Chapter 44, Problem 9RQ

Summary Introduction

To diagram:

The structure of a leaf.

Introduction:

The plants require sunlight for the derivation of the food in terms of stored chemical energy. The leaves are the organs, which traps the sunlight. The transpiration also occurs along with the process of photosynthesis. The plants through self-shading and architectural design manage the water loss and effective sunlight trapping.

Summary Introduction

To determine:

The structures that regulate the water loss and ${\text{CO}}_{\text{2}}$ absorption by a leaf.

Introduction:

The water is required continuously to the plant because the water is regularly lost during the process of transpiration. In addition, the carbon dioxide is absorbed for photosynthesis.
