Photosynthesis

Question 1

Which gas is needed for photosynthesis?

Answer 1

Carbon Dioxide

Question 2

What type of energy is needed for photosynthesis to happen?

Answer 2

Light

Question 3

What is produced as a waste by-product from photosynthesis?

Answer 3

Oxygen

Question 4

The green pigment used to absorb energy from the sun for photosynthesis is :

Answer 4

Chlorophyll

Question 5

What is the word equation for photosynthesis?

Answer 5

Carbon Dioxide + Water (+ Light energy) ➡️ Glucose + Oxygen

Question 6

Photosynthesis takes place, where?

Answer 6

Leaf cells

Question 7

What is photosynthesis?

Answer 7

Photosynthesis is the chemical change which happens in the leaves of green plants. It is the first step towards making food. During this reaction, carbon dioxide and water are converted into glucose and oxygen. The reaction requires light energy, which is absorbed by a green pigment called chlorophyll. Photosynthesis takes place in leaf cells. These contain chloroplasts, which are tiny objects containing chlorophyll.

Question 8

What three factors limit the rate of photosynthesis?

Answer 8

1. ) Light energy
2. ) Carbon dioxide concentration
3. ) Temperature
