In this report i will be writing brief description on the functions of the main cell components of the body cell.

The cell membrane :
is something that lets some things in and some things out of the cell. It is an outer cover for the cell. If the cell membrane was non existences the cell would spill all over the place. Its function is to protect the integrity of the interior of the cell by allowing certain substances into the cell, while keeping other substances out. It is composed of a thin, double-layered sheet of lipids, around the Cell and is a protective membrane layer around every Cell.

Nucleus [pic]
The nucleus is the control centre of a cell. It contains genetic material such as DNA and controls the cell's growth and reproduction. The nucleus also controls the synthesis of ribosomes and proteins in the cytoplasm. it also involved in cell division and stores all the information that is to be transferred to the next generation

Cytoplasm
cytoplasm is a homogeneous, which generally clear jelly-like material that fills cells . The cytoplasm consists of cytosol and the cellular organelles , except the nucleus. The cytoplasm offers support for the cell. It allows the cells organelles to freely move throughout the cell. Movement is sped up in the fluid of the cytoplasm. The cytoplasm can also act as a medium for transport within the cell.

Mitochondria: [pic]
The mitochondria is the powerhouse of the cell it provides energy to the cell through respiration.The food that we eat is broken into simpler molecules like carbohydrates, fats and etc in our bodies. These are sent to the mitochondrion where they are further precessed to produce charged molecules that combine with oxygen and produce Adenosine TriPhosphate (ATP) molecules. This entire process is known as oxidative phosphorylation.Mitochondria also helps in the building of certain parts of the blood, and hormones like testosterone and estrogen. Smooth and rough endoplasmic reticulum...
