Overview of photosynthesis

Question 1

Where does photosynthesis occur?

Answer 1

Chloroplasts

Question 2

How are leaves adapted for photosynthesis?

Answer 2

A large surface area, Thin so short diffusion distance, Transparent cuticle and epidermis which let light in, Numerous stomata for gaseous exchange, Arrangement of leaves that minimise shadowing

Question 3

What is the overall equation for photosynthesis?

Answer 3

6CO2 + 6H20 > (Light) > C6H1206 + 6O2

Question 4

What are the 3 main stages of photosynthesis?

Answer 4

Capturing of light energy, The light dependent reaction, The light independent reaction

Question 5

Within the chloroplast membrane there are two distinct regions. What are they?

Answer 5

The grana which are stacks of up to 100 disc-like structures called thylakoids, The stroma which is the fluid filled matrix

Question 6

What stage of photosynthesis occurs in the thylakoids?

Answer 6

Light dependent reaction

Question 7

What stage of photosynthesis takes place in the stroma?

Answer 7

Light independent reaction
