Structure and Functions of a cell
Cell membrane Cytoplasm
It is the outer lining of the cell which encloses It is the fluid substance that fills the cell. All
all other cell organelles. The cell membrane the cell organelles are suspended in the
also known as the plasma membrane is cytoplasm. The cytoplasm maintains the
semipermeable. It allows only specific osmotic concentration of the cells and prevents
molecules to pass through and blocking others. them from bursting or shrinking.
Cell wall Nucleus
The cell wall is a rigid layer that surrounds the It is a membrane bound organelle, spherical in
plant cells. Plant cell walls are primarily made shape. Most of the activities of the cell is
up of cellulose. It is located outside the cell directed by the nucleus. All the cells in an
membrane whose main function is to provide animal has one complete set of genes in its
rigidity, strength, protection against nucleus. The genetic material DNA help in
mechanical stress and infection. protein formation.
It is darkly stained are in the nucleus, it aids in
protein formation and RNA synthesis.
