Structure of Stomata What are Stomata? When a leaf is examined under the microscope, we observe many tiny pores, which are collectively called stomata. Stomata are the minute openings, generally found in the epidermis of leaves. They are typically found in plant leaves and can also be found in stems and other parts of plants . Stomata play an important role by permitting the movement of gases such as oxygen, carbon dioxide, and water vapour to diffuse between the interior and outer surface of the plant tissues. Types of Stomata There are different types of stomata and they are mainly classified based on their number and characteristics of the surrounding subsidiary cells. Listed below are the different types of stomata. Anomocytic Stomata They are surrounded by the epidermal cells, which have a fixed shape and siz...

NUTRITION IN AMOEBA
Process Of Nutrition In Amoeba The different processes involved in holozoic nutrition in amoeba are: Ingestion Ingestion is the process of taking in the food into the body either by swallowing or absorbing it. Amoeba pushes out the pseudopodia to encircle the food and engulfs it forming a food vacuole. This process is known as phagocytosis. Digestion Digestion is the process of breaking the insoluble and large food molecules into soluble and minute molecules. In amoeba, the food vacuoles are transported deeper into the cell and with the help of the digestive enzymes , the large insoluble particles are broken down to the simplest molecules. Absorption In this process of absorption, the nutrients from the digested food material are absorbed into the cell’s cytoplasm by leaving behind the undigested particles. This process is called diffusion. The excess food is stored in the form of glycogen and lipids. Assimilation Assimilation is the process of ob...
