The cell is the basic structural and functional unit of any living being. It is the fundamental building block, which when combined with similar cells forms a tissue and organs. A cell comprises several organelles: The cell undergoes a series…
Cell division happens when a parent cell divides into two or more cells called daughter cells. Cell division usually occurs as part of a larger cell cycle. All cells reproduce by splitting into two, where each parental cell gives rise…
Q1 What is Aerobic Respiration? Aerobic respiration is the burning or oxidation of glucose in the presence of oxygen to release energy in the form of ATP. Q2 What is anaerobic respiration? Anaerobic respiration is a type of cellular respiration…
Energy is the driving force of any work. Every cellular activity depends on energy, and food is the source of energy. In cells, cellular respiration is the pathway of yielding energy in the form of adenosine triphosphate (ATP). Both eukaryotic…
Q1 What is respiration? The process of breakdown of glucose to release energy, which can be utilized by our body to perform daily chores like walking, sitting or even thinking, is known as respiration. Q2 What is metabolism? Metabolism refers…
Respiration is one of the essential processes carried out by all living organisms to survive. When you run to catch your school bus, you find yourself to be breathing faster. It is because your body requires extra energy for running,…
Q1 1. What is oxygen cycle? The oxygen cycle is a biogeochemical cycle involved in the circulation of the oxygen atoms present in the earth through a series of intricate processes. Q2 2. What is a biogeochemical cycle? A biogeochemical cycle is the…
As we all know, the air is a mixture of gases. The air in the atmosphere is composed of different gases, namely nitrogen (78%), oxygen (21%), argon and other trace gases (1%). According to the earth’s history, oxygen gas was first introduced by cyanobacteria…
Transportation is an essential, natural and the physiological process which occurs in all the higher organisms including plants, animals, and humans. In order to sustain life, this process is important as it functions by constantly transporting, different essential materials to and…
Q1 What is passive diffusion? The simplest plasma membrane transport mechanism is called passive diffusion. It is the movement of ions and other molecules within the cells along the concentration gradient, without any external energy. Q2 What are the three…
