… HETEROTROPHIC type of food
• Phagocytosis. Infusoria slipper and common amoeba feed in this way. With the help of pseudopods (Amoeba), it captures food particles by outgrowths of the cytoplasm and forms vesicles around the food, which, mixing with lysosomes, become digestive vacuoles. There, food is broken down to the substances Amoeba needs. Infusoria slipper carries out phagocytosis using the cellular mouth
• Pinocytosis. Absorption of fluid through cytoplasmic outgrowths or special cells.
2. MIXED type of food. Euglena green can receive nutrients from the environment or synthesize them itself. In the case of a heterotrophic type of nutrition, it carries out phagocytosis using the cellular mouth. In the case of an autotrophic type of nutrition (self-synthesis of organic substances), Euglena green has chloroplasts in the cell, where photosynthesis (glucose synthesis) occurs
