Cell Biology
The report will look at and discuss the life process of a cell, the functions of the cell and the cells structure. A cell is the smallest unit of an organism and is the building block of all living things.
Key life processes of a cell
All living things including cells have some life processes in common. There are seven processes that they need to preform to be classed alive. These are:-
1) Movement all living things have movement including plants
2) Respiration the process of getting energy from food
3) Sensitivity this allows the living thing to detect changes in the surroundings
4) Growth all living things grow
5) Reproduction to reproduce and make more living things of the same type
6) Excretion getting rid of waste product
7) Nutrition taking in and using food
Viruses are not known as living like cells as living things require nutrition and viruses do not. A virus is not live; it is unable to absorb nutrients, produce or excrete waste; so viruses attach themselves to living organism known as a host to survive and gain the nutrition they need. They also need the host to be able to move and reproduce as they unable to do this alone. Viruses have to inject its viral DNA into the host cell it has invaded in order to get the host to reproduce for it.
Understanding living cells and distinguishing them from viruses
There are two primary types of cells prokaryotes and eukaryotes. The key difference between the two is that the eukaryotic cells contain
