Function system of In Amoeba
Amoeba possesses a holozoic mode of nutrition and process is known as “phagocytosis”. The basic processes involved in the nutrition include:
Amoeba
(Phagocytosis in Amoeba) (Source: Wikipedia)
Ingestion: Amoeba takes in its food through this process. Initially, it pushes out its pseudopodia so that it can encircle the food. After this, it engulfs the food, thus forming a bag-like structure called food vacuole. The process is known as “phagocytosis”.
Digestion: This step follows ingestion. The food vacuoles are rich in various digestive enzymes. These enzymes break down large insoluble foodstuffs consequently yielding simple soluble molecules.
Absorption: It is the process of absorption of the digested food material into the cytoplasm leaving behind the undigested food material. Sometimes the amoeba absorbs large quantities of food. What happens to the excess food? Well, the excess food gets stored in the form of glycogen as well as lipids.
Assimilation: This is the “utilization” process. During this process, the absorbed food is utilized for energy production, growth, repair as well as for multiplication.
Egestion: Finally, the cell membrane gets ruptured so that the undigested food material is thrown out of the body.

Using Water Wisely
Water is life! If there were no water, there would be no life! Let’s broaden our perception about water and see how it is wonderful. Do you know all life forms of all species of flora and fauna are made up of water? Water is the major component of cells, typically forming between 70% and 95% of the mass of the cell. This means 80% of our body mass is water. Not only are we made up of water, it is the only transportation medium that carries the food molecules and oxygen to the cells of every body parts to help the blood. It also helps the body in excreting wastes and toxic substances from cells, tissues, organs and organ systems in the form of sweats and urines. It signifies that water is the most essential ingredient to the functioning of life processes of every organism. So you see living this wonderful life is impossible without water!
Besides being the base of all eating and drinking water is the force behind all the industry, agriculture, manufacturing and trade and commerce. No production of anything is possible without water. There would be no crops, fruits, vegetables, cereals, pulses if water would not give life and form to them! Similarly, dairy industry also flourishes on water.
Now let’s come to the energy production sector. All forms of energy generation is done using water. Be it hydroelectrically projects, or thermal power plant, or nuclear power plant, water is the key ingredient in all of them. There would be no power without water!
In spite of the indispensability of water in our life, our attitude to water is pathetic. We have been abusing its divinity! We have made it scarce. Mismanagement of water resources coupled with careless industrialization and agriculture have further led to colossal water pollution across the nation. Explosion in human population has caused land encroachment in the forest and pasture areas which resulted in desertification and deforestation. Since we the humans have over indulged ourselves with all the resources of this planet without any heed to other earthlings, we have become the worst predators ever!
So, it is our responsibility to conserve this life nectar. It is possible only through by changing our outlook towards this wonderful natural resource. We must ensure there is no pollution of water bodies by dumping any waste such as, sewage, effluents, and other toxic substances. The people and the government must ensure installation of effluents and smoke treatment plants at industrial, garbage, and sewage units. People who use water must use it frugally. Any wastage of this wonder resource must immediately be stopped. At households, shops, agriculture and industries there should be optimal utilization of water.
By being the proactive stewards of this rare life-supporting element can we preserve and conserve it. Students can play a great role in conserving this life-giving nectar by being the volunteers and protectors of water. They can conduct rallies across cities and villages to make people aware of practices that preserve water. The Government must take help of the younger generation to accomplish this gargantuan task.
