Difference between prokaryotic and eukaryotic cell

What do you mean by Prokaryotic Cells? Prokaryotic cells have a single membrane or one envelope system where there exist no definite cell organelles. The protoplasm is not differentiated to the nucleoplasm and cytoplasm and the genetic material occurs without any nuclear membrane. The naked genetic material is called a nucleoid. The bacteria and blue-green

Concept of an Electric Charge

Electric Charge: The matter on the earth which occupies the space may be solid, liquid or gaseous. The matter is made up of one or more elements. Each element is made up of many atoms which are of similar nature. Now a days, scientists are successful in breaking atoms and studying the result products. According

Acid Rain: Effects & Control Measures

What is Acid Rain? Those gases which combine with water to form acids are called acidic gases. Examples of acidic gases are sulfur dioxide ( SO₂) and nitrogen dioxide (NO2). The sulfur dioxide gas present in polluted air forms sulfuric acid (H2SO4) whereas nitrogen dioxide gas present in polluted air forms nitric acid (HNO₃). When the

Carbon Cycle In Nature

Carbon Cycle: The carbon element is often considered as the basis of all life. Carbon is a basic constituent of living organisms. In fact, carbon is the most essential constituent of all the major organic compounds of the protoplasm (living substance) like carbohydrates, fats, proteins, and nucleic acids. In other words, the carbon element exists

Biogeochemical Cycle

What is Biogeochemical Cycle? The biogeochemical cycle may be defined as the more or less circular path which brings about the circulation of chemicals and elements, including all essential elements from the environment to the organisms and back to the environment. Types of Biogeochemical Cycle: Gaseous Cycles: In which the reservoir is in the atmosphere.

Nitrogen Cycle In Nature

Nitrogen Cycle: The cyclic process by which nitrogen element is circulated continuously through the living and non-living components of the biosphere (like atmosphere, soil, water, plants, and animals) is called the nitrogen cycle in nature. In simple words, the circulation of nitrogen in nature is called the nitrogen cycle. Nitrogen gas of the atmosphere is

Oxygen Cycle In Nature

Oxygen Cycle: Oxygen is the second most abundant element in the earth’s atmosphere. Oxygen forms about 20.9 percent of the atmospheric gases. Oxygen is an essential element for the building up of living organisms and their life processes such as respiration. Oxygen exists in free molecular form as oxygen gas O2. Oxygen is present in
