All living organisms - plants, animals and human beings are made of small structures called cells. Learn about the discovery of cell, different cell theories and the Invention of microscope.
Based on cell number organism are classified as Unicellular(single celled) and multicellular(more than one cell) organisms. The hierarchy level of organisation is : cell -> tissue -> organ -> organ system -> organism.
Understand the Shape, size and components of cell, cell organelles and it functions and the difference between animal cell and plant cell
Transportation of substances in and out of the cell takes place by diffusion and osmosis
Diffusion: Movement of molecules from a region of higher concentration to the region of lower concentration is called diffusion
Osmosis- diffusion of water across a semipermeable membrane is called osmosis.
Types of osmosis based on the concentration of solution are:
hyper tonic solution - plasmolysis
hypotonic solution - endosmosis
