Match items in Column I with those in Column II -

Pick the matching item from Column II for each row.
Column I
- A. Peritrichous flagellation Match for A
- B. Living fossil Match for B
- C. Rhizophore Match for C
- D. Smallest flowering plant Match for D
- E. Largest perennial alga Match for E
Column II
- J. Ginkgo
- K. Macrocystis
- L. Escherichia coli
- M. Selaginella
- N. Wolffia
Correct answer: A → L, B → J, C → M, D → N, E → K

Peritrichous flagellation means that the flagella are distributed all over the surface of the bacterial cell; Escherichia coli has peritrichous flagella. So A - L.
Ginkgo biloba is called a living fossil because it has survived almost unchanged since the Mesozoic era. So B - J.
Rhizophores are leafless, colourless downward-growing branches that bear roots at their tips; they are found in Selaginella. So C - M.
Wolffia, a tiny floating duckweed of family Lemnaceae, is the smallest flowering plant. So D - N.
Macrocystis, a brown alga (kelp), is the largest perennial alga, reaching lengths of about 60 m. So E - K.
Correct match: A-L, B-J, C-M, D-N, E-K.
