Plants have chloroplasts to carry out photosynthesis, but animals do not. Which organisms have mitochondria to carry out cellular respiration?
A
animals
B
plants
C
both
D
neither
Explanation: 

Detailed explanation-1: -Mitochondria and chloroplast are organelles found in a plant cell. However, the chloroplast is absent in an animal cell, but mitochondria is found in both. Mitochondria generates energy for the cell in the form of ATP using oxygen and nutrients. Chloroplast is the site for photosynthesis in a plant cell.

Detailed explanation-2: -Because animals get sugar from the food they eat, they do not need chloroplasts: just mitochondria. Both plant and animal cells have vacuoles. A plant cell contains a large, singular vacuole that is used for storage and maintaining the shape of the cell. In contrast, animal cells have many, smaller vacuoles.

Detailed explanation-3: -In a plant cell, chloroplast makes sugar during the process of photosynthesis converting light energy into chemical energy stored in glucose. In mitochondria, through the process of cellular respiration breaks down sugar into energy that plant cells can use to live and grow.

Detailed explanation-4: -After photosynthesis, the sugar is broken down by the mitochondria to produce energy. Animals don’t need chloroplasts because they acquire sugar from their diet; they just need mitochondria. Vacuoles are found in both plant and animal cells.
