Cell Biology and Structure

This statement is false. An animal cell is a form of eukaryotic cell that makes up many tissues in animals.

A plant cell wall is composed of an important substance known as cellulose.

Nucleolus is a non-membrane-bound structure that is composed of proteins and nucleic acids. It is the largest structure in the nucleus of eukaryotic cells, where it primarily serves as the site of ribosome synthesis and assembly.

RER looks rough under a microscope because of the presence of ribosomes.

Cell is the structural and functional unit of a living organism.

The living bodies, which are almost the same in both plant and animal cells are termed as organelles. Centrosome is found only in animal cells. Hence, it is not called as organelle.

Teh cell wall remains present only in plant celsl. It is totally absent in animals.

Mitochondria is known as the power house of the cell. It is a seat of aerobic respiration.

Plastid is a living part of a cell.

Endoplasmic reticulum is continuous with the cell membrane on the outside and the nuclear membrane on the inside. It is the supportive framework of a cell.

Red blood cells are circular and biconcave for easy passage through blood capillaries.

Nerve cells are the longest cells in nature.

Lysosomes are known as suicidal bags. They digest cartilages during the formation of bones.

They store water and other substances like food, pigments and waste products. They provide turgidity to the plant cell.

These are spindle-shaped structures present in planktonic bacteria. They provide buoyancy to these cells by decreasing their overall cell density.
