Science

• how you determine whether something was living or non-living


  To be living it should grow and develop, use energy, reproduce, be made of cells, respond to its environment, and adapt.
• what are the seven life processes

  movement, reproduction, sensitivity, nutrition, excretion, respiration and growth.
• What is a cell


  In biology, the smallest unit that can live on its own and that makes up all living organisms and the tissues of the body.
• What is a unicellular organism?


  Organisms that consist of just one cell are known as unicellular or "single-celled" organisms. They include amoebas, bacteria and yeast.
• Amoeba

  Looks

  A description of the role this organism plays in nature


  A tiny blob of colourless jelly with a dark speck inside it

  
  

  Warm fresh water, such as lakes and rivers.

  Geothermal (naturally hot) water, such as hot springs.

  Warm water discharge from industrial or power plants.

  Untreated geothermal (naturally hot) drinking water sources.

  
  

  Amoebae are essential components of aquatic and terrestrial ecosystems and play a vital role in the dynamics of microbial communities, nutrient cycling, and energy flow
• the definition of a tissue.

  A group of similar cells that are joined together
• what is formed when a group of tissues join together to perform a specific function.

  An organ
• the levels of organisation in the body.

  Higher levels of organization are made from lower levels so molecules combine to form cells, cells combine to form tissues, tissues combine to form organs, organs combine to form organ systems, and organ systems combine to form organisms
• Organ definition

  A collection of tissues that structurally form a functional unit specialized to perform a particular function.
• Tissue definition

  A group of cells that have similar structure and that function together as a unit.
• Cell definition

  The smallest unit that can live on its own. Cells make up all living things.
• Eye piece lens


  This is the lens closest to the eye; it usually has a magnification of x10.
• Objective lens

  Lens of different strengths that magnify the image of a specimen
• stage


  where the slide is placed
• stage clip

  holds the slide in place on the stage
• Diaphragm


  controls the amount of light reaching the slide.
• light source


  A mirror or a light that shines light up through the hole in the stage to illuminate the specimen.
• coarse focus


  used to focus the image to see it more clearly
• fine focus


  used to focus the image so the it is very sharp and clear
• arm


  holds lens above stage
• Base


  very heavy to prevent the microscope falling over
• Cell wall


  Thick rigid membrane, surrounding cell.
• Cell membrane


  thin layer of protien and liquids, that surrounded the cell, but just under the cell wall wall. It allows some things to enter and leave the cell, semipermeable membrane.
• Vacuole


  a large sack of water surrounded by a membrane
• Cytoplasm


  jelly like material, that surrounds the nucleus, in which most of the organelles are found.
• Chloroplast

  Contains chlorophyll, the place where photosynthesis takes place - sunlight is converted to glucose.
• ribosomes


  protiens made here
• Nuclear membrane

  the membrane surrounding the nucleus
• How small are cells compaired to other small objects

  Cells are very small

  they are smaller than a grain of salt but are bigger than atoms and viruses.
• Nucleolus

  ribosomal RNA made here
• nucleus


  controls, many functions of the cell. Contains DNA in chromosomes.
• Mitochondrion


  converts most energy stored in glucose into ATP for cells to use.
• the 6 kingdoms

  animals, plants, fungi, bacteria, archaea and protists
• lysosomes


  round organelle surrounded by a membrane and containing digestive enzymes, which is where the digestion of cell nutrients take place,
• Animal Cell compared to Plant cell

  Plant cells have a cell wall, as well as a cell membrane. In plants, the cell wall surrounds the cell membrane. This gives the plant cell its unique rectangular shape. Animal cells simply have a cell membrane, but no cell wall.

  
• Animal cell


  An animal cell is a type of eukaryotic cell that lacks a cell wall and has a true, membrane-bound nucleus along with other cellular organelles.
• multicellular organism


  is an organism composed of many cells.
• muscle cell


  used to perform movement. there are 3 types, cardiac, skeletal and smooth.
• Namometre/nm


  a metric unit of length equal to one thousand-
• neuron


  A type of cell that receives and sends messages from the body to the brain and back in chromosomes.
