Match the statement in column A with those in Column B. S.No Column A S.No Column B 1. Cell (a) Plant cells 2. Nucleus (b) Tiny structures inside cells 3. Cell wall (c) Unit of living body 4. Chloroplast (d) Boss of the cell 5. Cytoplasm (e) Green pigment present 6. Organelles (f) Jelly-like substance between cell membrane and nucleus

1. A cell is the structural and functional unit of a living body. It helps in the formation of the tissue, organ, and the structure of an organism. 2. Nucleus controls all the functions of a cell, so called the boss of the cell. It contains the hereditary material called chromosomes. 3. Cell wall is present in the plant cells, and they are made up of cellulose. It provides rigidity and support. 4. The plants contain a green coloured pigment called chlorophyll. Chlorophyll is the green pigment present in chloroplast. This helps in the process of photosynthesis. 5. The cytoplasm is the jelly-like substance present within the cell membrane and out of the nucleus. In this cell-organelles are found. 6. Organelles are the tiny structures inside the cell, like mitochondria, Golgi complex, ribosomes, etc. S.No Column A S.No Column B 1. Cell (c) Unit of living body 2. Nucleus (d) Boss of the cell 3.

Cell is the structural and functional unit of life. It is discovered by the scientist called Robert Hooke in 1665. The components of cell are cell membrane, nucleus, and cytoplasm. It contains a jelly-like structure which contains many organelles such as, mitochondria, chloroplast, nucleus, Golgi complex, ribosomes etc.
