OSMOSiS

to all students form 4 who learnt biology... all of you had learnt about osmosis,right??? Generally, osmosis can occur in 3 conditions which:-

-hypotonic solution
-isotonic solution
-hypertonic solution

before that, all  of u must know what is osmosis? generally, osmosis is totally about WATER.
so, osmosis meaning movement of water molecules from lower concentration of a region to a higher concentration of a region.

bagi adik-adik yang kurang faham penerangan cikgu biologi  anda, di sini ada penerangan yang diharapkan dapat menjelaskan anda,ok?

1st of all,you must know what is hypotonic,isotonic, and hypertonic solution.

hypotonic solutions:-

movement of water molecules from lower concentration to higher concentration.
nama pun hypo-solutions... ia bermakna larutan tu BANYAK AIR dan KURANG LARUTAN.
kepekatannya cairlah senang cerita...

ini apabila hypotonic solution in action with plant cell which then the plant cell become turgid and hard. This process called PLASMOLYSIS.

this is occurs when hypotonic solution in action with animal cell, an erythrocytes. the cell inflates and bursts. this process called HAEMOLYSIS.

Isotonic solutions:-
concentrations of water inside and outside of the cell is the same.
no changing happen in both plant and animal cells.
so,larutan ni BALANCE..

Hypertonic solution:-
movement of water moles from high concentration to the lower concentration.
maknanya SIKIT AIR...easy to say like larutannya pekat...

this is occurs when hypertonic solution within action with a cell sap of a plant cell. this process called DEPLASMOLYSIS

This occurs when hypertonic solution in action on an erythrocyte which then the erythrocytes shrinks
this process called CRENATION

*FOR EXAMPLE:
distilled water and syrup.

distilled water = hypotonic solutions
isotonic drink 100plus = isotonic solutions
syrup = hypertonic solutions
