Chapter 3 cell structure (plant cells (have same organelles (endoplasmic…

- - - - mother cell
        
        2 daughter cells
    - - nuclei
      - mitochindria
      - chloroplasts
    - - more then one cell
        
        division of labor
        
        more efficient
    - - one cell
- - - - carries large molecules
      - Smooth ER
        
        lack ribosomes
      - Rough ER
        
        ribosomes attached
      - stores proteins
    - - Synthesize proteins
    - - groups of dynamic organelles
        
        prominent activity, photosynthesis
    - - stores energy
      - produces ATP
    - - contains organelles
    - - contains primarily water + salt
    - - hold genetic information
  - - - modifies proteins from ER
      - polymerize sugar to polysaccharides
    - - peroxisomes
        
        detoxification of peroxides
      - glyoxysomes
        
        convert stored fat to sugar
    - - clear substance of cytoplasm
        
        composed of
        
        water
        
        enzymes
        
        intermediate products of enzymatic reactions
    - - act as cytoskeleton
        
        support cell shape
    - - involved in structure movement
      - narrower than microtubles
  - - - thin
    - - increased strength between
        
        primary cell wall and protoplast
- - - - vesicles
        
        permit membrane pieces to move
    - - exocytosis
        
        excrete
      - endocytosis
        
        absorb
    - - selective permeability
        
        facilitated diffusion
        
        hydrophilic channels
      - impermiable
        
        nothing passes
  - - - monolayer
      - bilayer
    - - contribute to cell fluid
      - form complex domains
      - intrinsic proteins
        
        immersed in lipid bilayer
      - extrinsic proteins
        
        outside membrane
      - glycoproteins
        
        polisaccharids bound to protein
