Answer 1

The correct matches are as follows:

(1) tracheae - (b) insects

(2) lenticels - (d) stem

(3) skin - (f) earthworm

(4) gills - (e) fish

(5) lungs - (c) birds

(6) stomata - (a) leaves

The matches represent the respiratory organs of different organisms.

• Tracheae are air-filled tubes that act as respiratory organs in insects.
• Lenticels are numerous tiny openings present on the stems of woody plants that are responsible for gaseous exchange.
• There is no particular respiratory organ in earthworms. They respire through moist skin.
• In fishes, the gills help in breathing by taking out dissolved oxygen from water.
• In birds, the pair of lungs help in the exchange of gases between the organism's body and surroundings.
• Leaves have many small pores on their surface called stomata that are responsible for gaseous exchange.
