	Column I		Column II
A	Peritrichous flagellation	1	Ginkgo
B	Living fossil	2	Macrocystis
C	Rhizophore	3	Escherichia coli
D	Smallest flowering plant	4	Selaginella
E	Largest perennial alga	5	Wolffia

• A. A-3, B-1, C-4, D-5, E-2
• B. A-1, B-2, C-3, D-4, E-5
• C. A-2, B-3, C-4, D-5, E-1
• D. A-3, B-4, C-5, D-2, E-1

Answer 1

The correct option is A A-3, B-1, C-4, D-5, E-2

Peritrichous flagellation means having flagella projecting in all directions (e.g., E. coli).

Gingko, is a living fossil. Newly found specimens that grew more than a hundred million years ago are remarkably similar to present-day plants.

Selaginella has a rhizophore which is a proplike structure that originates at a point of branching and that forks dichotomously after making contact with the soil or a hard surface.

The flower of Wolffia is the smallest known flower in the world, measuring merely 0.3 mm long. It has one stamen and one pistil.

Macrocystis, a kelp (see weed) is the largest of all algae. The stage of the life cycle that is usually seen is the sporophyte, which is perennial and individuals persist for many years. Therefore correct combination is A-3, B-1, C-4, D-5, E-2. Hence option A is correct.
