what are chloroplasts? why are they green? how is the green colour plant of a great importance to the whole living world? explain?

Chloroplasts are structures found in the cytoplasm of plant cells that are the site for photosynthesis. They are green because they contain a pigment called chlorophyll.  Chlorophyll absorbs light to bring about the photosynthesis reaction. Light energy is crucial to initiate photosynthesis.

Photosynthesis allows the plant to convert carbon dioxide from air and water absorbed from the roots into oxygen and glucose, which are foods for plants. By releasing oxygen to air through photosynthesis, other living things can breathe in oxygen so that energy can be generated through another process, called respiration. Respiration is like the reverse reaction of photosynthesis, but it turns glucose to energy that supports living things.

Because plants also respire to generate energy, by using the glucose produced from photosynthesis, it also supports the food chain in the living world. Other organisms can consume plants for their energy.

In the end, chloroplasts and the chlorophyll inside are very important to the living world.

ya the other dude is right
