Botany
Botany is the branch of biology that deals with the study of plants, including their structure, physiology, reproduction, and biochemical processes.
Botany is a very vast and comprehensive science and is divided into various major branches such as morphology, histology, physiology, plant anatomy, genetics, cytology, taxonomy, ecology, paleobotany, plant geography, etc.
The scope of botany and its consequent importance is vast and immense. For the very existence of not only human beings but also all animals, plants are necessary.
The study of botany forms a necessary informational background for students preparing for careers in agriculture, horticulture, forestry, bacteriology, pharmacology, soil conservation, and other related fields.

Economic Importance of Fungi
Fungi lack the chlorophyll pigment essential for independent existence. Hence, they must get their food from other living organisms or from dead or decaying organic matter. Economical fungi have great…
Pteridospermales (Cycadofilicales): An Overview
The Pteridospermales or Cycadofilicales are characteristic gymnospermous plants that bore fern-like foliage, which in turn bore seeds that were unprotected. Hence, they are known as seed ferns. Pteridospermales is a…

The Bennettitales (Cycadeoidales) are a fossil group found from the Triassic to the lower Cretaceous, but were predominant in the Jurassic period of the Mesozoic era in South America, North…
Degeneration of Sexuality in Fungi
Sexuality in fungi is diverse and fascinating. In fungi, gradual degeneration of sexuality can be observed. Degeneration of sexuality means functional and structural degeneration of sex organs, leading to the…
