In 1959, R H Whittaker, classified living organisms into five categories that are Monera, Protista, Fungi, Plantae and Animalia. In particular, Kingdom Plantae, is further classified into 5 divisions which are Thallophyta, Bryophyta, Pteridophyta, Gymnosperms and Angiosperms. Thallophyta Thallophytes are the simplest plants under kingdom plantae. Thallophytes do not contain different parts like stem, leaves, […]

Soil
Soil is an important natural resource as it provides growth of plants, provides food and shelter and many more. If soil is in rock form, it becomes difficult to use it for different purposes. A natural process of weathering takes place to convert rocks into fine particles called soil. Process of Soil Formation Sun Due […]

Phylum vertebrata is divided into five classes Pisces, Amphibia, Reptilia, Aves and Mammalia. Pisces Class pisces contains all fishes. Pisces are aquatic animals having streamlined body and muscular tail. Skin is covered with scales and heart of pisces are […]
Ohm’s Law – Relation between Resistance, Potential Difference and Current
Ohm’s law determines the relation between the potential difference and the flow of current. Therefore, Ohm’s law states that, “ At constant temperature potential difference(V) is directly proportional to current (I)” V∝ I Verification of Ohm’s Law At constant temperature, if we plot a graph of current versus potential difference, a straight line graph passing […]
What is Motion?
A body is said to be in motion, if it changes its position with respect to time. If not so, then body is said to be at rest. A racing car, flying aeroplane, flowing rivers, rolling ball are all in motion whereas, a standing bicycle, a tree, wall of room are at rest. To understand […]
Sex Determination in Human Beings
Introduction to Sex Determination Sex determination takes place with the help of genes inherited from parents. Particularly, genes are present on chromosomes in the nucleus of cell. Male and female gamete contains chromosomes. Fertilisation of these gametes, leads to the formation of zygote. The developement of zygote further gives rise to new individual. “The biological […]

Animal tissues and its functions
Animal tissue is classified into four types that are epithelial tissue, muscular tissue, connective tissue and nervous tissue. Epithelial tissue Cells in epithelial tissues are arranged in tiles format i.e. are tightly pack such that there are no intercellular spaces in it. Epithelial tissues are present in skin, respiratory tract, in lungs alveoli, in kidney […]
