Questions and Answers

What is the primary purpose of reproduction in living organisms?

To create clones
To produce genetically identical offspring
To produce sex cells
To maintain the continuity of life (correct)

What is the characteristic of asexual reproduction?

Occurs in multicellular organisms only
Produces genetically identical offspring (correct)
Involves the fusion of gametes
Involves the production of seeds

What is the process by which Spirogyra reproduces asexually?

Vegetative propagation

What is the main difference between asexual and sexual reproduction?

In asexual reproduction, a single organism produces genetically identical offspring, whereas in sexual reproduction, fusion of two compatible gametes or sex cells occurs, resulting in genetically diverse offspring. Signup and view all the answers

What is the significance of asexual reproduction in unicellular organisms like Protosiphon and yeast?

Asexual reproduction ensures the rapid production of new individuals, allowing the population to quickly adapt to favourable conditions and occupy available resources. Signup and view all the answers

How does fragmentation contribute to asexual reproduction in multicellular organisms?

Fragmentation enables multicellular organisms to break into fragments, which can grow into new individuals, thereby perpetuating the species. Signup and view all the answers

What is the role of zoospores in the asexual reproduction of Chlamydomonas?

Flagellated, motile zoospores produced by Chlamydomonas can grow independently into new individuals, allowing the species to reproduce asexually. Signup and view all the answers

What is the primary advantage of asexual reproduction in terms of species continuity?

Asexual reproduction ensures the continuation of a species by producing genetically identical offspring, thereby maintaining the species' characteristics and traits. Signup and view all the answers

How does vegetative propagation occur in nature, and what is its significance?

Vegetative propagation occurs through the growth of new plants from vegetative parts, such as roots, stems, or leaves, and is significant as it allows plants to reproduce without seeds. Signup and view all the answers
