Question

Which of the following groups consist of organisms that multiply by fragmentation?
A. Earthworm, Amoeba, fungi
B. Earthworm, fungi, bacteria
C. Fungi, filamentous algae, protonema of mosses
D. Amoeba, Hydra, Bacteria

Answer 1

Hint: One of the most significant processes that mostly happen in a multicellular organism is the fragmentation process. Fragmentation is a type of asexual reproduction in multicellular organisms in which an organism is divided into fragments. Each of these fragments grows into adult species, fully grown individuals that are similar to their parents genetically and morphologically.

Complete answer:
The key feature of the fragmentation process is that this process can occur deliberately as well as accidentally. Man-made causes or environmental changes, for example, can cause the organism to split and eventually grow into complete and mature parent-like organisms.
Vegetative reproduction occurs in fungi by fragmentation or budding (in yeast). A sexual reproduction occurs in algae by means of different types of spores. Vegetative reproduction occurs by fragmentation, development of secondary protonema, gemmae, tubers, etc. in Bryopsida (mosses),
For asexual reproduction, the fragmentation process is very vital in biology. This is the form of reproduction in which the parent individual's small organs or parts of the body get separated and eventually develop into a fully mature organism.

Hence, the correct answer is option (C).

Note: In reproduction, the words fragmentation and regeneration are sometimes referred to as the words used. Even, there are some common distinctions that are very noticeable in them. The fragmentation process also happens when a portion of an organism is divided into smaller fragments that can expand into similar organisms to distinguish them. Regeneration, on the other hand, is one in which the organism is able to regrow those missing body parts.
