 What is osmosis? Definitions and types

Introduction

We know that  all organelles in a cell are compressed in a cell wall. There are more transportation going on a cell that we don't know. So let's see about osmosis in this session.

Shipment

Let's  imagine that you are filling air in football. How do you fill it. Yes absolutely right, with the help of a pump. You can see that it will not pump automatically. You need some energy to push and pull it. In the same way the cell wants to allow something or remove something. They need energy. How does the energy used ? In the form of ATP ( Adenosine Triphosphate ) There are two types in Transportation. Active Transport and Passive Transport. Till now we saw about Active Transportation. Next we can go for Passive transportation

Passive Transportation

Passive Transportation doesn't need any energy. So it is called diffusion. Active needs Energy whereas passive needs no Energy. Ok let's go to osmosis.

Osmosis

Osmosis means movement of water from higher concentration to lower concentration through Semi permeable membranes. 

Examples of osmosis

 

Take a cup of water, put some raisins or black raisins in water. After some time you can see that the raisins start to bulge . This occurs due to osmosis. The water from the cup enters the raisins which cause it to bulge. 

Water during Osmosis

Take three containers and fill it with salt solutions with different concentrations. Add some RCB cells. You can see that the first container of RCB will be shrinking. Second container remains the same. Third container of RCB will be bulged.

Hypertonic solutions

The concentration of salt is high and Water is low. So that is the reason that the first container that contains RCB starts to shrink. This is called as Hypertonic Solutions.

Isotonic solutions

In the second container that contains salt and RCB are both concentrated. They both have equal concentration that is the reason for remains the same. This is called Isotonic solutions.

Hypotonic solutions.

This contains higher water concentration and low concentration of salt . This is the reason for  swollen cells.This is called as hypotonic solution. 

Conclusion.
