world into five groups, called Kingdom. These kingdom are: animals, fungus, protists, monerans and plants .This presentation explains more about plant.Click the forward button, for more informationGlossarySlide presentation
3 What are plants? Glossary Slide presentation Plants are the key to life on Earth. Without them many other living organisms would soon disappear. This is because higher life forms depend on plants, either directly or indirectly, for their food.Most plants such as green plant are able to make their own food by using a sunlight, this process is called photosynthesis.All plants fall into two categories. Flowering plants, which produce true Flower such Flower, Grasses and Trees on the other there's non-flowering plants “primitive” plants, such as Mosses, Liverworts, Horsetails and Ferns.GlossarySlide presentation
4 Characteristics of mosses and liverworts Mosses and liverworts are small plant that often grow in clumps. Instead of root, slender growths, called rhizoids, anchor them into the soil. Most mosses and some liverworts have thin leaves, but liverworts usually have flat, rounded leaves.Characteristics of mosses and liverwortsOften grow in clumpsGrow in damp places, such as rainforests, freshwater areas, and dogSpread by making sporesAbsorb water and nutrients directly through their leaves have two distinct stages in their life cycle.Use sunlight to their own food through photosynthesisClick next for more information
5 Glossary Slide presentation Mosses and liverworts do not have flower or seeds. Instead, they reproduce and spread by producing spores, which are tiny, dust-like particles.The life cycle of a moss or liverwort plat has two, very different stages. In the first stage, the green, leafy moss plant (gametophyte)grows male and female sex organs, which produce sex cell. The male sex cell swim through water on the surface of the plant and fertilise the female sex cells.In the second stage, the fertilised cells grow into smaller plants called Saprophytes. These produce capsules containing thousand of spores. The spores are released and spread by the wind or water, and they grow into new, leafy plants.GlossarySlide presentation
6 Characteristics of Ferns Ferns are green, non- flowering plant with long narrowing leaves. The leaves of many ferns are lacy and consist of hundreds of tiny leaflets. Ferns vary in size from small plants with leave only a few centimetres long, to tall fern trees with leave up to 6 metres long. The leave covered in a waxy coating to prevent them drying out.Characteristics of FernsGrow in damp, shady places, (for moisture) such as riverbanks and woodlands.Have green leave that are tightly coiled at firstSpread by making spores, which grow in tiny capsules on the undersides of the leavesWater and nutrients travel up the roots to and through the stems and leavesHave two distinct stages sin their life cycleClick next for more information
7 Ferns have small roots anchored to an underground stem Ferns have small roots anchored to an underground stem. The leaves grow from small buds at the base of the stem, inside which each leaf is tightly coiled. Each bud take up to three years to develop. When it is fully grown, the bud unrolls and the leaflets rapidly open out.There are about 12,000 species of fern in the world today, each with different shape leaves. All leave have a stalk, and one or more leaves. Simple leaves have a single blade. Other have leave divided into leaflets that are themselves divided, called bipinnate leave.
8 Characteristics of Horsetails Horsetails are upright plants with rigid stems surrounded by rings of branches. About 300 million years ago, huge horsetail trees grew in vast, steaming swamps. Today there are under 30 smaller horsetail species. They are usually found in damp places, near rivers and lakes, or in swamps.Characteristics of HorsetailsGrow in damp places, such as near rivers and lakes, or in swampsRing of branches surround the stemsWater and nutrients travel from root to stems and branchesLeaves are like tiny scales around the stemsHave two distinct stage in their life cycleRelated to Club mosses (which are not mosses)GlossarySlide presentation
9 Characteristics of Conifers Conifers are trees or shrubs that grow seeds in woody cones. The word ‘conifer’ comes from the Latin word meaning ‘cone-plant’. Most conifers are evergreen, which means they are leafy all year round.Typical conifer trees have tall, straight trunks and narrow, symmetrical (regularly arranged) branches.Characteristics of ConifersTree of shrubLeaves are sharp needles or tiny scalesLeaves are leathery, covered in a waxy outer layerMost are evergreen (Keep their leaves all year round)Seeds grow in conesOne main stage in their lie cycleClick next for more informationGlossarySlide presentation
10 Cones and seedsCones differ in size and appearance according to their sex and their species. Pollen grows on male cones, which are small and light. The pollen is carried by the wind to young female cones, which are larger, with soft scales.Once the female cone has been fertilized, it scales close. The seeds grow inside it scales close. The seeds grow inside it for up to three years. By this time the female cone is large and heavy and wood-like. When the weather is warm, the cone opens and releases seeds with thin, brown wings, which are carried away by the wind.GlossarySlide presentation
11 Characteristics of Flowering plants Flowering plants make up the largest group of plants in the plant kingdom. They grow in the form of trees, shrubs or herbaceous (soft-stemmed) plants. Flowering plants produce flowers, and seeds enclosed in fruits. The fruits vary from soft fleshy strawberries to hard acorns.Characteristics of Flowering plantsCan be trees, shrubs or herbaceousHave roots, stems, leaves, flowers, and fruitsHave flowers made up of the sepal, petals, stamen and carpelThe female sex cell, the ovule, is enclosed inside the ovaryThe seeds grow inside the ovary, which becomes the fruitGlossarySlide presentation
12 Grasses The Grass plant Grasses are the world’s most widespread type of flowering plants. There are about 9,000 species, many of which provide essential food for people and animals. Rice, Wheat and Maize provide the basic food for most of the world’s population. They are called cereal crop. Other cereal crops include rye, barley and oats.The Grass plantGrass plants often grow close together to form a turf. New branches grow at ground level. A mass of tangled roots grows into a mat just below the ground. Grasses are wind pollinated. Their flowers produce dusty pollen that causes hay fever in many people.
13 Glossary Animal: Protists: A living creature that can move and feel such as bird, mammals, amphibians, fish and reptiles.Protists are organisms in the kingdom Protista. These organisms are eukaryotes meaning they are made up of single or multiple cell which all contain a nucleus enclosed by a membrane.Fungus:A plant without leaves, flower or green colouring, such as mushroom. It usually grows on old wood or food, wall and some can be harmful.Photosynthesis:The process used by plant to make food carbon dioxide in the air and water from the soil.Fertilize:To put a male seed into an egg, female plant or animal so that a fruit or a animal starts to develop.Gametophyte:A stage in the life cycle of plants in which the sex cells are are produced.Herbaceous:A plant with soft stem.Monerans:Monerans are one-cell organisms that have no nucleus or organelles
