Answer 1

Chloroplasts in the leaves of a
Plant 🍃

Question 2

Name of The green pigment in the leaves?

Answer 2

Chlorophyll

Question 3

What type of reaction is photosynthesis?

Answer 3

Endothermic

Question 4

What type of energy is used in photosynthesis?

Answer 4

Light energy

Question 5

Limiting factor?

Answer 5

Anything that limits the rate of a reaction when it is in short supply

Question 6

Give the limiting factors of photosynthesis

Answer 6

Temperature
Carbon dioxide concentration
Light intensity
Amount of chlorophyll

Question 7

Describe how light intensity affects the rate of photosynthesis

Answer 7

Increasing light intensity increases the rate of photosynthesis until another factor becomes limiting

Question 8

Describe how CO2 concentration affects the rate of photosynthesis

Answer 8

Increasing CO2 concentration increases the rate of photosynthesis until another factor becomes limiting

Question 9

Describe how temp affects the rate of photosynthesis

Answer 9

Increasing temp increases the rate of photosynthesis as the reaction rate increases and at high temperatures 🤒 enzymes are denatured so the rate of photosynthesis quickly decreases

Question 10

Y r limiting factors important in the economics of growing plants in the greenhouses?

Answer 10

Greenhouses need to produce the maximum rate of photosynthesis whilst making profit

Question 11

How do plants use glucose produced in photosynthesis?

Answer 11

Respiration
Convert it to insoluble starch for storage
Produce cellulose to strengthen cell walls
Produce fat or oil for storage
Produce amino acids for protein synthesis
