🧬 The Cell – The Fundamental Unit of Life | Class 9 Biology

The cell is the basic structural and functional unit of life. All living organisms — from the smallest bacteria to the largest plants and animals — are made up of cells. It is the cell that performs all vital activities such as growth, metabolism, and reproduction.

Cells may exist as a single unit in unicellular organisms like Amoeba, or as millions of specialized cells in multicellular organisms like humans. Each cell has different parts like the cell membrane, cytoplasm, and nucleus, which work together to keep the cell alive and functioning.
