5 Biology practice questions on Plant reproduction. Questions that assess core concepts and understanding.

Questions

  1. 1.

    In the reproductive cycle of seedless plants such as mosses and ferns, which specialized multicellular structure produces and releases flagellated sperm cells?

    • A) Archegonium
    • B) Sporangium
    • C) Antheridium
    • D) Sorus
  2. 2.

    Which adaptation enables seed plants to achieve fertilization without requiring a film of external water for sperm motility?

    • A) The transport of non-flagellated male gametes through pollen tubes directly to the ovule
    • B) The production of motile flagellated sperm within specialized antheridia
    • C) The release of resistant haploid spores directly into the surrounding soil
    • D) The development of an independent, photosynthetic gametophyte generation
  3. 3.

    In the life cycle of plants exhibiting alternation of generations, which statement correctly describes the gametophyte generation?

    • A) It is diploid and produces haploid spores via meiosis.
    • B) It is diploid and produces haploid gametes via meiosis.
    • C) It is haploid and produces haploid gametes via mitosis.
    • D) It is haploid and produces haploid spores via mitosis.
  4. 4.

    Following successful fertilization in angiosperms, what do the ovule and the surrounding ovary develop into?

    • A) The seed and the fruit wall
    • B) The fruit wall and the seed
    • C) The pollen grain and the seed coat
    • D) The endosperm and the floral receptacle
  5. 5.

    During double fertilization in angiosperms, what are the respective roles of the two sperm cells delivered by the pollen tube?

    • A) One sperm cell fertilizes the egg to produce the endosperm, while the other fertilizes the central cell to produce the diploid zygote.
    • B) Both sperm cells fertilize separate egg cells within the same ovule to generate two genetically identical plant embryos.
    • C) One sperm cell fertilizes a synergid cell to initiate seed coat formation, while the other fertilizes the egg cell to form the zygote.
    • D) One sperm cell fertilizes the egg cell to form a diploid zygote, while the other fuses with the central cell nuclei to form triploid endosperm.
