The Cell

Cells are the building blocks of life. In these cells there is a thin transparent sheet controls what goes in, and what goes out,this is called the cell membrane. In the middle of everything there is a dark circular spot which is called the nucleus,the nucleus contains the genes and control centre of the cell. The cell also has the watery jelly like substance which has the nutrients and chemicals. The cytoplasm also holds all the cell organelles together. The cell also has mitochondria,which is the part which performs respiration and gives energy to the cell. The cell also has chloroplast and a cell wall,but they are only found in plant cells. The chloroplast makes sugar for the plant and the cell wall protects the plant from getting infections.
