Cells

Eukaryotes and prokaryotes 

Eukaryotes- 

• Includes all plant and animal cells
• Often complex

Prokaryotes-

• Single celled organisms
• Smaller and simplier that eukaryotes 
• Includes bacteria cells

Animal cells: 

• Nucleus = genetic material
• Mitochondria = most aerobic respiration takes place, the powerhouse of the cell
• Ribosomes = where proteins are made
• Cell membrane = holds the cell together and controls whay goes in and out
• Cytoplasm = where most reactions takes place

Plant cell

• Has usually all the other parts that animal cells have
• Chloroplasts = where phtosynthesis takes place, contains a green substance which absorbs the light needed for photosynthesis 
• Vacuole = contains cell sap, a weak solution including sugar and salts
• Cell wall = made out of cellulose, supports and strengthens the cell

Bacteria cells

• Cell wall
• Cell membrane
• Cytoplasm
• No chloroplasts or mitochondria
• Don't have a true nucleus - instead they have a circular strand of DNA that floats freely in the cytoplasm
• They may contain one or more small rings of DNA calls plasmids

Microscopy

• Microscopes allow us to see things we can't already see with our eyes
• Light microscopes use light microscopes use light and lenses to form a image of a specimen and magnify it.…
