It is a ppt on fundamnetal unit of life based on a NCERT Chapter 5 of standard 9. For example: Cell respire i.e. Transportation of substances This is because when it is placed in a hypotonic solution, the water from solution moves into cell (endo-osmosis) due to  which cell starts swelling up .The fully swollen cell in which the protoplasm almost touches the cell membrane is called Turgid cell. But at the smallest level, our body is made up of tiny units called cells. So, when there is no water left in them they start to droop. When he saw the internal structure of cork with the help of microscope it looked like compartments .So, earlier these cells were named as compartments but later on it was replaced by term cell.

Where protein synthesis occurs in the cell? * It is living, thin and delicate membrane. How do substances like carbon dioxide and water move in and out from the cell? This is because when it is placed in a hypertonic solution, the water from cell moves into solution (exo-osmosis) occurs due to which cell starts shrinking up .The cell whose protoplasm almost gets shrunk is called flaccid cell. The cell theory, that all the plants and animals are composed of cells and that the cell is basic unit of life, was presented by two biologists, M. Schleiden (1838) and T. Schwann (1839). 5.
