photosynthesis By Charlie hingley and Victoria fellows
How plants use glucose? 1.For respiration ( is not breathing it is converting the glucose make in photosynthesis into energy at night!) 2.For chlorophyll 3.Stored as starch 4.Stored in seeds 5.Making cell walls 6.Making proteins.
How do plants make food? Plants make their food by photosynthesis. They take carbon dioxide from the air and water from the soil, in their leaves they use energy from the sunlight to make the carbon dioxide and water react, together this is how they make their food! Some of the energy in the sunlight is absorbed by a green pigment called chlorophyll
What happens if the plant doesn’t need glucose? If the plant doesn’t need glucose it has made straight away, it turns it into starch. These are big molecules and unlike glucose, they cannot diffuse out of cells. Starch is stored in the plants leaves. Just like glucose starch stores energy that the plan can use whenever it needs it.
What is the formula for photosynthesis? Carbon dioxide + water glucose + oxygen. CO2 + H2O + energy O2 + C6H12O6 Fact: Some of the energy you are using today might have begun its journey as a sunbeam in Canada!
Facts! 1.Respiration - is not breathing its converting the glucose made into photosynthesis into energy at night 2.Chlorophyll – glucose makes chlorophyll and chlorophyll makes glucose! 3.Starch – how the plants stores glucose – take up less space. Stored in: roots, leaves and stems. 4.Seeds- glucose is turned into fats and oil for storage in seeds they use energy when they start to grow 5.Cell walls- glucose=> cellulose which makes cell walls 6.Proteins- growth + repair - glucose + nitrates to make proteins.
