Summary Introduction

To determine:

How photosynthesis is affected when the stomata close.

Introduction:

The opening and closing of stomata is dependent on influx and out flux of K+ ions. The influx of K+ ions result in increase in ionic concentration allowing the water to move inside the guard cells whereas out flux of K+ ions increases the ion concentration outside the guard cell which makes water to flow out from the guard cells making them shrink and closing the stomata.
