Here are 10 one-word answer type questions from the topic Fragmentation with answers and explanations (explanation is given immediately after each question and answer as requested):
1)
Question: What is the method of asexual reproduction seen in algae like Spirogyra?
Answer: Fragmentation
Explanation: Fragmentation is a method of asexual reproduction in which an organism breaks up into two or more fragments and each fragment grows into a new individual .
2)
Question: Which plant group shows reproduction by fragmentation?
Answer: Algae
Explanation: Algae, especially Spirogyra, reproduce rapidly by fragmentation when sufficient water and nutrients are available .
3)
Question: What is the name of the slimy green patches seen in ponds?
Answer: Algae
Explanation: The green patches seen in stagnant water bodies are due to the presence of algae which multiply by fragmentation .
4)
Question: Which water body is most suitable to observe fragmentation in algae?
Answer: Pond
Explanation: Algae grow rapidly in ponds and stagnant water bodies, where they reproduce by fragmentation .
5)
Question: What is the initial structure that breaks to form new plants in fragmentation?
Answer: Filament
Explanation: In Spirogyra, the long filament breaks into smaller fragments which develop into new individuals .
6)
Question: What is required, along with water, for rapid multiplication of algae?
Answer: Nutrients
Explanation: Availability of nutrients along with water helps algae to grow and reproduce quickly by fragmentation .
7)
Question: What is the name of the process in which each broken part of an alga forms a new individual?
Answer: Fragmentation
Explanation: The process in which each broken part of an alga develops into a new individual is called fragmentation .
8)
Question: In which season is fragmentation in algae more commonly observed?
Answer: Rainy
Explanation: During the rainy season, stagnant water bodies provide favourable conditions for algae to multiply rapidly by fragmentation .
9)
Question: What type of reproduction is fragmentation—sexual or asexual?
Answer: Asexual
Explanation: Fragmentation is a type of asexual reproduction because it involves only one parent and no gamete formation .
10)
Question: Which green aquatic organism reproduces by fragmentation?
Answer: Spirogyra
Explanation: Spirogyra is a filamentous green alga that reproduces by breaking into fragments, each of which grows into a new organism .
