Life and Cells.

Plant and Animal Cells have Similarities and Differences.

Most human cells, like animals cells have the following parts:

  • NUCLEUS - Contains genetic material that controls the activities of the cell.
  • ENZYMES - Found in Cytoplasm, speeds up and controls chemical reactions.
  • CYTOPLASM - Gel-like substance where most of the chemical reactions happen. It contains Enzymes that control these chemical reactions
  • CELL MEMBRANE - Holds the cell together and controls what goes in and out. 
  • MITOCHONDRIA - These are where most of the reactions for respiration take place. Respiration releases energy that the cell needs to work.
  • RIBOSOMES - These are where proteins are made in the cell.
