What is Botany and Why are Plants Important?

What is Botany?
Botany, also called plant science or plant biology, is the science of plant life and a branch of biology. A botanist is a scientist who specializes in this field of study. The term “botany” comes from the Ancient Greek word βοτάνη (botane) meaning “pasture”, “grass”, or “fodder”; βοτάνη is in turn derived from βόσκειν (boskein), “to feed” or “to graze”. A person who studies plants may be called a botanist or a plant scientist.

What are Plants?
Plants are living multicellular organisms of the kingdom Plantae. Plants are eukaryotes that have cell walls made of cellulose. They develop from multicellular embryos and carry out photosynthesis using the green pigments chlorophyll a and b.

Why are plants important?
Without plants, complex animal life (including humans) could not survive.
All living things are dependent either directly or indirectly on the energy produced by photosynthesis & the byproduct of this process – oxygen.
Plants also reduce the amount of carbon dioxide present in the atmosphere, reduce erosion, and influence water levels and quality.
