Happy Learning!😊

This is our first class for this chapter. At the end of it, you will be able to:
1. Define Force.
2. Justify that forces are due to an interaction.
3. Distinguish between Contact and Non- contact forces.
4. Explain various types of Contact and Non-contact forces.

FORCE:

A push or pull acting on a body that tends to change its state of rest or of motion is called a force.
The direction in which the body is pushed or pulled is called the direction of the force.

Forces are due to an interaction: 
Force is the cause and the change in the motion of the object is the effect.

    lesson -cell structure n function ( POST 2)

    Image
    Good morning boys! In the last class we learnt that- . Cell is the basic structural and functional unit of life. .Depending on the number of cells , organisms can be grouped as unicellular or multicellular. . The size of a cell is related to its functions. LEARNING OUT COMES- By the end of this class you will be able to- .name the three basic parts of a cell and state their functions .distinguish between a eukaryotic and prokaryotic cell Today we are going to learn about CELL STRUCTURE .a A typical cell consists of three basic parts : 1 .  CELL MEMBRANE OR PLASMA MEMBRANE - . It forms the outer boundary of the cell, gives shape and size  to the cell. . It only allows certain selected substances to enter or leave the cell ( it is semi-permeable ). . It separates the cells from one another  and also from the surrounding medium. NOTE - In PLANT CELLS and BACTERIA there is an outer wall surrounding the cell membrane ,it is called the CELL WALL. It gives pr...
