Here we will see bacteria vs virus differences in terms of structure, habits, parasitic nature and other features. Bacteria vs Virus Sl.No Character Bacteria Virus 1 Live Organism Yes they are Living Intermediate between living and nonliving. Inside host live 2 Cell Single-celled organism A-cellular (no cell) just a particle 3 Size Bigger in size, […]

The cells of plants are broadly divided into two types. The permanent tissues generally don’t divide further. The types of plant cells are Parenchyma Collenchyma, and Sclerenchyma. However, these cells are arranged into tissues as Simple tissues Complex tissues Simple tissues Simple tissues making up the ground layers in plants. They are of three types […]

Algae are simple, photosynthetic, non-flowering, aquatic eukaryotic organisms that do not develop reproductive organs. There are different types of algae like Euglenophyta Chrysophyta Pyrophyta Chlorophyta Rhodophyta Phaeophyta Xanthophyta Algae can be unicellular or multicellular organisms. Algae habitats in both fresh and marine waters, in the form of free-floating or attached to the substratum. The multicellular […]

DNA and RNA are both nucleic acids which are present in almost all the living cells. There are few differences between the RNA and DNA due to which their role and function in the body varies considerably. Difference between RNA and DNA Sl.No Characteristics RNA DNA 1 Shape RNA is present as a singlestrand in […]

A citrate utilization test is one of the IMVic series groups of tests for identification of bacteria. IMViC stands for Indole, Methyl red, VP, and citrate test. A citrate utilization test helps to detect the organism’s ability to produce citrase enzymes. Those organisms which have an ability to use citrate as the sole source of […]

It is called the VP test, it is one of the tests for the identification of bacteria. In 1898, Voges and Proskauer, a German bacteriologist, first observed the production of red color in the cultures grown in specific media after the addition of potassium hydroxide. But later Harden revealed that red color was due to […]

Cell signaling is a method of communication of one cell with other cells. This is done by following methods like Contact dependent cell signaling Paracrine signaling Autocrine signaling Endocrine signaling Synaptic signaling. Cells need to contact with other cells for normal physiology of the body. Sometimes they signal the nearby cells, and other times they […]

The alcoholic functional group is the –OH or hydroxyl group attached to a carbon atom. Alcohol contains one or more hydroxyl groups directly attached to the carbon atom of an aliphatic chain. When the hydroxyl is attached to a carbon atom in an aromatic system, it is known as phenol. Alcohols are acidic in nature […]

Leaves are the essential organs of a plant. They are dorsoventrally flattened, green-colored parts of a vascular plant. It is a lateral appendage of the stem. A leaf arises from the shoot apical meristem in the young plant. In older plants, leaves develop at the node of the stem and bear a bud in its […]

Before we talk about Reproduction in Plants, it is important to understand its purpose. Every living organism has a fixed lifespan and dies one day. For the maintenance of the population of a particular organism, new organisms of that species must be produced. Thus reproduction is the process of production of new individuals from their […]
