Evolution of Sporophyte in Bryophytes
The evolution of sporophyte in Bryophytes have been explained with the help of two theories: one is the Antithetic Theory or Theory of Sterilization and the other one is the…
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.
