Question

Why do cells have chloroplast and mitochondria?

Answer 1

Below

Explanation:

Chloroplast is found only in plant cells because it is used in the process of photosynthesis by plants. The green colour on the leaves of the plants are in fact chloroplasts. Hence, if leaves are variegated, where parts of the leaves are perhaps white in colour, no chloroplasts are present and so photosynthesis cannot occur there. The photosynthesis equation is given below, ![https://useruploads.socratic.org/kkX9oOT7GMrdXU7mup3A_photosynthesis_equation.jpg)

So plant cells must have chloroplasts for the plant to survive as its food is derived from the photosynthesis equation. Without glucose which is the plant's food, the plant will not survive. We need plants or else we won't have the oxygen to breathe.

Mitochondria is considered the "powerhouse of the cells". It is necessary because plants use ATP (adenosine triphosphate) and since mitochondria produces energy in the form of ATP, then plants must have mitochondria.

Answer 2

Refer to the explanation.

Explanation:

Eukaryotic plant and plant-like cells have chloroplasts, which are the site of photosynthesis. Glucose is a product of photosynthesis, and is the primary food molecule for nearly all life on the earth.

Mitochondria are found in all eukaryotic cells, including plant and plant-like cells. The mitochondria are the site of aerobic cellular respiration, in which glucose is broken down, forming ATP, the energy currency of cells.
