Biology all over my face

 With another 2 more days to go, i have to crack my head for Biology tomorrow and Physics on Wednesday. I died halfway during Accounts 2day @_@

Anyway, for those who haven't learn anything about Biology or have no idea what i am about to talk about. i suggest you skip this post because its more about me talking more and more about Biology XD

First off that i always get confused is mostly the Cell division. There are also many more topics that i understand but can;t seem to remember the facts for my exams.

Mitosis and Meiosis
With the stages of changing chromatids and other stuff.
Remembering the Prophase, Metaphase, Anaphase and Telephase.
More of the Spindle fibres forming with the Sister Chromatids splitting and moving towards the pole formed with the centrioles. Then finally done once the Chromatids are in seperate cells when they split.

Thats just the start @_@
Meiosis is a more less almost same like Mitosis. The differences is that Meiosis is for Gamete cells (sex cells, Sperm,Ovum) Where the Chromatids cross over each other and produce Variations when they split like Mitosis. There also loads of other facts to remember like Chiasma the place where the chromatids cross over and Synapsis which i forgot does what =='
I actually just studied it a while ago @_@
Oh Please help me for Biology Paper tomorrow >_>

Now to move on to the few first topics i learn in Form 4!
The Movement of Substances across the Plasma Membrane!

The Phospholipid Bilayer!
Withe the Hydrophilic Head and the Hydrophobic tail.
There are actually other cells on the bilayer itself for the transport of Charged ions, and other things that need to pass through the cells which i can't think of right now ._.
There are Pore Proteins, Carrier Proteins, with other Glycoprotein and Glycofats i think? around the bilayer.


With all this movement of cells, there are also movement of water going down the transportation gradient. Where water diffuses out or in of the cell making the cell lose or gain water.
Isotonic have the same equilibrium amount of water and there is no movement of water.
Hypertonic have a high concentration of solute with low amount of water making water diffuse to the cell or solution that is Hypertonic.
Hypotonic on the other hand has a low concentration of solute with a high amount of water. Water diffuses out from from any Hypotonic cell or solution.


I guess thats all my brain can think of now be4 i go to sleep. i really hope i can do better in my Biology paper tomorrow :/
I must work hard! Must keep revising and remember all the other facts about Bio!! @_@
Meh, Maybe i just need a very BIG BIG motivation xD
