Cell types and structured

• What types of cells are animal and plant cells?

  Eukaryotes
• What types of cells are bacterial cells?

  Prokaryotes
• Prokaryotic defenition


  Prokaryotic cells lack a nucleus and a membrane
• Eukaryotic cells defenition 


  Eukaryotic cells have both and nucleus and a membrane
• What are cells?


  The smallest unit of life that can replicate independently
• Cell membrane

  Controls which substances can pass in and out the cell
• Nucleus

  Controls the activities of the cells and contains genetic material(DNA)
• Cytoplasms


  Where chemical reactions take place
• Mitochondria 


  Provides cells the energy they need to function
• Ribosomes


  Where proteins are made
• Rigid cell wall

  Made up of cellulose which helps the cell wall provide support and structure to the cell
• Vacuole 


  Contains cell sap, which is a mixture of sugars, salts and water, that the cell can use when needed
• Chloroplast 


  Where photosynthesis occurs
• What does it mean when a cell is unicellular?

  Single celled
• What to bacterial cells not have?

  Mitochondria, chloroplast, nucleus
• Where do bacterial cells keep their genetic material if not in the nucleus?

  Nucleoid(Circular strand of DNA)
• What do plasmids do(only in bacterial cells)?

  They carry extra genes e.g. antibiotic resistance
• What does a flagella do(only in bacterial cells)?

  Allow the bacteria to move around
• All living organisms are made up of one or more cells
