Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Which organelle is present in bacteria (prokaryote) and plant cells but not animal cells
A
cell mebrane
B
lysosome
C
cell wall
D
nucleus
Explanation: 

Detailed explanation-1: -Plant cells have a cell wall, chloroplasts and other specialized plastids, and a large central vacuole, which are not found within animal cells.

Detailed explanation-2: -Thus, Chloroplast is the organelle that is found in a plant cell but not in an animal cell.

Detailed explanation-3: -Plasma Membrane-All living cells have a plasma membrane that encloses their contents. In prokaryotes, the membrane is the inner layer of protection surrounded by a rigid cell wall. Eukaryotic animal cells have only the membrane to contain and protect their contents.

Detailed explanation-4: -A structure that is present in a bacterial cell but absent in a plant or animal cell includes a plasmid and a nucleoid. Pili, a capsule or a cell envelope, and flagella are other structures that are present on the outer surface of a bacterial cell but are absent in a plant or animal cell.

Detailed explanation-5: -Plant cell needs cell wall whereas animal cell do not because the plants need rigid structure so that they can grow up and out . All cells have cell membranes, and the membranes are flexible. So animal cells can have various shapes, but plant cells only have the shapes of their cell walls.
