Question

The protist that reproduces both by binary fission and conjugation is
(a) Amoeba
(b) Euglena
(c) Paramecium
(d) Monocytosis

Answer 1

Hint:
Protists are mostly unicellular eukaryotic organisms. Most eukaryotes are single-celled organisms. There is variation in body form, nutrition, and reproduction in these organisms. Protists are capable of sexual as well as asexual reproduction.

Complete step by step answer:
Both asexual and sexual reproduction occur among protozoa. Protozoa are animal-like protists. One of the simplest and most common forms of asexual reproduction is binary fission, a mitotic process. In multiple fission, a large number of daughter cells form from the division of a single protozoan.
Paramecium reproduces sexually by conjugation. It is a process in which two individuals exchange their genetic materials mutually. Conjugation interrupts continuous multiplication by binary fission which is crucial for the rejuvenation and survival of individuals. Amoeba chooses an asexual mode of reproduction. It reproduces through binary fission which is a process in which an individual divides itself into two daughter cells. Euglena also reproduces asexually by longitudinal binary fission. The adult mature monocytosis is called a trophozoite. The mode of reproduction in monocytosis is sexual and is always followed by asexual reproduction.

Option ‘C’ is correct

Note:
Asexual reproduction is the simplest form of reproduction that does not involve meiosis, gamete formation, and fertilization (i.e., a fusion of gametes). Instead, it results in the multiplication of genetically identical individuals(clones). Sexual reproduction is a form of reproduction that involves meiosis, gamete formation, and fertilization
