Photosynthesis 3.4

Question 1

Photosynthesis

Answer 1

A process that captures energy from sunlight to make sugars that store chemical energy.

Question 2

Directly or indirectly, the energy for almost all organisms begin as….

Answer 2

sunlight

Question 3

Plants absorb _____ _______ in order to carry out _____________.

Answer 3

1.)visible light
2.)photosynthesis

Question 4

A molecule contained in chloroplasts that absorbs some of the energy in visible light.

Answer 4

Chlorophyll

Question 5

Plants have to maintain two types of Chlorophyll:

Answer 5

Chlorophyll A and Chlorophyll B

Question 6

Photosynthesis takes place in two stages

Answer 6

1.)Light dependent reactions
2.) Light independent reactions (AKA the Calvin cycle)

Question 7

Light Dependent Reactions/ Give 6 main points

Answer 7

• Capture energy from sunlight
  -Take place within and across the membrane of the thylakoids
• Require water and sunlight
  -Chlorophyll absorbs sunlight
• Oxygen is released
  -Energy is transferred to molecules that carry energy, such as ATP.

Question 8

Light Independent Reactions/ 6 main points

Answer 8

• Occur in the stoma of chloroplasts
  -Carbon dioxide is needed
• use energy from light dependent reactions
  -from sugars– usually glucose C6 H12 O6
  -Energy is stored in the sugars(AKA Calvin cycle)
