Basic Unit Of Human Body or Cell

Cells are the basic buildings of all living things or the basic structural and functional unit of the human body.

In common mean can say that these are like small pors.The human body composed of trillion cells. They can replicate independently and are often known as the buildings of life. The human body consists of six major systems and the study of every system starts from the cell because the cluster of cells are formed tissues the combination of tissues makes organ cluster of organ makes organ system and organ system combines with one another to form an individual.

The cell body contains different organelles that perform their own functions.

The organelles contain;

Nucleus

Mitochondria

Golgi body

Endoplasmic reticulum

Smooth endoplasmic reticulum

Rough endoplasmic reticulum

Cytoskeleton 

Cell membrane

  Cytoplasm 

Lissome 

Centrosomes 

Vacuoles 

Nucleolus

Chromosomes 

Cell Membrane:

Cell membrane is an outer covering of cytoplasm. It protects the cytoplasmic organelles and also protects the cell from macromolecules. Cell membrane permits the macro as well as micro molecules to come in or come out from the cell. It is also called the protecting wall of the cell.

Chromosomes:

Two different kinds of genetic material are exist Deoxyribonucleic acid [DNA] and Ribonucleic acid [RNA].cells used DNA for their long term information storage. Biological information contain in an organism encoded in DNA sequence.RNA is used for information transport it contain different types such as mRNA, tRNA, rRNA.

The human body contains 44 sex chromosomes containing the pair of 22 from man and 22 from women these are locate in chromosomes.

Nucleus:

It is the main organelle performs the major role in cell body. Nucleus controls the cell activities this organelle is used as the brain of the cell. Nucleus contains dark liquid called as nucleolus. Nucleus locates in the center of cell. The chromosomes also locate in nucleus.
