Biology Questions On Excretion 1

Biology Questions On Excretion 1; Excretion refers to the biological process that involves the removal of metabolic waste products, excess substances, and toxins from the body of an organism. This is a critical process for maintaining homeostasis and preventing the accumulation of harmful substances within the body. In this biology class note, we will examine various aspects of excretion, including the different types of excretory structures, the mechanisms involved in excretion, and the excretory products produced by plants.
