A.Nephridia
B.Henle's loop
C.Nephron
D.Pyramid

Answer 1

Hint: The chemical reactions taking place in the body are responsible for producing different types of waste items like carbon dioxide, water, salts, urea and uric acid. The accumulation of waste products beyond a level inside our body which becomes harmful to the body. The excretory organs are responsible for removing these wastes. The process of removing metabolic wastes from the body is known as excretion.

Complete answer:
A nephron may be a unit of structure and work in a kidney. Each kidney contains about a million nephrons. A nephron is the fundamental basic and utilitarian unit of the kidney. The title nephron comes from the Greek word (nephros) meaning kidney. Its chief work is to direct water and dissolvable substances by sifting the blood, reabsorbing what is required and excreting the rest as pee. A nephron may be a long tubule differentiated into Bowman's capsule, PCT, the circle of Henle and DCT, each portion possessing a specific function. So, the proper reply is (C).

There are no particular excretory structures present in plants just like the animals as: Maximum of plant wastes are vaporous in nature and are misplaced by the method of diffusion through the stomata. Oxygen is discharged amid the method of photosynthesis and carbon dioxide is used.

Note: The nephrons are two types: The cortical nephrons, having their glomeruli present in the outer cortex. They are known to have a shorter loop of Henle, that extends up to the outer medulla. The juxtamedullary nephrons have their glomeruli present near the corticomedullary border and a longer loop of Henle.
