Summary Introduction

To define:

The term diffusion and osmosis and also explain how osmosis helps plant leaves to remain firm. Determine the term for water pressure inside plant cells.

Introduction:

A cell membrane is made of different molecules like phospholipids, proteins, and cholesterol that contribute to the flexible nature of a cell membrane. A cell membrane is selectively permeable in nature which means it allows selective substances to enter the cell. The movement of molecules could be passive like in osmosis and diffusion or could be by active transport or facilitated transport.
