chapter 10:photosynthesis

Question 1

Identify examples of autotrophs and whether they are considered producers or consumers

Answer 1

are producers.

They generate their own food for energy.

EX) plants

Question 2

Identify examples of heterotrophs, and whether they are considered producers or consumers

Answer 2

are consumers.

They cannot produce their own food for energy, so they rely on other organisms or animal.

Ex). Animals

Question 3

Identify examples of photoautotrophs and whether they are considered producers or consumers

Answer 3

are producers.

Photoautotrophs orginisms USE light to generate their own food for energy.

Ex). Other Plants, Algae

Question 4

Explain light reaction stages of photosynthesis

Answer 4

Occurs in the THYLAKOIDS, converts light into energy to chemical energy.

Water splits, generates into ATP and NADPH to power Calvin cycle.

Question 5

Explain Calvin cycle stages of photosynthesis

Answer 5

Occurs in the STROMA,

The fixation of C02 using ATP and NADPH from light reaction produces sugar.

Question 6

What’s the process of C3 photosynthesis including the benefits

Answer 6

Carbon dioxide is fixed into a three-carbon compound during the Calvin Cycle.

Works well under moderate light and temperature conditions.

Question 7

What’s the process of C4 photosynthesis including the benefits of each

Answer 7

Spital seperation

fixation mesophyll, but Calvin occurs in bundle-sheath.

More efficient in hot and dry conditions

Question 8

What’s the process of CAM photosynthesis including the benefits of each

Answer 8

Temporal Seperation

the STROMA, opens at night allowing C02 fixations. Then C02 is released when there’s sunlight.
