Summary Introduction

Introduction:

Plasma membrane is the outer selective barrier that separates the internal component of the cells or organelles from their surroundings. Cells may be macroscopic or microscopic. Cells show a difference in shape and size. Cells work together to perform common functions. Cell consists of different organelles that have different shapes and sizes and perform specialized function. Some of these organelles are membrane bound (enclosed in a membrane), and some are non-membrane bound. Membrane-bound organelles involve any fluid-filled structure surrounded by a membrane. They involve organelles such as Golgi apparatus, endoplasmic reticulum, lysosome, nucleus, and mitochondria.
