Summary Introduction

Introduction:

Plants require water, sunlight and carbon dioxide to perform photosynthesis. There is a waxy covering known as epidermis of the shoot of a plant known as cuticle. It helps to prevent water loss. There are tiny pores on the epidermis of leaves called stomata. They allow carbon dioxide to enter the cell. However, it also lets water to move out from the cell. This is done with the help of guard cells that encloses the stomata.
