The Fundamental unit of life- Cell, Class 9 Chapter-5
Robert Hooke first discovered cells in 1665 while observing a thin slice of cork under his microscope. He observed that the cork's structure resembled a honeycomb with many small compartments, which he named "cells". A cell is the basic unit of structure and function in living things. Cells can be either unicellular, consisting of a single cell, or multicellular, consisting of many cells. All cells contain organelles that allow basic life functions to occur and specialized cells perform unique functions in multicellular organisms.
