• Parts of a Flower

  • Anther
  • Filament
  • Petal
  • Pollen
  • Sepal
  • Stigma
  • Style
  • Ovary
  • Ovule
• MRS C GREN

  M - Movement

  R - Respiration

  S - Sense

  C - Cells

  G - Growth

  R - Reproduce

  E - Excrete

  N - Nutrition
• Movement (mrs c gren)

  • the movement for all living things/organisms
• Respiration (mrs c gren)

  • the energy that organisms require so that it could move and grow.
• sense - the way an organism refers and responds to its environment.
• Cells - the basic building blocks of all living things, they are the smallest unit of life.
• Growth - the process of increasing in size, especially in relation to the environment, and energy is required to grow.
• Reproduce - creation of a living thing from an existing organism.
• Excretion - the removal of waste products
• Nutrition - obtaining the energy and nutrients (food) needed for growth and development
• PARTS OF A PLANT

  • Leaves
  • Flowers
  • fruit + seeds
  • stems
  • roots
• Photosynthesis - The process by which green plants and some other organisms use light energy to make their food/glucose
• Photosynthesis equation - water + carbon dioxide + sunlight -> glucose + oxygen
• Respiration - The process of transferring energy from glucose to the cell's molecule exchanging gases especially oxygen and carbon dioxide with its environment.
• Chloroplasts - contain chlorophyll, which absorbs light energy for photosynthesis
• Fertilisation is where the pollen and the egg combine.
• the different methods of seed dispersal - Water, wind, animals, explosive
• Materials needed for Photosynthesis

  • sunlight
  • water
  • carbon dioxide
• Diagram of an ATOM

  Neutron - No charge

  Proton - Postive charge

  electron - Negative charge

  Nucleus

  
• Atomic mass = THe sum of proton and neutron
• Proton is the same number as the atomic number.
• Every atom is neutral so the number of electron is equal to the number of proton.
• Explain the gas tests for hydrogen, oxygen and carbon dioxide.

  • hydrogen is very explosive, when it reacts with a lit splint, it pops and makes a squeaky pop noise.
  • Oxygen lights up back up an already glowing splint.
  • Carbon dioxide puts out the fire of a lit splint.
• FORMULA FOR MASS

  m= d x v (Mass = density x volume)
• To find neutron is:

  atomic mass - atomic number  
• Different type of heat transfers

  RADIATION - The process of which energy is. being emitted by either particles or waves.

  
  

  CONDUCTION - When heat energy is being transferred between solid objects by direct contact.

  
  

  CONVECTION - heat transfer occurs in either in a liquid or gas state.

• How does a Gauze mat assist in experiments?

  It helps transfer heat evenly onto the glassware
• What is the purpose of a test tube?

  To remove or evaporate liquids
• What is the primary use of a Bunsen burner?


  To heat substances using a flame
• What is the purpose of a conical flask?


  To mix or hold liquids together
• What is the function of a dropper in the laboratory?


  To collect or dispense small amounts of liquids
