Photosynthesis

Question 0

What is the word equation for photosynthesis

Answer 0

CO2+water———> (by light energy and chlorophyll)—>glucose + oxygen

Question 1

What is photosynthesis

Answer 1

The process in which green plants make food

Question 2

What is made first in photosynthesis and why may this be broken down

Answer 2

Glucose- broken down to release energy in respiration or it is converted into starch for storage or cellulose to make cell walls

Question 3

What are the 2 stages of photosynthesis

Answer 3

Light independent stage and the carbon fixation stage

Question 4

Describe the stages of the light independent stage

Answer 4

1) light is converted into chemical energy in the form of ATP
2) the ATP is synthesised from the ADP , phosphate and the energy
3) some of the trapped energy is used to split eater to give hydrogen and oxygen
4) oxygen diffuses out of the cell
5) hydrogen is carried to the second stage by a hydrogen accepter

Question 5

Describe what happens in the carbon fixation stage of photosynthesis

Answer 5

The ATP and hydrogen produced in the first stage are used to convert carbon dioxide to glucose

Question 6

What is fat glucose

Answer 6

It is used for respiration and is converted into and stored as starch or converted into the structural cell wall component- cellulose

Question 7

What are limiting factors and give examples of them

Answer 7

They are factors that if in short supply, hold up the
Recess of photosynthesis
Examples: light intensity, CO2 concentration + temperature
