B.2 The Rate Of Photosynthesis

Question 1

What are the limiting factors of photosynthesis

Answer 1

Light intensity, carbon dioxide concentration and temperature

Question 2

Why are Chlorophyll levels in the leaf important when it comes to limiting factors?

Answer 2

If the amount of Chlorophyll in a leaf is limited in any way, less Photosynthesis will take place

Question 3

How does light limit Photosynthesis?

Answer 3

The brighter the light the faster the Photosynthesis

Question 4

How does temprature affect Photosynthesis?

Answer 4

Photosynthesis is controlled by Enzymes, most Enzymes are deduned by tempatures of 40-50C

Question 5

How does Carbon Dioxide affect Photosynthesis?

Answer 5

Plants need Carbon Dioxide to make glucose, the air is made of 0.04% Carbon Dioxide which limits the rate of Photosynthesis

Question 6

When testing the rate of photosynthesis from pondweed, what liquid do we use?

Answer 6

Carbonate Solution
