Reactions In Plants

Question 1

Photosynthesis

Answer 1

Is a series of chemical reactions that takes place in the leaves of a plant. The energy is transferred by light and becomes stored in glucose.

Only happens during daytime

Question 2

Equation of photosynthesis

Answer 2

Carbon dioxide + water —> glucose + oxygen

Question 3

What substance is found in leaves in order for the plant to photosynthesise?

Answer 3

Chloroplasts with chlorophyll

Question 4

Limiting factors

Answer 4

Variable that slows down the rate.

• > less light, photosynthesis slower
• > shortage of raw materials, photosynthesis slower

Question 5

Aerobic respiration

Answer 5

A type of respiration in which oxygen is used to release energy from substances, such as glucose.

Glucose + oxygen —> carbon dioxide + water

Happens all the time

Question 6

Phloem vessels

Answer 6

Chains of phloem cells that carry the glucose dissolved in water all around the plant.

-> this is how roots get glucose for respiration.

Question 7

Where is oxygen obtained from?

Answer 7

The soil including potassium, nitrates and water
