Answer Details
The irreversible life process by which new protoplasm is added to increase the size and weight of an organism is known as growth.
During growth, an organism's cells divide and differentiate, which allows the organism to increase in size and complexity. This process is usually accompanied by an increase in weight, as the organism accumulates new biomass.
Anabolism and catabolism are two processes involved in metabolism, which refers to the chemical processes that occur within an organism to maintain life. Anabolism is the process of building up complex molecules from simpler ones, while catabolism is the process of breaking down complex molecules into simpler ones to release energy.
Development refers to the process of a single-celled zygote becoming a fully-formed organism, including both growth and differentiation. Therefore, growth is a part of development, but the two terms are not interchangeable.
