B1.1 cell stucture

• Plant and animal cells are … cells


  Eukaryotic
• Eukaryotic cells have a


  -Cytoplasm

  -genetic material within the nucleus

  -cell membrane
• bacteria are … cells


  Prokaryoric
• Bacteria contain cytoplasm and a membrane surrounded by a cell wall
• Bacteria don’t not have ... or …


  -mitochondria

  -chloroplasts
• Cytoplasm-

  where reactions happen, controlled by enzymes
• Nucleus-

  Controls cells activities
• Cell membrane-

  controls what comes in and out
• Ribosomes-

  where protein synthesis happens
• Mitochondria-


  energy is released here during aerobic respiration
• Large vacuole-


  Contains sap and helps support the cell
• Cytoplasm-

  chemical reactions happen here
• Chloroplasts-


  contain chlorophyll needed for photosynthesis
• Xylem-


  used by the plant to transport water and soluble mineral salts from the roots to the stem and leaves
• Phloem-


  Are tubes used by the plant to transport dissolved food to the whole plant for respiration and storage
• What is cell differentiation?


  During the development of multi celled organis cells differentiate to form specialised cells
• Animal cells differentiate at an early stage

  plant cells retain the ability to special throughout their life
