Plant Biology Flashcards
Conditions for seed growth..
Water, soil, air, warmth, ligbt
Conditions for seed germination…
Water, soil, air(oxygen), warmth
What is the green pigment that traps sunlight called?
Chlorophyll
What does photosynthesis need??
Chlorophyll + light energy
What does photosynthesis occur in?
Leaves
What is the equation for photosynthesis?
carbon dioxide + water—> oxygen + glucose
Why is glucose made by photosynthesis important to plants ?
Can be..
Stored in fruit/seed (eg orange)
Converted + stored as starch (in leaves)
Converted to cellulose (to make cell wall)
Why is photosynthesis important to us?
Because plants..
Are food source for animals
Produce oxygen + keeps balance of this in the air
Are important raw materials eg wood
What is needed for photosynthesis?
Carbon dioxide
Water
Light (a source of energy)
Chlorophyll
What is made due to photosynthesis?
Glucose, oxygen
What factors affect photosynthesis?
Light intensity
Carbon dioxide concentration
Temperature
