briefly decrib the three essentali parts of a cell of class6
Answers
1. PLASMA MEMBRANE/ CELL MEMBRANE
Structure- a bilipid membraneous layer composed of proteins and carbohydrates. It is fluid like.
Function - the cell membrane separates the cell from its external environment, and is selectively permeable (controls what gets in and out). It protects the cell and provides stability
2.. CYTOPLASM
Structure - The jelly-like substance composed of mainly water and found between the cell membrane and nucleus. The cytoplasm makes up most of the "body" of a cell and is constantly streaming.
Function - Organelles are found here and substances like salts may be dissolved in the cytoplasm.
3.. NUCLEUS
Structure - The largest organelle in the cell. It is dark and round, and is surrounded by a double membrane called the nuclear envelope/membrane. In spots the nuclear envelope fuses to form pores which are selectively permeable. The nucleus contains genetic information (DNA) on special strands called chromosomes.
Function - The nucleus is the "control center" of the cell, for cell metabolism and reproduction.
