14-17 - Photosynthesis + Rate of Photosynthesis Flashcards
What are the thre limiting factors of photosynthesis?
Light intensity
CO2
Temperature
What happens if a plant is too hot?
Enzymes are denatured
What is the equation for photosynthesis?
CO2 + water -> glucose + oxygen
What organs are in a plant?
Stems
Roots
Leaves
What is the job of the mesophyll?
Where photosynthesis occurs
What do xylem and phloem do?
Transport substances around the plant
What does the epidermal tissue do?
Cover the plant
What gases diffuse in and out of the leaf?
O2 and CO2
What are the five ways that plants use glucose?
Respiration
Making cell walls
Making proteins
Storing in seeds
Storing as starch
What happens when glucose is used in respiration?
Energy is released and the rest of the glucose is converted into other substances
What is glucose converted into for the making of cell walls?
Cellulose
What is the process of making proteins?
Glucose and nitrate atoms combine to make amino acids, which are then made into proteins
How is glucose stored in seeds?
It is turned into lipids (fats and oils)
What is starch?
Glucose stored in roots stems and leaves for when photosynthesis rates are low
It is insoluble
What do plants take from the soil?
Nitrate ions
