P1- outlines the functions of the main cell components.
The human body is organised into five parts:-
Cells form…
Tissues form…
Organs form…
Organ systems/ body systems form…
The human body.

In this assignment I am going to be outlining the functions of the main cell components which include cell membrane, nucleus, chromosomes, cytoplasm, mitochondria, endoplasmic reticulum, Golgi apparatus and lysosome. There are two types of main cells which include eukaryotic and prokaryotic cells. A eukaryotic cell is a human cell. A eukaryotic cell possesses a clearly defined nucleus and has a nuclear membrane that surrounds the nucleus in which the chromosomes are found. There is also another type of cell which is a called a prokaryotic cell, this cell lacks a membrane bound nucleus. The difference between these two cells is that Eukaryotic cells contain membrane-bound organelles, such as the nucleus, while prokaryotic cells do not. Cells are the main building blocks of all living organisms. The human body is collected of tons of cells which provide structure for the body, take in nutrients from food, transform those nutrients into energy and carry out specialised functions. Cells also contain the body’s genetic material and can make copies of them. During the development of a multicellular organism, cells set apart so that they can carry out different functions. The process of the separation of the cells is so that they become a specialised type of cell such as a tissue. A tissue is a group of specialised cells that have a similar structure and function. The human body is much organised. Specialised groups of cells form tissues, tissues form organs, and organs form body systems. An organ is a specialised group of tissues that completes a particular function and sometimes it may complete more than one function. Example of an organ can be the brain, heart, eyes, bones, intestines, pancreas, rectum, ears, stomach, liver, and gallbladder. There are nearly up to 78...
