Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]

Studying a picture of a cell taken with an electron microscope, you find that the cell has no nucleus and no mitochondria, but it does have a plasma membrane and a cell wall. You conclude that the cell is probably from a(n) ____

A	animal
B	plant
C	prokaryote
D	extinct organism

Explanation:

Detailed explanation-1: -Plant cells have a cell wall, as well as a cell membrane. In plants, the cell wall surrounds the cell membrane. This gives the plant cell its unique rectangular shape. Animal cells simply have a cell membrane, but no cell wall.

Detailed explanation-2: -Plasma (Cell) Membrane Using the transmission electron microscope (TEM), the plasma membrane has a trilaminar appearance which has been designated as the “unit membrane” (unit membrane). The trilaminar structure is visualized as a dense outer layer, a clear staining middle, and dark staining inner layer.

Detailed explanation-3: -Prokaryotic cells are surrounded by a plasma membrane, but they have no internal membrane-bound organelles within their cytoplasm. The absence of a nucleus and other membrane-bound organelles differentiates prokaryotes from another class of organisms called eukaryotes.

Detailed explanation-4: -Ribosomes are only visible with the electron microscope.
