A-(ii), B-(iii), C-(i). |
The correct answer is Option (2) -A-(ii), B-(iii), C-(i). A survey of animal kingdom presents a variety of excretory structures. In most of the invertebrates, these structures are simple tubular forms whereas vertebrates have complex tubular organs called kidneys. Protonephridia or flame cells are the excretory structures in Platyhelminthes (Flatworms, e.g., Planaria), rotifers, some annelids and the cephalochordate – Amphioxus. Nephridia are the tubular excretory structures of earthworms and other annelids. Malpighian tubules are the excretory structures of most of the insects including cockroaches. Antennal glands or green glands perform the excretory function in crustaceans like prawns. |
