⇒ All living cells have the same structural organisation with a few changes in plants and animals cells. The basic structure of a cell includes a cell membrane or plasma membrane, cytoplasm and nucleus.

⇒ Cell membrane or plasma membrane :- It is a thin, elastic membrane surrounding the cell. It protects the cell and it a shape. It is semipermeable, which means it selectively allows the materials to go in and out of the cell. All the material of the cell that is enclosed by the cell membrane is called the protoplasm.

⇒ Cell Wall :- It is present only in plant cells. It is an extra layer present outside the cell membrane. Plants are fixed in one place, have to face unfavourable conditions and do not have any skeleton for support. The cell wall provides rigidity and protection to the plant cells. It is made up of cellulose.

Answer:

Cell Structure.A cell consists of three parts: the cell membrane, the nucleus, and, between the two, the cytoplasm. Within the cytoplasm lie intricate arrangements of fine fibers and hundreds or even thousands of miniscule but distinct structures called organelles.
