Most leaves are covered in these tiny pores, which allow the plants to take in carbon dioxide for use in photosynthesis and expel their waste oxygen. The term “stoma” comes from the Greek word for “mouth.” Groups of more than one stoma are often called “stomat...
The primary purpose of stoma is to allow carbon dioxide gas to enter the air spaces in a plant’s tissues. Once inside these air spaces, the CO2can be used by the plant’s photosynthetic tissues as sources of carbon to build sugars, amino acids, and more! The very first photosynthetic organisms had to make all of their biological materials from scrat...
Biologists have used several classification systems to describe different types of stomata. These systems classify stomata based on their placement on plant leaves; based on the structure of surrounding subsidiary cells; or based on the developmental course of the guard cells and subsidiary cells.
