Question

Lila observed that a pond with clear water was covered up with green algae within a week. By which method of reproduction did the algae spread so rapidly?

• A. Budding
• B. Sexual reproduction
• C. Fragmentation
• D. Pollination

Answer 1

The correct option is C

Fragmentation

The correct option is C

Explanation of the correct option:

1. An alga fragments into two or more pieces.
2. These shards or pieces develop into new people.
3. When an organism physically splits from itself, it is called fragmentation.
4. Individual components of the organism mature into independent creatures.
5. When an organism is fragmented, each fragment develops into its own organism.
6. Each component gives birth to a new person. Only a few species are capable of fragmenting and producing new individuals.
7. Sexual reproduction is a type of reproduction in which a haploid female gamete (egg cell) and a haploid male gamete fuse (sperm cell).

Explanation of the incorrect option:

Option A:

Budding is when a new individual emerges from the generative anatomical location of the parent organism.

Option B:

In sexual reproduction, it is impossible for fast multiplication.

Option D:

Pollination is the process of transporting pollen grains from a flower's male anther to its female stigma.

Final answer: The algae spread so rapidly by the method of Fragmentation.
