Plant physiology is that branch of plant sciences that aims to understand how plants live and function. Its objective is to explain all life processes of plants by a minimal number of comprehensive principles founded in chemistry, physics, and mathematics. Plant physiology studies the ways in which plants absorb minerals and water, grow and develop, flower and bear fruit. It also deals with photosynthesis, respiration, biosynthesis and the accumulation of substances and translocation, which together enable plants to grow and reproduce themselves.
