Plants require specific conditions for their growth, which include water, oxygen, It is defined as all the changes that an organism goes through during its life cycle, right from seed germination to senescence. During the growth periods there are several parameters which are involved, such as increase in weight, area, length, volume, and number of the plant part. Plants respond in different ways to environment and phases of life and give rise to different forms of structures. 2. Phosphorous is used by plants largely for root growth and development.
