9.1 & 9.2

Question 1

ATP

Answer 1

Compound used by cells to store release energy.

Question 2

Photosynthesis

Answer 2

Process used by plants and autotrophs to capture light energy and use it to power chemical reactions that convert carbon dioxide and water into oxygen and energy-rich carbohydrates such as sugars and starches.

Question 3

Pigment

Answer 3

Light-absorbing molecules used by plants to gather the suns energy.

Question 4

Chlorophyll

Answer 4

Principal pigments plants and other photosynthetic organisms.

Question 5

Thylakoid

Answer 5

Saclike photosynthetic membrane found in chloroplast.

Question 6

NADP+

Answer 6

Carrier molecules that transfer high energy electrons from the chlorophyll to other molecules.

Question 7

Light Independent Reactions

Answer 7

Set a reaction in photosynthesis that don’t require light; energy from ATP and NADPH is used to build high-energy compounds such as sugar; also called Calvin Cycle.

Question 8

Stroma

Answer 8

Fluid portion of the chloroplast; outside the thylakoids

Question 9

Light Dependent Reactions

Answer 9

Set of reactions in photosynthesis that use energy from light to produce ATP and NADPH.
