Photosyntheis Flashcards
Photsoyntheis endothermic or exothermic
Endothermic reaction
Carbon dioxide + water
Equals glucose + oxygen
Photosyntheis use
Respiartion and storing for glucose
Leaf adaptations
Most leaves are beoad,giving them a big surface sarea for light to fall on
Leaf adaptaions
They have air spaces that allow carbon dioxide to get cells,and oxygem to leave by diffusion
Algae and photosynthesis
Algae are adapted by photosynthesising in water
Rate of photosyntheis
Light
Carbon dioxide
Temperature
Light
If there is high levels of light there will be plently of photosynthesis and vice versa
Temperature
Temperature rises the rate of photosynthesis increase and sppeds up but not too high or enzymes won’t work
Carbon dioxide concentration
Plants need enough dioxide to photosyntheis and for food
Chloryphll
Chlorphyll attracts sunlight which allows more photosynthesis
Using glucose
The glucose is used for energy for the cells
Cellulose for strength and starch
Cellulose for cell protection and for food and fibre for plant
Starch
Starch is stored in cell as an e energy store.
Carnvirous plants
Eat inscets to gain minerals only eat inscets if they live in bog or non-mineral rich arae
