Why is a variegated plant considered heteroplasmic? O The plant has mutant and wild-type chloroplast DNAS distributed amongst the cells in different ratios. The plant has only two types of cells, one with only mutant chloroplast DNAS and one with only wild-type chloroplast DNAS. O All of the plant's cells have mutant and wild-type chloroplast DNAS. All of the plant's cells have mitochondria and chloroplasts.

Photosynthesis

Plants have a capacity that we humans can only imagine— the ability to produce food from sunlight. Sure, we can prepare some dishes that we can savor on, but it become possible because of the plants (as they serve as a producers of all the raw materials required). Photosynthesis is the method of assembling carbohydrates with the aid of sunlight.
