Summary Introduction

To review:

The experimental design to determine the photosynthetic strategy followed by the new species of succulent plant, which has stomata open during the daytime under the mild spring environment.

Introduction:

The process of photosynthesis is categorized on the basis of external environmental conditions into different types. C_3, C₄ and CAM photosynthetic pathways are the modes followed by the plants to make sugars from CO₂. Crassulacean acid metabolism (CAM) is a carbon fixation mechanism mainly evolved in plants of dry and arid conditions. The main feature of these plants is the opening of stomata at night to collect carbon dioxide. The closed state of stomata during daytime prevents the loss of water, thus helps the plant to prevent from desiccation.
