Chapter 10: Photosynthesis

Question 1

What is photosynthesis

Answer 1

The process of converting light energy into chemical energy directly or indirectly

Question 2

Autotroph

Answer 2

Produce and consume their own energy

Question 3

Heterotroph

Answer 3

Consume others to get energy

Question 4

Decomposers

Answer 4

Most bacteria and fungi leave on energy of decomposing organic things

Question 5

What thing on the leaves let gases and water in and out

Answer 5

Stomata

Question 6

Where can chloroplasts be found

Answer 6

Question 17

What is photosystem

Answer 17

a light-capturing unit located in thylakoid membranes consists of a reaction-center complex surrounded by numerous light-harvesting complexes.
