  • The 7 life processes
    • Movement
    • Respiration
    • Sensitivity
    • Growth
    • Reproduction
    • Excretion
    • Nutrition
  • Movement
    The ability of organisms to move, a change of position
  • Movement
    • Move from place to place
    • Move parts of themselves
  • Reproduction
    Organisms can make more living things like themselves
  • Things plants do to reproduce that animals do not
    • Make seeds
    • Make fruit
    • Use insects for pollination
  • Sensitivity
    The ability to detect and respond to changes in the internal and external environment
  • Sensitivity
    • Changes in temperature
  • Growth
    Living things increasing in size
  • How trees grow
    They continue to grow
  • How humans grow
    They stop growing after a while
  • Respiration
    A set of chemical reactions that release energy for metabolism
  • How fish get oxygen
    They get it from water
  • How humans get oxygen
    They get it from air
  • Excretion
    The removal of waste products of metabolism, substances in excess of requirements
  • Nutrition
    Taking in of materials for energy, growth and development
  • Systems of the human body
    • Digestive system
    • Circulatory system
    • Nervous system
    • Urinary system
  • Digestive system
    1. esophagus (gullet)
    2. Stomach (breaks down food)
    3. Small intestine (breaks up food and absorbs it)
    4. Large intestine (removes water from unwanted food)
    5. Liver (makes, stores and destroys substances)
  • Circulatory system
    1. Heart (pumps blood)
    2. Blood vessels
    3. Blood
  • Nervous system
    1. Brain
    2. Spinal chords
    3. Cranial nerves
    4. Spinal nerves
  • Urinary system
    1. Bladder (stores urine)
    2. Kidneys (clean blood and produce urine)
    3. Rectum (stores waste materials)
  • Heart tissue
    • Whiter parts are fat, reddish parts are muscle
    • Fat tissue helps to protect heart
    • Muscle tissue pumps blood
  • Root tissues
    • They have hairs on the outside to help the roots take water out of the soil quickly
  • Xylem tissues in carrots
    • They carry water up from the roots through the carrot and on into the rest of the plant
  • Leaf
    • Traps sunlight to make food for the plant
  • Stem
    • Carries substances around the plant and supports the leaves and flowers
  • Root
    • Holds the plant in place
    • Takes in water and small substances from the soil
  • a microscope is used to magnify a specimen to see structures which cannot be seen with the naked eye
  • stage
    • platform to place the slide
  • total magnification= magnification of eyepiece lens x magnification of objective lens
  • eyepiece lens
    • to look at the specimen
  • objective lens
    • for greater magnification
  • coarse focus knob
    • to bring the specimen to focus
  • fine focusing wheel
    • helps the image focus
  • bladder
    • stores urine
  • kidneys
    • clean the blood and produce urine to excrete wastes
  • liver
    • makes and stores some substances, and destroys other substances
  • lungs
    • get oxygen into the blood for respiration, and excrete carbon dioxide
  • large intestine
    • removes water from unwanted food
  • small intestine
    • breaks up food and absorbs it, to provide nutrition for the body
