Function of Micronucleus in Paramecium:

The micronucleus in Paramecium has several functions. It is responsible for participating in sexual reproduction and regulating growth. Additionally, it plays a role in genetic exchange during conjugation, a process where two Paramecium individuals exchange genetic material [[1]].

Infectious Disease Caused by:

The infectious disease caused by the following organisms are: a) Euglena viridis - Euglena viridis is a green euglenoid and does not cause an infectious disease [[2]]. b) Paramecium caudatum - Paramecium caudatum is a species of Paramecium and does not cause an infectious disease [[3]]. c) Entamoeba histolytica - Entamoeba histolytica is the causative agent of amoebic dysentery, an infectious disease that affects the intestines [[4]]. d) Volvox - Volvox is a type of green algae and does not cause an infectious disease [[5]].

Differences Between Amoeba and Euglena viridis:

Amoeba and Euglena viridis can be distinguished by the following characteristics: a) Amoeba has an irregular shape and constantly changing form, while Euglena viridis has a more defined shape and is typically elongated [[6]]. b) Amoeba possesses a nucleus within its cell, while Euglena viridis also has a nucleus but it is located within a specialized structure called the "nucleus" [[7]]. c) Amoeba contains contractile vacuoles that help in osmoregulation, while Euglena viridis lacks contractile vacuoles [[8]]. d) Amoeba moves by extending and retracting pseudopods (false feet), while Euglena viridis moves using a whip-like structure called a flagellum [[9]].

Mode of Locomotion in Amoeba:

Amoeba moves by extending and retracting pseudopods or false feet. It extends a pseudopod in the direction it wants to move and then pulls the rest of its body towards it. This process is known as amoeboid movement [[10]].

Reproduction in Amoeba:

Amoeba reproduces through a process called binary fission, which is a form of asexual reproduction. In binary fission, the amoeba divides into two daughter cells, each with a copy of the parent's genetic material. This process allows amoeba to reproduce rapidly under favorable conditions [[11]].

Presence of Two Contractile Vacuoles in a Cell:

The presence of two contractile vacuoles in a cell is a characteristic of Paramecium caudatum, a species of Paramecium. Paramecium caudatum has two contractile vacuoles that help in regulating water balance and excreting excess water from the cell [[12]].

Free-Living Protozoan:

A free-living protozoan refers to a protozoan organism that lives independently and is not parasitic. Among the options provided, the common amoeba (Amoeba proteus) is a free-living protozoan. It is commonly found in freshwater environments and feeds on bacteria and other small organisms [[13]].

Organism Causing Malaria:

The organism that causes malaria is the malarial parasite Plasmodium. There are several species of Plasmodium that can cause malaria in humans, including Plasmodium falciparum, Plasmodium vivax, Plasmodium malariae, and Plasmodium ovale [[14]].
