Why must plants cells have both the mitochondria and chloroplast?

Answer 1

Mitochondria are not natively part of an organism - animal or plant. They were a symbiotic invasion very early in evolution. They are living things, respire and consume energy, and have their own DNA.

The MtDNA as it is known, is constructed from maternal material, and thus it consists of your mother's MtDNA, and this genetic marker has been of great value in tracing lineage over evolutionary ranges.

But their importance is that they enhance the ATP energy producing reaction in the body.

[I understand that there is a 'native' ATP process available but much less efficient then that of the Mitochondria. But I'm not a biochemist. ]

Answer 2

mitochondria and chloroplasts are two very different organelles with different functions. the function of chloroplasts is basically to make food, by trapping light energy to convert water and carbon dioxide to form oxygen and glucose. this process is called photosynthesis. the function of the mitochondria is to provide energy for the cell's use, by extracting the energy from the glucose molecules, and storing them in adenosine tri-phosphate(ATP) molecules. The ATP molecules will then diffuse out of the mitochondrion for the cell's use.

Answer 3

Mitochondria is used to make the cell go through cellular repiration which turns glucose into energy just because plant cells get there glucose from the sun does not mean they do not need energy therefor plant cells use mitochondria to produce energy for the cell to grow and reproduce

Answer 4

I think its because chloroplast's main function is photosynthesis for which carbon dioxide is essential which is got from mitochondria which is a seat of aerobic cellular respiration(i.e oxygen is taken in and CARBON DIOXIDE IS LIBERATED).Thus cells that contain chloroplast also contain mitochondria.

Hope this helps..... :)

Answer 5

The mitochondria is the site of respiration (producing ATP- the energy molecule, from glucose and oxygen), and chloroplast is the site of photosynthesis (changing carbon dioxide and water into glucose and oxygen with the help of light, ATP and chlorophyll). In order to survive the plant must respire, so ATP can be produced for it to photosynthesize.

Answer 6

The chloroplasts use solar energy to turn water and carbon dioxide into sugars. The plan cell then needs the mitochondria to break down the sugars to get useable energy.

Answer 7

Chloroplast is needed to photosynthesis. Respiration is done through mitochondria

Answer 8

Chloroplast is needed for photosynthesis. Mitochondria are needed for respiration.

Answer 9

for energy int the form of ATP
