Question

to perform photosynthesis, plant cells need to capture light energy from the sun.
light energy is captured by molecules of a substance called chlorophyll. chlorophyll is found inside the cells in round, green structures called chloroplasts. photosynthesis takes place inside the chloroplasts.
complete the paragraph.
photosynthesis takes place inside a called a chloroplast.
chloroplasts use chlorophyll to capture the needed for photosynthesis.

Explanation:

The text mentions that chloroplasts are structures inside plant cells where photosynthesis occurs. Chlorophyll in chloroplasts captures light energy. So, for the first blank, the structure is what's needed (since chloroplast is a structure). For the second blank, light energy is what chlorophyll captures for photosynthesis.

Answer:

Photosynthesis takes place inside a structure called a chloroplast. Chloroplasts use chlorophyll to capture the light energy needed for photosynthesis.
