Question

Sketch and describe in your own words, the animal cell

Answer 1

• Cell membrane: A cell is composed of cell membrane, cytoplasm and nucleus. The cytoplasm and nucleus enclosed in the cell membrane together constitute the plasma membrane. It checks the transport of substances in the cell.

• Plasma membrane

• Cytoplasm: It is a jelly-like substance present between the cell membrane and nucleus. It contains various cell organelles such as mitochondria and Golgi body.

• Nucleus: It is a dense spherical body located at the centre of the cell. It is surrounded by a porous nuclear membrane. It contains a spherical body called nucleolus and thread-like structures called chromosomes. Chromosomes are the structures that carry genes and play an important role in inheritance. The entire living substance in a cell is known as protoplast.

• Vacuoles: Vacuoles are fluid-filled membrane-bound structures in the cell. In animal cells, numerous small vacuoles are present.

• Mitochondria: They are involved in cellular respiration, and hence, are called ‘power houses of the cell’.
