Correct answer: C. Hypocotyl

  • A. Radicle
  • B. Epicotyl
  • C. Hypocotyl
  • D. Coleoptile

Explanation

Below the point at which the cotyledons are attached, the embryo axis in a plant is called the "hypocotyl." The hypocotyl is the region of the embryo axis between the attachment point of the cotyledons (seed leaves) and the radicle, which is the embryonic root. The hypocotyl plays a crucial role during seed germination, as it often elongates to lift the cotyledons and the shoot tip (plumule) above the soil surface, allowing the young plant to emerge and initiate photosynthesis.
