Cell Structure (Cells (Cell Types (Flower Cells (Petal Cells (Pigments…

- - - - Cell division
        
        Produce new protoplasm, absorbs water and salt
    - - Water retention
        
        Cutin and wax are barriers against fungi and insects
    - - Protection
        
        produce poisons that inhibit animals from hardming plants
    - - Collets solar energy by photosynthesis
    - - Collects water and minerals
    - - Transport water, minerals, and organic molecules
    - - Petal Cells
        
        Pigments that attract pollinators
      - Nectary Cells
        
        Sugars that attract pollinators
      - Stamen Cells
        
        Indirectly involved with producing sperm cells
      - Carpel Cells
        
        Indirectly involved with producing egg cells
      - Scent Cells
        
        Fragrances that attract pollinators
    - - Produce sugars, aromas, flavorful compounds that attract fruit-eating/seed-dispersing animals
- - - - hydrophobic
        
        sinks protein to associate with fatty acids
        
        types of proteins
        
        peripheral proteins
        
        outside membrane or next to
        
        intrinsic proteins
        
        partially immersed in lipid bilayer
        
        extrinsic proteins
        
        outside membrane or next to
      - hydrophillic
        
        associates with phospholipid phosphates and water
    - - monolayer
        
        Single layer, hydrophilic ends form hydrogen bonds to water molecules, hydrophobic fatty acids face away from water
      - bilayer
        
        double layer, fatty acids away from water, phosphate group towards water
  - - - helps form membrane, moved and, fuses to growing membrane
      - vesicle lumen
        
        transports material, may be filled with substances that must be accumulated, broken down, or metabolized
      - Exocytosiis
        
        means to excrete, example: nectar
      - Endocytosis
        
        invagination occurs in outer membrane, pinches shut, creating new vesicle.
    - - Selectively permeable membrane (differentially permeable)
        
        certain substances cross more easily and rapidly
        
        more permeable to hydrophobic substances
      - Facilitated diffusion
        
        hydrophilic channels for charged substances
      - Active Transport
