Question

Which of the following pair is not correctly matched?

• A. Binary fission - Sargassum
• B. Conidia - Penicillium
• C. Offset - Water hyacinth
• D. Rhizome - Banana

Answer 1

The correct option is A Binary fission - Sargassum

Binary fission is a process of asexual reproduction in which a cell divides into two equal halves and forms two independent daughter cells. Amoeba and Paramecium are organisms that exhibit binary fission. Sargassum, on the other hand, is a free-floating algae that undergoes vegetative and sexual reproduction. Vegetative reproduction takes place through frag­mentation, and oogamy is the mode of sexual reproduction.
Penicillium undergoes asexual reproduction with the help of unique reproductory structures called conidia that have a characteristic thick-wall and non-motile spores. Water hyacinths propagate vegetatively with the help of offsets (vegetative propagules), which is a subaerial stem. They develop crowns at their ends, and each horizontal branch grows into an independent plant. A rhizome is an underground stem used for vegetative propagation and can give rise to new offspring. They are found in ginger and banana.
