Photosynthesis Flashcards
Green plants absorb light energy using …. In their leaves.
Chlorophyll
What do plants use light energy for?
To react carbon dioxide with water to make a sugar called glucose.
What is glucose used for in plants?
Used in reparation or converted into starch and stored. Oxygen is produced as a by-product.
What factors affect the rate of photosynthesis?
- temperate
- carbon dioxide levels
- concentration
- light intensity
What is the equation of photosynthesis?
Carbon dioxide+water–) glucose+oxygen
Increasing light intensity will ….. The rate of photosynthesis.
Boost
How do plants and algae store glucose?
As insoluble products such as starch and fats and oils.
What is glucose used for in plants?
- respiration
- cellulose (strengthens cell wall)
- proteins (such as enzymes and chlorophyll)
What do plants need to make protein?
Nitrates
What is the waste by-product of photosynthesis?
Oxygen
What type of energy is needed for photosynthesis?
Light
What do plants need nitrate ions?
To make protein.
Fats, oils and starch are used by plants for storage. What do they have in common?
They are all insoluble.
