Plant and Animal cells

Both plant and animal cells have: 

  • Nucleus -  contains genetic material which controls the activities of the cell. 

  • Cytoplasm - most of the chemical reactions happens here, controlled byenzymes. 

  • Cell Membrane - holds cell together. Controls what goes in and out.

  • Mitochondria - most reactions for respiration take place here. 

  • Ribosomes - where proteins are made in the cell.

Plant Cells

Plant Cells have a few extra things:


  •  Cell Wall - It supports the cell and strengthens it. Made of cellulose.
  • Permanent vacuole - contains cell sap, made of sugar and salts.
  • Chloroplasts - photosythesis happens here. They contain a green substance called chlorophhyll.

Yeast and Bacterial Cells

YEAST CELLS!! 

  • Yeast is a single celled organism! 
  • It's a micro-organism 
  • It has a NUCLEUS, CYTOPLASM and a CELL MEMBRANE, surrounded by a CELL WALL. 

BACTERIAL CELLS!

  • They have NO NUCLEUS 
  •  They have a CYTOPLASM AND A CELL MEMBRANE AND A CELL WALL
  • Genetic material floats in the cytoplasm, because there is no nucleus.
