Ques. 1AIPMT 2012 (Prelims)
Which one of the following is correctly matched?
- Onion – Bulb
- Ginger – Sucker
- Chlamydomonas – Conidia
- Yeast – Zoospores
Answer
(1) Onion – Bulb
Solution
As per NCERT, ginger reproduces vegetatively by rhizome, not sucker, so (2) is wrong.
Chlamydomonas reproduces asexually by zoospores, while conidia are formed by Penicillium, so (3) is wrong.
Yeast reproduces asexually by budding (and ascospores), not zoospores, so (4) is wrong.
Onion stores food in fleshy leaves around a reduced stem, i.e., a bulb, which also serves for vegetative propagation.
∴ Onion – Bulb is correctly matched.
Answer: (1)
