(Module 8)Photosyntheis

Question 1

Where does photosynthesis take place in the plant

Answer 1

In the leaves and the algae

Question 2

What cell does photosynthesis take place in

Answer 2

The chloroplast, which contains a green substance called chlorophyll

Question 3

What is the word equation of photosynthesis/what is in it

Answer 3

Light

Carbon Dioxide + water —-> glucose + oxygen

Question 4

What is the symbol equation for photosynthesis

Answer 4

Light

6CO2 + 6H2O —->C6H12O6 +6O2

Question 5

Is photosynthesis exo or endothermic

Answer 5

It is endothermic because it needs energy from its surroundings

Question 6

How is glucose used in plants?

Answer 6

1) for respiration
2) making cellulose (for strong plant cell walls)
3) making amino acid - which is then made into protein
4) stored as oils and fats - turned into lipids for storing seeds
5) stored as starch

Question 7

What limiting factors affect the rate of photosynthesis

Answer 7

If there is enough Light e.g at night
Is there enough CO2 e.g if its very warm and bright
What is the Temperature e.g winter
The amount of chlorophyll

Question 8

What is a limiting factor

Answer 8

A reactant in a chemical equation which runs out first/there is not enough

Question 9

What adaptations have leaves made for photosynthesis

Answer 9

Most leaves are broad for max surface area
Most leaves are thin so gas diffusion
They can contain chlorophyll in the chloroplast to absorb light
They have plenty of water from the xylem and the produce of photosynthesis is taken away in phloem
They have open space that allows carbon dioxide to enter the cell
