Discuss transpiration and its effects on plants.

Summary Introduction

To discuss: Transpiration and its effects on plants.

Introduction: Plants are non-motile living beings that are capable of producing their own food by utilizing the sunlight and carbon dioxide. They form the kingdom Plantae that includes all the plants, such as trees, shrubs, bryophytes, and pteridophytes.

Explanation of Solution

The loss of water vapor from the aerial plant parts by evaporation is called transpiration. The cuticle is very effective to decrease the loss of water by transpiration. However, only 1% to 3% of the water lost passes directly through the cuticle from a plant. The process of transpiration mainly occurs through the open stomata. Stomata pores provide opening for the loss of water vapor from the plants. The spongy mesophyll has a loose arrangement that offers a larger surface area in the leaf and the larger surface area helps in the evaporation of water.

The effects of transpiration on the plant are as follows:

  • It is responsible for the movement of water in plants. Without transpiration, the water will not be able to reach the leaves in the soil.
  • The process of transpiration helps to cool the leaves and stems...
