Introduction
Cells contains a number of organelles which are present either in nucleus, cytoplasm or on the surface and perform different functions.
Pre-Requisites:
What is the structure of a cell and function of different parts of a cell
Activity:
Cheek cells or section of leaf under microscope.
Real Life Question:
How is a cell capable of performing more than one function at a time?
