Transport in cells - Coggle Diagram

- - - - no net movement of water
    - - water leaves, cell shrinks (crenates)
        
        turgor pressure decreases
    - - water enters, cell swells (lysis)
        
        turgor pressure exerted by vacuole on cell wall
  - - - water enters, cell swells (turgid)
    - - no net movement of water
    - - water leaves, cytoplasm shrinks, membrane pulls away from cell wall (plasmolysed)
- - - - SA to V ratio over which it occurs
      - distance of which it occurs
      - concentration gradient
  - - - channel protein
        
        hydrophilic channel for the ions
      - carrier protein
        
        binds temporarily to the carrier protein
        
        protein changes shape to transport it across membrane
        
        change is triggered by the binding and release
- - - - needs ATP to change shape
    - - allows cells to take up nutrients even if their concentration is higher
      - allows cells to get rid of waste even when concentration outside cell is higher
  - - - make sure you memo process
        
        process
        
        pesdophodias are formed to engulf the particles
        
        the pseudophodias fuse with each other to form a big food vacuole to enclose the particles
        
        take up food by forming food vesicles around foreign particles through phagocytosis
        
        vesicels formed will fuse with lysosomes
- - - - secretory vesicles move towards and fuse with cell membrane
        
        releasing contents of vesicle into fluid around the cell
        
        ATP is used to provide energy during this process
    - - taken into cells by inward folding
      - form secretory vesicles to separate from membrane
      - ATP used in this process
      - examples of endocytosis
        
        phagocytosis
        
        phagocytes engulfing and ingesting foreign particles
        
        formation of pseudopodia to engulf the particles
        
        vesicle will fuse with lysosomes
