LIFE SCIENCE

Detailed explanation-1: -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.

Detailed explanation-2: -In eukaryotic cells, which have a nucleus, the cytoplasm is everything between the plasma membrane and the nuclear envelope. In prokaryotes, which lack a nucleus, cytoplasm simply means everything found inside the plasma membrane.

Detailed explanation-3: -The plasma membrane, or the cell membrane, provides protection for a cell. It also provides a fixed environment inside the cell, and that membrane has several different functions. One is to transport nutrients into the cell and also to transport toxic substances out of the cell.

Detailed explanation-4: -There are many, many types of cells, but there are a few key things most of them have in common: All cells are bound by a plasma membrane. The interior of all cells consists of cytoplasm filled with a jelly-like substance called cytosol. Structures inside the cell are suspended in the cytosol.
