Why do plants need both chloroplasts and mitochondria?

1 Answer

Chloroplast to make their food and mitochondria to respire.


Chloroplasts are present in photosynthetic plants and is responsible for making the food of the plant. Oxygen is released out from the chlorophyll while making food and this food is used by the plants themselves too.

On the other hand, mitochondria also known as the power house of the cell, uses this oxygen in order to create ATP which is used for various purposes like active transport, releasing minerals and many more in plants.

So Chlorophyll produces Oxygen and Mitochondria utilizes it.

It is important to note that plants need both chloroplasts and mitochondria because without one organelle say the mitochondria the entire cell would be unable to carry out its life activities. This is because if there was no mitochondria there would be on oxidative phosphorylation and the cell would have no ATP production and would deplete its ATP reserves very quickly and die. Thus, both organelles are equally important for normal cellular function.
