2 How do plants make their own food? Plants make their food from carbon dioxide and water in a chemical reaction called...photosynthesis.carbon dioxide(from the air)glucoseoxygenwater(from the soil)The food made by photosynthesis is the sugar glucose.Oxygen gas is also made as a by-product of photosynthesis.
3 How do plants grow?Plants need energy for photosynthesis to take place.Where does this energy come from?light energycarbon dioxide(from the air)glucoseoxygenwater(from the soil)The energy for photosynthesis comes from the Sun.Where in a plant does photosynthesis take place?
4 How do plants grow?Plant cells in the upper surface of leaves have chloroplasts which contain the green pigment called chlorophyll.light energycarbon dioxide(from the air)chlorophyllglucoseoxygenwater(from the soil)It is chlorophyll that absorbs light energy from the Sunto make photosynthesis happen.
5 Photosynthesis summary Plants make their own food by the process of photosynthesis.In this chemical reaction, chlorophyll in plant cells absorbs light energy to change carbon dioxide and water into glucose and the by-product oxygen.What is the word equation for photosynthesis?light energycarbondioxidewaterglucoseoxygenchlorophyllThis equation can be read as:“carbon dioxide and water, in the presence of light energyand chlorophyll, produces glucose and oxygen”.
6 How about at night? Respiration Carbon dioxide oxygen water Glucose + oxygen carbon dioxide + water (+energy)
7 How are leaves adapted?Leaves are small ‘factories’ that produce food for plantsby photosynthesis.Leaves are adapted so that photosynthesis can take place.Plants need carbon dioxide, water, sunlight and chlorophyll to carry out this important process.What features of leavesmake them suitable for photosynthesis?
8 How are leaves adapted?The features of leaf that make it suitable for photosynthesis are:A leaf is broad and flat to capture lots of sunlight.carry water to the leaf and take food from the leafto the rest of the plant. Veinsalso help to support the leaf.Certain plant cells contain chloroplasts with chlorophyll.Small holes called stomata in the underside of a leaf allow gases in and out.Veins
9 How does water enter a plant? Water is one of the raw materials needed for plants to carry out photosynthesis.How does water enter a plant?Water from the soil enters a plant through the roots.You can’t normally see them butroots are a very important part of a plant.Why are roots branched and spread out through the soil?
10 Water movement inside the plant Xylem is responsible for the transportation of water.Phloem is responsible for the transportation of glucose (sugar).
11 How are roots adapted? Roots are branched and spread out for two reasons:to absorb water (and mineral salts)from a large amount of soil.to anchor the plant in the soil.Taking a closer look, roots arecovered in root hair cells.Root hair cells have thin wallsand a large surface area to helpthem absorb lots of water.How are roots adapted to their job?water
