Cell Transport and Photosynthesis

Front

What is the purpose of photosynthesis?

Back

To make sugar.

Front

What happens to a bag made of a semipermeable membrane if it loses mass?

Back

The solution it was placed in was hypertonic.

Front

What is the first step in the light dependent reactions of photosynthesis?

Back

Photosystem II absorbs light energy.

Front

Define osmosis.

Back

The movement of water molecules across a selectively permeable membrane from an area of higher concentration to an area of lower concentration.

Front

Which reactant is used in light independent reactions?

Back

Carbon dioxide.

Front

What is diffusion?

Back

The movement of molecules from an area of higher concentration to an area of lower concentration.

Front

What is the role of chlorophyll in photosynthesis?

Back

Chlorophyll absorbs light energy, primarily in the blue and red wavelengths.

Front

What are the two main stages of photosynthesis?

Back

Light-dependent reactions and light-independent reactions (Calvin cycle).

Front

What is a hypertonic solution?

Back

A solution that has a higher concentration of solutes compared to another solution.

Front

What is a hypotonic solution?

Back

A solution that has a lower concentration of solutes compared to another solution.
