Stomata

Stomata are present on the leaves of plants. They may be found on either sides or side of a leaf. When they are present in both sides, then they are known as amphistomatic. However, if it is present on the upper side then it is called epistomatic; & if found on the lower sides, then they are called hypostomatic. They are positioned in the epidermis of the leaf surface. However, it is fascinating to note that the positioning of stomata is different from plant to plant. Besides the difference in the location, the dicot leaves are known to have more number of stomata on the upper surface than the lower side. However, monocot leaves have the same number of stomata on both the upper & lower side of the leaves.

As a biology student, the most common idea that you will be introduced to initially is the study of cells. The stomata in a cell play a vital role in the system of respiration & photosynthesis. Each & every creation of God is distinctive & important in its own way. They are also connected to each other. Plants & trees are important for our existence as they provide us food to eat, air to breathe, & lots of more things. Stoma is of the most important parts of a plant. It means 'mouth'. In this editorial, they will learn about the various functions of stomata in detail.

The most vital function of stomata is respiration, which is the exchange of gases. Basically put, this refers to the system through which the plant takes carbon dioxide from the atmosphere, & gives out oxygen. This oxygen is utilized by human beings & animals. Another important function is photosynthesis. This is the system through which plants manufacture food taking the help of water, carbon dioxide, & sunlight.

The structure of stomata is also very fascinating to study. It comprises of a kidney formed epidermal cell having an opening at the middle known as a pore. The inner walls of the guard cells countenance the hole & are much thicker than outer layers. The guard cells also have large vacuoles. The cells that surround the guard cells are called the subsidiary or accessory cells.
