Biology - Living Things / Animal and Plant Cells / Food

1. Biology - Living Things

   • Seven Characteristics of Living Things
     • Movement
       • from place to place
       • growing towards light
       • opening/closing petals
     • Respiration
       • release of energy from food
     • Sensitivity
       • reaction to stimuli
     • Feeding
       • making food
       • eating
     • Excretion
       • getting rid of wastes from the body
     • Reproduction
     • Growth
     • MRS. FERG
   • Animal Groups
     • Vertebrates
       • No backbone
     • Invertebrates
       • Fish
       • Amphibians
       • Reptiles
       • Birds
       • Mammals
   • Plants
     • fixed in one position
     • make their own food

2. Animal and Plant Cells

   • All cells have:
     • Cell membrane
       • thin skin that holds cell together
       • controls what can enter and leave the cell
     • Cytoplasm
       • watery fluid in which other structures are suspended
     • Nucleus
       • 'brain' of the cell
       • controls cell's activities
       • controls how cells divide to form new cells
     • Small Vacuoles
       • used for temporary storage of food and waste
   • Plant cells also have:
     • chloroplasts
       • contain chlorophyll
     • cell wall
       • outside membrane
       • gives cell support
       • all plant cells have walls so whole plant wont collapse
     • Large Vacuole
       • stores water, sugar and wastes
         • sugar stored in form of starch
   • The Microscpe
     • eyepiece
     • stage
     • objective lens
     • focus knob
   • Cell Organisation
     • Cell type →
       • Muscle cells
         • Allow movement
       • Red blood cells
         • Carry Oxygen
       • White blood cells
         • Defend against disease
       • Nerve Cells
         • Carry messages
     • Function ↓
   • Tissues, Organs and Systems
     • a tissue is a group of similar cells with a special function
     • an organ is a group of different tissues that work together to carry out a special function
     • A system is a group of organs working together
   • Cell Division and Growth
     • Growth is due to cells dividing

3. Food

   • A balanced diet
     • contains the right amounts of each of the six different food types
   • Food Types
   • The Food Pyramid
     • [Image: http://www.whale.to/a/food_pyramid.gif]
   • Food Tests
   • Food and Energy
     • The amount of energy needed by a person depends
       • Age
       • Gender
       • Activity Levels
       • Health
