Answer 1

Botany, also called plant science(s), plant biology or phytology, is the science ofplant life and a branch of biology. Abotanist, plant scientist or phytologist is a scientist who specialises in this field. The term "botany" comes from the Ancient Greek word βοτάνη (botanē) meaning "pasture", "grass", or "fodder"; βοτάνη is in turn derived from βόσκειν (boskein), "to feed" or "to graze".Traditionally, botany has also included the study of fungiand algae by mycologists and phycologistsrespectively, with the study of these three groups of organisms remaining within the sphere of interest of the International Botanical Congress. Nowadays, botanists (in the strict sense) study approximately 410,000 species of land plants of which some 391,000 species are vascular plants(including ca 369,000 species of flowering plants),and ca 20,000 are bryophytes
