Question

Identify the plants with the following characters respectively:
I) Swollen storage fibrous roots
II) Roots absorbing moisture from atmosphere
III) Roots to get oxygen for respiration
A) turnip, B) Avicennia, C) Vanda, D) carrot, E) Asparagus, F) Maize, G) sweet potato

• A. A, C, D
• B. B, F, G
• C. E, C, B
• D. F, C, A

Hint:

Pneumatophores are always found in swampy mangroves like Avicennia and Rhizophora.
Recognizing respiratory roots immediately associates the third character with Avicennia (B).

Answer 1

The Correct Option is C

Step 1: Separate the three root jobs mentioned.
One root type stores food and swells up, one type pulls moisture straight from humid air, and one type pokes up to grab oxygen for the plant sitting in waterlogged or saline soil.
Step 2: Match plants to jobs one at a time.
Asparagus (E) develops clustered tuberous roots built purely for storage, so it fits the storage role. Vanda (C) is an epiphytic orchid whose hanging aerial roots are wrapped in a spongy velamen tissue that soaks up atmospheric moisture, so it fits the second role. Avicennia (B), a mangrove tree, sends up pneumatophores through the mud to breathe, so it fits the oxygen absorbing role.
Step 3: Rule out the distractor plants.
Turnip and carrot are simple storage taproots not fibrous ones, Maize has fibrous adventitious roots with no special breathing or moisture role, and sweet potato is a storage root too but not fibrous, so none of these replace E, C, B.
Final answer: Option 3, E, C, B correctly lines up storage, moisture absorbing and oxygen absorbing roots with Asparagus, Vanda and Avicennia.
