Cells - Coggle Diagram

- - - - Prokaryotic cells
      - They have a large circle of DNA
        
        Bacterial DNA
      - Have smaller circles of DNA
        
        Plasmids
- - - - A group of different tissues that carry out a function together
      - Animal examples
        
        Stomach, heart, kidneys
      - Plant examples
        
        Leaf, onion bulb
      - Organ system
        
        Several organs that work together to perform a particular function
        
        Digestive system, circulatory system, excretory system
  - - - Moves mucus in the trachea and bronchi of animals
    - - Absorption of Water and mineral ions in the roots of plants
    - - Phtotsynthesis in the leaves of plants
    - - Conduction of electrical impulses
    - - Transporting oxygen in blood
    - - Reproduction
- - - - Eyepiece
      - Focussing knob
      - Objective lenses
      - Stage (Where specimen Is placed)
      - Mirror (reflects light up through the specimen)
    - - 1500x magnification
      - A photograph taken by it is a photomicrograph
    - - 500000x magnification
      - Electron micrograph
        
        Image taken by an electron microscope
- - - - A very thin later of protein and fat surrounding the cytoplasm of every cell; it controls what enters and leaves the cell
      - Partially permeable
        
        lets some substances through but not others
    - - Made mainly of cellulose
      - Tough later outside the cell membrane; found in the cells of plants, fungí and bacteria
      - Fully permeable
        
        even very large molecules are able to go through
    - - Jelly-like material that fills a cell
      - It is nearly all water
      - Many substances disolved in it, specially proteins
      - Many metabolic reactions take place here
    - - Fluid-filled space inside a cell
      - Separated from the cytoplasm by its own membrane
      - Plant Cells have large vacuoles
        
        The vacuole contains solutions and cell sap
        
        Cell sap presses outwards and helps the cell keep its shape
      - Animal Cells have smaller vacuoles
        
        Also contain solutions
    - - Where genetic information Is stored
      - information stored on chrompsomes
        
        made of DNA
        
        DNA determines which proteína are made
    - - Never found on animal cells
      - Contain clorophyl
        
        Absorbs energy from sunlight
        
        Photosynthesis
      - Most Cells in green parts of plants have them
      - Contain starch grains (result of photosynthesis)
        
        Tiny pieces of starch
    - - Can only be seen with an electron microscope
      - Found in almost all plant and animal cells
      - Where aerobic respiration happens
        
        Energy obtained from glucose
        
        Main way in which cells stay alive
      - Where cells produce energy
    - - Tiny structures found in almost all plant and animal cells
      - Can only be seen with an electron microscope
      - Where proteins are made
        
        Using DNA information
