Sample NECO SSCE Biology 2007 questions

1. In a flowering plant, one male gamete fuses with the egg cell; what does the second male gamete normally fuse with?
  1. The integuments of the ovule
  2. The stigma cells
  3. The polar nuclei in the embryo sac
  4. The synergid cell wall

Answer: C. The polar nuclei in the embryo sac

The second male gamete fuses with the polar nuclei to form the endosperm-producing primary endosperm nucleus.

2. A farmer plants pieces of yam tuber, each containing an active eye; which structure in the eye enables a new shoot to develop?
  1. A dormant bud
  2. A root hair
  3. A lenticel
  4. A pollen grain

Answer: A. A dormant bud

Each yam eye contains a bud that can grow into a new shoot.

3. A bird eats a brightly coloured fleshy fruit and later deposits its undamaged seeds in a different area; which dispersal method is illustrated?
  1. Wind dispersal
  2. Water dispersal
  3. Explosive dispersal
  4. Dispersal by animals

Answer: D. Dispersal by animals

Animals can carry seeds away from the parent plant after eating fruits and later excreting the seeds.

4. During epigeal germination, the cotyledons are lifted above the soil surface mainly because which part elongates?
  1. The radicle
  2. The hypocotyl
  3. The plumule
  4. The testa

Answer: B. The hypocotyl

Elongation of the hypocotyl lifts the cotyledons above the soil in epigeal germination.

5. Which region is chiefly responsible for the increase in length of a young root?
  1. The apical meristem near the root tip
  2. The cork layer behind the root tip
  3. The root-hair zone only
  4. The mature xylem at the root base

Answer: A. The apical meristem near the root tip

Cells in the root apical meristem divide and then elongate, producing primary growth in length.
