In Spirogyra, asexual reproduction takes place bya)division of cell into two cellsb)breaking up of filaments into smaller bitsc)division of cell into many cellsd)formation of young cells from older cellsCorrect answer is option 'B'. Can you explain this answer?

Question

Answer

Breaking of filaments is type of asexual reproduction which is called as fragmentation in this reproduction organism breaks into fragments or filaments upon maturation and spirogyra uses fragmentation as the method of reproduction

Answer

Spirogyra species can reproduce both sexually and asexually. Asexual, or vegetative, reproduction occurs by simple fragmentation of the filaments. Sexual reproduction occurs by a process known as conjugation, in which cells of two filaments lying side by side are joined by outgrowths called conjugation tubes.

Answer

----))) Spirogyra is a genus of filamentous green algae. It reproduces by fragmentation. The body of spirogyra on maturing simply breaks up into smaller pieces or fragments due to water current, these pieces or fragments grow into new individuals.

•Thus, the correct answer is option B.

Answer

In spirogyra,it simply breaks up into smaller pieces upon maturation.These pieces or fragments grow into new individuals. This type of asexual reproduction are known as FRAGMENTATION.

Answer

Introduction:
Spirogyra is a genus of filamentous green algae that belongs to the division Chlorophyta. It is commonly found in freshwater habitats such as ponds, lakes, and slow-moving streams. Spirogyra reproduces both sexually and asexually. In asexual reproduction, the organism can reproduce by various methods, one of which is the breaking up of filaments into smaller bits.

Explanation:
Asexual reproduction in Spirogyra occurs through fragmentation, which involves the breaking up of filaments into smaller bits. This process can be further explained as follows:

1. Filamentous Structure:
Spirogyra consists of long, thread-like filaments that are made up of cylindrical cells. These filaments are often found floating on the surface of water bodies.

2. Fragmentation:
During asexual reproduction, the filamentous structure of Spirogyra undergoes fragmentation. This means that the filaments break up into smaller pieces or fragments.

3. Formation of New Filaments:
Each fragment of Spirogyra has the potential to grow into a new filament. These fragments can float freely in the water until they find suitable conditions for growth.

4. Regeneration:
The fragments of Spirogyra undergo regeneration, where each fragment develops into a new filament by cell division. The cells in the fragments divide repeatedly to form a series of cylindrical cells, which eventually elongate and differentiate into a new filament.

5. Importance of Fragmentation:
Fragmentation in Spirogyra is an efficient method of asexual reproduction. It allows the organism to rapidly colonize new habitats and expand its population. Additionally, fragmentation ensures that the genetic material is distributed equally among the new filaments, maintaining genetic diversity within the species.

Conclusion:
In Spirogyra, asexual reproduction occurs through the breaking up of filaments into smaller bits, a process known as fragmentation. This allows the organism to produce new filaments, rapidly colonize new habitats, and maintain genetic diversity within the species.
