Sample NECO SSCE Biology 2009 questions

1. In a flowering plant, what is the name of the event in which a pollen grain is transferred to a receptive stigma?
  1. Fertilization
  2. Germination
  3. Pollination
  4. Dispersal

Answer: C. Pollination

Pollination is the transfer of pollen grains from an anther to a stigma.

2. Which is an important biological advantage of sexual reproduction?
  1. It produces genetic variation among offspring.
  2. It requires only one parent in every case.
  3. It produces offspring that are always genetically identical.
  4. It prevents mutations from occurring.

Answer: A. It produces genetic variation among offspring.

The mixing of genetic material during sexual reproduction creates variation among offspring.

3. Which feature is most likely to attract insect pollinators to a flower?
  1. Small, dull petals and exposed anthers
  2. Feathery stigma and abundant light pollen
  3. A long, dangling catkin
  4. Brightly coloured petals with nectar

Answer: D. Brightly coloured petals with nectar

Bright petals and nectar commonly attract insects to insect-pollinated flowers.

4. Which process directly increases the number of cells in a growing root tip?
  1. Meiosis
  2. Mitosis
  3. Fertilization
  4. Transpiration

Answer: B. Mitosis

Mitosis produces genetically similar daughter cells and increases cell number during growth.

5. A seedling's dry mass rises from 2.0 g to 5.0 g in 6 days; what is its average dry-mass increase per day?
  1. 0.25 g
  2. 0.40 g
  3. 0.50 g
  4. 3.00 g

Answer: C. 0.50 g

The increase is 5.0 - 2.0 = 3.0 g, and 3.0 g divided by 6 days is 0.50 g per day.
