cells

• describe a prokaryotic cell


  - smaller and simpler

  - genetic material not enclosed in a nucleus

  - usually unicellular
• describe a eukaryotic cell

  - bigger and more complex

  - genetic material enclosed in a nucleus

  - usually multicellular
• how is genetic material stored in a prokaryotic cell

  - main circular strand of DNA

  - additional plasmids of DNA (small rings free in cytoplasm)
• name organelles of both animal and plant cells

  nucleus, cytoplasm, cell membrane, mitochondria and ribosomes
• name additional organelles only in plant cells

  cell wall, chloroplasts and permanent vacuole
• what is the function of the nucleus

  contains genetic material and controls cellular activities
• what is the function of cytoplasm

  gel like substance that contains organelles and enzymes and site of most chemical reactions
• what is the function of the cell membrane

  controls substances that enter and exit the cell
• what is the function of mitochondria

  site of aerobic respiration
• what is the function of ribosomes

  site of protein synthesis
• what is the function of the cell wall

  provides support and strength to cell
• what is the cell wall made of

  cellulose
• what is the function of chloroplasts

  site of photosynthesis
• what do chloroplasts contain and why

  chlorophyll (green pigment) to absorb light needed for photosynthesis
• what is the function of the permanent vacuole

  supports the cell to maintain turgidity
• what does the permanent vacuole contain

  cell sap (solution of salts and sugars)
