Question

The main difference between plant and animal cell is
A) Animal cells lack cell wall
B) Plant cell has no cell wall
C) Animal cell has a rigid cell wall
D) Plant cells lack cell membrane

Answer 1

Hint: Plants have a more definite shape. Animal cells can take various forms from ovoid or spherical. Animal cells do not have distinct shapes.

Complete answer:
Let us first see what similarities plant and animal cells have. Plant and animal cells are eukaryotic cells, and they have some similar characteristics, such as presence of cell organelles such as nuclei, mitochondria, and endoplasmic reticulum, and cell membrane.
Now lets us find the solution from the given options-
Animal cells do not have a cell wall. They only have a cell membrane.
A cell wall is an outer layer that is present in plant cells over the plasma membrane. It is a crucial part of the plant cell, as it gives shape, protection, and strength. The cell wall of the plant is made of cellulose.
Animal cells do not have a cell wall. They have a cell membrane that is an essential barrier that separates the inner parts of the cell from the outside environment while also controlling the movement of substances inside and out of the cell.
Plant cells have cell membranes. The cell membrane of plants lies between the cytoplasm of the cells and the cell wall.

Thus, the right answer is option A i.e Animal cells lack cell walls.

Note: Plant cells have a rigid cell wall due to which they have distinct shape and the cell wall surrounds the membrane of the cells. In animal cells, the cell wall is absent.
