Sample Questions

1multiple correct

Which raw materials are needed for photosynthesis?

Show answer

Carbon dioxide, Water, Sunlight

The raw materials for photosynthesis are carbon dioxide (from air), water (from soil), and sunlight (energy source). Oxygen and glucose are products, not raw materials.

2multiple choice

What causes stomata to open during the day?

Show answer

Guard cells become turgid

During day, photosynthesis in guard cells produces glucose, making cell sap hypertonic. Water enters by endosmosis, making guard cells turgid and causing stomata to open.

3multiple choice

Which pigment is most important for photosynthesis?

Show answer

Chlorophyll

Chlorophyll is the most important photosynthetic pigment. It traps solar energy and has a magnesium-containing head. Carotene and xanthophyll are accessory pigments.

4multiple choice

During which process is water split into hydrogen and oxygen?

Show answer

Photolysis

Photolysis is the process of breaking down water molecules into H+ and OH- ions using light energy. This occurs during the light reaction in thylakoids.
