Vedclass · Answer

(C) $\Rightarrow$ $A$ cell is the fundamental structural and functional unit of all living organisms.$\Rightarrow$ All physiological and biochemical processes within an organism depend on the structure, type, and number of cells present. Thus, the cell is the basic unit of life.$\Rightarrow$ The life of every multicellular organism begins from a single-celled structure called the $Zygote$. New cells are generated through the repeated division of this $Zygote$.$\Rightarrow$ These cells subsequently differentiate to form tissues, organs, organ systems, and eventually the entire body of the organism.$\Rightarrow$ $Totipotency$: It is the ability of a single cell to divide and produce all the differentiated cells required to form a complete organism.$\Rightarrow$ Historical Context:$\Rightarrow$ $Anton$ $van$ $Leeuwenhoek$ was the first to observe and describe a living cell.$\Rightarrow$ $Robert$ $Hooke$ $(1665)$ observed a thin slice of cork under a microscope. He described the honeycomb-like structures as 'cells'.$\Rightarrow$ $Robert$ $Brown$ $(1831)$ discovered the nucleus. The subsequent invention and improvement of the microscope, leading to the electron microscope, revealed the complex structural details of the cell.
