Cells - Coggle Diagram

- - - - animals and plants
  - - - •Each living cell consists of living material called
      - protoplasm which is contained within the cell
      - membrane.
      - •The protoplasm is made up of 70% water and
      - 30% of other substances, most of which are
      - proteins, carbohydrates and fats.
      - •The composition of protoplasm varies greatly
      - from cell to cell.
  - - - animal cell
    - - plant cell
    - - cell surface membrane
        
        partially permeable
        
        A partially permeable membrane is like a
        
        guarded door that allows only some substances
        
        to cross it.
        
        controls substances going in and out and keeps all content inside
      - cytoplasm
        
        specialised structures called organelles
        
        smooth ER
        
        makes substances such as lipids and steroids (sex
        
        hormones)
        
        converts harmful substances into harmless
        
        materials (detoxification)
        
        rough ER
        
        ribosome attached to rough ER
        
        transports proteins to golgi apparatus
        
        the golgi apparatus
        
        1 more item...
        
        free ribosomes
        
        make protein just for the cell
        
        attached ribosomes make protein for out of the cell
        
        where cell activities occur
      - nucleus
        
        surronded by nucleus envelope
        
        contains genes in form of chromatin
        
        involved in repairing the cell and cell division
      - mitochondrion
        
        double membrane with inner membrane folded
        
        sausage shaped
        
        where respiration takes place
      - only for plant cell
        
        cell wall
        
        fully permeable
        
        made of cellulose
        
        protect from injury and gives structure
        
        chloroplast
        
        only for plant cell that has green
        
        contains chlorophyll
        
        photosynthesis
  - - - one large in plant cell, few and small in animal cell
