I. Stomata --> Spirogyra
II. Alveoli --> Earthworm
III. Malpighian tubule -> Mammal
IV. Contractile vacuole -> Protozoa
Which of the above structures is correctly matched with the organisms in which it is found?
The correct answer is C.
Stomata allow a plant to take in carbon dioxide, which is needed for photosynthesis. They also help to reduce water loss.
The alveoli are where the lungs and the blood exchange oxygen and carbon dioxide during the process of breathing in and breathing out.
The Malpighian tubules are tubular structures that are free floating in the haemolymph and function as excretory and osmoregulatory organs of insects.
Contractile vacuoles (in the cells of the lower organisms) protect a cell from absorbing too much water and potentially exploding by excreting excess water.
