Answer 1

Answer: (A)

Flagellation is the arrangement of flagella over the body surface of a bacterial cell. Peritrichous bacteria has flagella all over the surface of cell e.g. E. coli. Ginkgo belongs to order Ginkgoales of gymnosperms. It is called living fossil because it is the single living genus in a big fossilised order. Rhizophore is a leafless, colourless, positively geotropic elongated structure that grows down from the point of bifurcation of stem. It occurs in Selaginella. Macrocystis belongs to class Phaeophyceae. It is the largest perennial alga, about 40-60 m in size. Wolffia is the smallest flowering plant.
