What are the round membrane disks inside the chloroplast where the light reactions take place?

• Thylakoids

• Cristae

• Ribosomes

• Cytoplasm

Answer explanation

Select all that apply: How do plants use the glucose that they make in photosynthesis?

• They break it down for energy

• They use it to make their cell walls

• They use it for locomotion

• They convert it into polypeptides

Answer explanation

Plants use glucose for cellular respiration, just like animals.

Plants also use their glucose to make cellulose to build cell walls.

Match the following parts of the cell to their functions:

• Thylakoids

• Organelle responsible for photosynthesis in plants

• Stroma

• Membrane in the chloroplast where light reactions occur

• Chlorophyll

• Green pigment that absorbs light energy

• Chloroplast

• Space in the chloroplast where the Calvin Cycle occurs

Select all that apply: What kinds of organisms can do photosynthesis?

• Plants (with chloroplasts)

• Animals

• Bacteria (with chlorophyll)

• Fungi

Answer explanation

Chloroplasts likely evolved from photosynthetic bacteria - bacteria with chlorophyll in their membranes.

Organisms with chlorophyll or chloroplasts can do photosynthesis.
