CELL STRUCTURE

Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Animal cells have all of the following except
A
mitochondria
B
chloroplasts
C
a nucleus
D
a cell membrane
Explanation: 

Detailed explanation-1: -Animal cells have centrosomes (or a pair of centrioles), and lysosomes, whereas plant cells do not. Plant cells have a cell wall, chloroplasts, plasmodesmata, and plastids used for storage, and a large central vacuole, whereas animal cells do not.

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: -Chloroplasts are the food producers of the cell. The organelles are only found in plant cells and some protists such as algae. Animal cells do not have chloroplasts. Chloroplasts work to convert light energy of the Sun into sugars that can be used by cells.

Detailed explanation-4: -Animal cells have a cell membrane. They also have organelles such as a nucleus, mitochondria, and the Golgi apparatus. However, they do not have. Chloroplasts can only be found in photosynthetic cells such as those found in plants and green algae.

Detailed explanation-5: -Cell wall and chloroplasts are not present in the animal cell.
