3. Using the onion cell diagram above, which organelle is responsible for the greenish color?

Chloroplast

Explanation:

The organelle is responsible for the greenish color is "the chloroplast".

Chloroplasts are seen as these numerous, green, disc-like structures are responsible for doing photosynthesis. This means that the making food for/by the plant is aided by the chloroplast. The greenish color is gotten from the presence of chlorophylls, green-pigmented molecules. They are involved in harvesting light that is used use for photosynthesis. These chloroplasts can be seen as when they are pushed toward the edges of the cell.

for  example, forests have higher evapotranspiration than other ecosystems,  such  as grasslands, because of their deeper roots and greater leaf area. thus forests have a net moistening effect on the atmosphere and become a moisture source for downwind ecosystems.
