Chapter 19, Problem 31E

Summary Introduction

To explain:  The way in which the increase in atmospheric [CO₂] affects plants water consumption.

Concept introduction:

Photosynthesis is a metabolic process, in which plants convert light energy into chemical energy. During the process of photosynthesis, sunlight is used by the cell to convert carbon dioxide and water into glucose and oxygen. In plants, carbon dioxide (CO₂) enters the leaves through stomata – these are tiny pores present on the leaf surface. Then, carbon dioxide diffuses into the site of Calvin cycle reactions, the stroma of chloroplast and the synthesis of sugars begins.
