Cell Biology, Obrázek1 - Coggle Diagram

- - - - detect changes in external environment
      - immobilized enzymes
        
        catalyze reaction
        
        cell adhesion
        
        tights cells together
        
        comunication
        
        passive transport
        
        protein chanel
        
        active transport
  - - - 1950s - freezed bilayer -cut in the middle - false
        
        Singer-Nicolson model
  - - - Diffusion of water molecules
- - - - First used the term cell
    - - Discovered sperm, blood cell, protozoa etc.
    - - Nucleus
    - - State that cells ure the smallest units of life
    - - cells are araise ba deviding other existing cells
    - - Spontaneous abiogenesis is bullshit
    - - Cells araise from pre-existing cells
  - - - keeping internal conditions optimal
  - - - embryonic cells
        
        +can differentiate to anything and s lot faster
        
        -higher chance of cancer, the embryo is killed
      - Umbilical Cord blood cells
        
        +easy to obtain and store, lower chance of cancer
        
        -storage can be expensive, limited differentiate capacity
      - Adult cells
        
        +full copatible with pacients tissues
        
        -less growth potential, difficult to obtain
  - - - NNN=volume
      - NN6=surface
- - - - organisms occured
        
        Spontaneous abiogenesis refutet
    - - organisms did not occur
- - - - G1
        
        S
        
        G2
        
        preparation for mitosis
        
        DNA replication
        
        increases number of organelles
    - - Prophase
        
        Metaphase
        
        Anaphase
        
        Telophase
        
        chromoseomes on opposite poles-microtubules break down
        
        nuclear membrane begin to form
        
        chromosomes invisable
        
        Chromatide so the opposite poles
        
        chromatide is now chromosome
        
        microtubules fully develop & attach to the centrioles
        
        sister chromatid pair - randomly orientated
        
        Chromosomes become visable - nuclear membrane dissapear
        
        centrioles to the opposite poles
    - - physical diveding into 2 cells
        
        animal cell
        
        plasma membrane pinches
        
        2 cells
        
        plant cell
        
        cell plate forms membrane, vcuole realeses celulose needed for the wall
    - - cells undergoing mitosis / totalN of cels
  - - - primary
        
        cancerous spread to other body regions
        
        secondary tumor
    - - mutagenes
        
        DNA mutation caused by external factor
        
        causes no demage
        
        influences cell cycle
        
        carcinogene
        
        Oncogene
        
        specific genes causing cancer
