2 thoughts on “Explain main functional regions of the cell with the help of a diagram”
Answer:
The 3 major parts of the cell are : Plasma Membrane – the outer covering of the cell that encloses the cytoplasm. Cytoplasm – the jelly like matrix within the cell that contains the various organelles. Nucleus – round and usually centrally placed structure that controls the various activities of the cell.

Answer:
the cell is the structure and functional unit of Living Organism
the three main functional regions of cell are cell wall, nucleus and cytoplasm
cell wall
it is found around cells of algae fungi and plants animal.
cell wall is an elastic and strong goat around cell membrane .
it is mainly composed of Carbohydrates like cellulose and pectin afterwards polynomials like Lignin sabran cutin added in cell wall as per need.
cell membrane.
cell membrane is also known as plasma membrane.
it is a thin and Elastic covering that separates the cell components from outer environment.
plasma membrane is said to be selectively permeable membrane as it allows some substance to enter the cell while prevents other substance .
useful molecules of water salt and oxygen enter the cell and CO2 exist the cell
nucleus
nucleus is covered by a double membrane with small pores .
these pores allow the passage of materials in and out of the nucleus.
nucleus has one round nucleolus and a network of chromatin fibres .
chromatin fibres are thin thread like structures which condense to form sorter chromosomes at the time of cell division.
cytoplasm
cytoplasm is the fluid between plasma membrane and nucleus.
it is moving sticky substance.
many cell organelles are suspended in cytoplasm.
cytoplasm is the medium for cellular chemical reaction .
the part of cytoplasm other than organelles is a cytosol.
