HOTS | Pollution & Plastics | Why should we not throw plastic bottles into the river?

Water pollution (or aquatic pollution) is the contamination of water bodies, usually as a result of human activities, so that it negatively affects its uses. Water bodies include lakes, rivers, oceans, aquifers, reservoirs and groundwater. Water pollution results when contaminants are introduced into these water bodies. Water pollution can be attributed to one of four sources: sewage discharges, industrial activities, agricultural activities, and urban runoff…

What is Osmosis? |Potato Experiment

Naman Biology, Osmosis

Osmosis is a vital process in biological systems, as biological membranes are semipermeable. In general, these membranes are impermeable to large and polar molecules, such as ions, proteins, and polysaccharides, while being permeable to non-polar or hydrophobic molecules like lipids as well as to small molecules like oxygen, carbon dioxide,…

Microorganism Part-2

Naman Biology, Microorganism

A microorganism, or microbe, is an organism of microscopic size, which may exist in its single-celled form or as a colony of cells. The possible existence of unseen microbial life was suspected from ancient times, such as in Jain scriptures from sixth century BC India. Because microorganisms include most unicellular organisms from…

Microorganism

Naman Biology, Microorganism

A microorganism is a living thing that is too small to be seen with the naked eye. Examples of microorganisms include bacteria, archaea, algae, protozoa, and microscopic animals such as the dust mite. Microorganisms are found virtually everywhere, except for environments that have been made artificially sterile by humans. Even…

Reproduction in Plants

Naman Biology, Plants

Plants reproduction is the production of new offspring in plants, which can be accomplished by sexual or asexual reproduction. Sexual reproduction produces offspring by the fusion of gametes, resulting in offspring genetically different from either parent. Asexual reproduction produces new individuals without the fusion of gametes. The resulting clonal plants…

What controls our inherited traits?

Naman Biology, DNA & Genetics

Heredity is a process in which organisms acquire characteristics from their parents. These characteristics are called traits. Every individual is unique because they have a unique set of traits. The traits which are transmitted by the parent to its offspring during the process of fertilization are inherited traits. This inheritance…

Transportation of Water in Plants – Xylem

Naman Biology, Plants

Xylem is one of the two types of transport tissue in vascular plants, the other being phloem. The basic function of xylem is to transport water from roots to stems and leaves, but it also transports nutrients. The xylem, vessels and tracheids of the roots, stems and leaves are interconnected…

Soil Erosion – How it can be prevented

Naman Soil, Soil, Biology, Environmental Studies

In earth science, erosion is the action of surface processes (such as water flow or wind) that removes soil, rock, or dissolved material from one location on the Earth’s crust, and then transports it to another location where it is deposited. Erosion is distinct from weathering which involves no movement.…

Observing Stomata on a peel of Leaf

Naman Biology, Plants

In botany, a stoma/stomata is a pore found in the epidermis of leaves, stems, and other organs, that controls the rate of gas exchange. The pore is bordered by a pair of specialized parenchyma cells known as guard cells that are responsible for regulating the size of the stomatal opening.…
