Assignment p1
This assignment is based on P1 where I will outline the cells structure and will also portray the main activities of the organelles. The cell is the main structural and functional group of all living organisms. It is the smallest unit of life which is a form of living things, and is often called the building block of life. Cells are grouped together to form tissues which all have specialized functions.

There are many structures to a cell which all carry out different activities. The nucleus is found in every cell in the body and is the largest structure in the cell. The nucleus contains 23 pairs of chromosomes which are arranged from deoxyribonucleic acid (DNA). The Golgi apparatus is also one of the structures found in the cell which is also known as Golgi complex and is an organelle found in most eukaryotic cells. They are present in every cell but is broad in particular in those which synthesize and outlet protein. The protein transport from the endoplasmic reticulum to the Golgi apparatus which are then confined into the membrane-bound vesicles called “secretory granules”. The mitochondria have a “sausage shaped’ format in the cytoplasm. Mitochondria are associated in aerobic respiration where chemical energy is made accessible in the cell. This is the form of ATP, which releases energy when the cell breaks in down. Ribosome is also a structure of the cell which are little granules made up of RNA and protein. The ribosome synthesise proteins from amino acids using RNA as the template. Ribosome also makes protein for use within the cells such as for enzymes needed for metabolism. Ribosomes are also sighted on the outer layer of the nuclear envelope and rough endoplasmic reticulum where they manufacture proteins for export from the cell. Lysosomes are one of the types of secretory vesicle formed by Golgi apparatus. It contains a cross section of enzymes occupied in breaking down atoms of organelles and large molecules. Lysosomes in white...
