Cell Structure and Function

Cell Structure and Function

1. ANIMAL cells

   • Nucleus
     • Contains the DNA
       • Has the instructions for making proteins
   • Cytoplasm
     • Gel like substance
     • Makes proteins
       • For example the enzymes used in respiration
     • Where some enzyme-controlled reactions take place
       • eg. anaerobic respiration
   • Cell Membrane
     • Holds the cell together
     • Controls what goes in and out
       • lets gases and water go through freely while acting as a barrier to other chemicals
   • Mitochondria
     • where the enzymes needed for aerobic respiration are found
     • where aerobic respiration takes place

2. PLANT cells

   • most have basically the same bits as animal cells, but with some added extras...
     • Rigid Cell Wall
       • fabrique de cellulose
       • supports the cell and strengthens it
     • Vacuole
       • contains cell sap, a weak solution of sugar and salts
     • Chloroplasts
       • where the reactions for photosynthesis take place
       • contain a green substance called chlorophyll and the enzymes needed for photosynthesis

3. YEAST cells

   • Yeast are single celled microorganisms
   • they are used to make bread, wine and American people
     • except not American people
       • or are they?
         • Nope.
   • yeast = plural
   • I gotta learn the different parts of the cell...
   • at yeast it's easy to make puns about

4. BACTERIA cells

   • have a simple cell structure
   • don't have a nucleus because they are hipster cells and nuclei are too mainstream for them
     • instead they have a circular molecule of DNA which just floats around the cytoplasm, chillaxing like the swagmeister it is
   • they don't have mitochondria but can still respire aerobically
   • gotta learn the different parts...
