Cell is functional unit of life. These chromosomes are made up of DNA and proteins. The reason being the concentration of cell and a solution is the same. Ans: Proteins are made by ribosome and lipids by SER. There are segments of DNA that are responsible for characters in a body or transfer of characters from parents to offspring and are called genes. In Latin cell means small compartments. 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. Osmosis 2. If we study about the hierarchy then we will notice that the level of organization is : That means that the smallest unit of body is cell. The Fundamental Unit of Life CBSE Class 9 Science Chapter 5 - Complete explanation and Notes of the chapter 'The Fundamental Unit of Life'. Every organism starts life as a single cell. Cell is often referred as “structural and functional unit of living organisms”. The cells having well organised nucleus are called............ 7. Let us study them in detail: There are many types of organelles that help the cell in performing different functions. This chlorophyll is present in organelle chloroplast. They are present in plant as well as in animal cell. Q11. The reason is that the cell is the smallest unit of body and directly or indirectly, it is responsible for functions also. Take four peeled potato halves and hollow each one out to make potato cups .One of these cups should be made from a boiled potato .Put each potato cup in a trough containing water .Now. Transportation of substances Endoplasmic reticulum helps in formation of membrane of cell .That is : They can remove worn out parts of the cell. These enzymes can carry out the catabolic function.

The shape can be fixed or can be variable. It   provides mechanical support to cell. This chlorophyll actually helps in capturing solar energy and converting it to chemical energy of food. Spindle fibres 2. As you all know the body of an individual is of complex type. Nuclear membrane: -It is the membrane that separates the nucleus from the cytoplasm. It maintains the osmotic pressure of cell. These organelles perform necessary functions for the cell like some organelles help in cleaning the cell, some help in synthesizing certain substances for the cell, some perform catabolic function like breakdown of food, etc. It contains genes that help in transmission of characters from parents to offspring .
