Reproduction is an important process for propagation of living organism. To facilitate reproduction the genetic material in the cell of the organism needs to be multiplied so that the genetic characters can be passed off into the offspring. The genetic material of most organisms is usually DNA while RNA acts as a messenger. Structure The […]

The whole life cycle of a frog occurs in three stages: Egg Tadpole (larva) Adult frog The development of tadpole (juvenile state) into an adult frog is called metamorphosis. By this a of young larva of frog changes into an adult. To lay eggs, the female frog should mate in the breeding season to ensure […]

The leaves of the trees are colored in different shades of green. This color is imparted due to the presence of various pigments present in the cells of the leaves. The 3 types of pigments present in plants are chlorophyll, carotenoids, and anthocyanins. Chlorophyll imparts the green color to plants. Plastids are membrane-bound cytoplasmic organelles […]

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 […]
