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 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 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.
