They occur naturally in the plant parts and are also chemically synthesized. The principal naturally occurring auxin is Indole-3-Acetic Acid (IAA) and Indole-3-Butyric Acid (IBA) is a synthetic auxin. Continue reading How do Auxins affect Plant growth?

The Kingdom Protista includes diverse kinds of predominantly water-dwelling unicellular eukaryotic microorganism. Protists, like Monerans, have an immense reproductive potential. In an optimal environment, they may reproduce several times a day. This is mainly by asexual reproduction, using the process of mitosis. However, they also reproduce sexually. Continue reading Sexual Reproduction – An Important Innovation of the Early Protists.
Why are some fungi grouped under “fungi imperfecti”?
There are over 100,000 species of fungi. Some of them are one-celled like the yeasts; others are complex like mushrooms and some of them are called imperfect fungi. Fungi are the major decomposers (besides bacteria) and some parasitic forms of fungi may also cause diseases in plants and animals.
