Question

The protozoan parasite which possesses a food vacuole is [EAMCET 1998]
A) Leptomonas
B) Plasmodium
C) Trypanosoma
D) Leishmania

Answer 1

Answer: Plasmodium

Explanation:

The food vacuole in plasmodium is lysosome like organelle, where erythrocyte hemoglobin digestion occurs. It is the favourite target in the development of animalatrians.

Answer 2

Answer:

The protozoan parasite which possesses a food vacuole is B) Plasmodium.

Explanation:

• Plasmodium is a protozoan that is unlikely to have a contractile vacuole. The major function of the contractile vacuole is to maintain the osmotic pressure of an organism's fluid at a constant level, by taking control of the concentration of salt and water content.

• Plasmodium is usually found in freshwater, so the salt concentration inside the cell is higher than outside. Then, it doesn't need osmoregulation, as it is a terrestrial parasite.

• Organisms living in the aquatic environments have a lower convergence of molecules than is tracked down in the inside of their cells — an osmotically hypotonic climate — step by step gain water assuming they equilibrate with their natural surroundings.

• On the off chance that this interaction stays uncontrolled, the cell enlarges and explodes. In protozoans, the support of the osmotic slope between the cell cytoplasm and the climate is accomplished by the contractile vacuole.

• Protozoans have temporary food or stomach related vacuoles. The quantity of these layer bound cell organelles relies upon taking care of propensities for the living being.

• The Plasmodium falciparum food or digestive vacuole (FV) is a lysosome-like organelle where erythrocyte haemoglobin processing happens. It is a most loved focus in the improvement of antimalarials.

Therefore the correct option is B) Plasmodium.
