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...
Structure of Chloroplast
Chloroplast Definition “Chloroplast is an organelle that contains the photosynthetic pigment chlorophyll that captures sunlight and converts it into useful energy, thereby, releasing oxygen from water. “ What is a Chloroplast? Chloroplasts are found in all green plants and algae. They are the food producers of plants. These are found in the guard cells located in the leaves of the plants. They contain a high concentration of chlorophyll that traps sunlight. This cell organelle is not present in animal cells. Chloroplast has its own DNA and can reproduce independently, from the rest of the cell. They also produce amino acids and lipids required for the production of chloroplast membrane. Structure of Chloroplast Chloroplasts are found in all higher plants. It is oval or biconvex, found within the mesophyll of the plant cell. The size of the chloroplast usually varies between 4-6 µm in diameter and 1-3 µm in thickness. They are...
