What is a cell?

A cell is the smallest unit and the building block of an organism. All living organism have cells E.G Bacteria, plant, animals and unicellular organisms. A cell contains a nucleus which controls the activity of the cell and contains your DNA, mitochondria where most energy is released, cell membrane which controls what goes in and out and that holds it together, cytoplasm where most chemical reactions occurs  . how ever in a plant cell there are: vacuole which contains a solution of salt and sugar, cell wall the skin around the cell that gives support to the cell and finally chloroplast which is used to make photosynthesis.

There are different types of cells in both animals and plants,these are:

 

ANIMAL                                                                                               PLANT
