Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
animals have chloroplasts
A
false
B
true
C
Either A or B
D
None of the above
Explanation: 

Detailed explanation-1: -Animal cells do not contain chloroplasts. Plants cells have chloroplasts as well as mitochondria, but animals have only mitochondria. Thus, the given statement is true.

Detailed explanation-2: -It is a common perception that animal cells do not have chloroplasts, the organelles that performs photosynthesis. Yet, a small number of sea slugs are able to incorporate carbon from CO2 by performing photosynthesis using sequestered chloroplasts from the macroalgae in their diet.

Detailed explanation-3: -Both animal and plant cells have mitochondria, but only plant cells have chloroplasts. Plants don’t get their sugar from eating food, so they need to make sugar from sunlight. This process (photosynthesis) takes place in the chloroplast.

Detailed explanation-4: -Chloroplasts are exclusively found in plants and photosynthetic unicellular organisms and, hence, animal cells lack chloroplast.

Detailed explanation-5: -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 of water and nutrients. It also helps maintain the shape of the cell.
