Solution

Germination:

  1. The beginning of growth of the seed into a new plant is called germination.
  2. The embryo formed is later differentiated into plumule (shoot part), radicle (root part) and cotyledons.
  3. Shoot portion between cotyledon and plumule is known as epicotyl.
  4. Root portion between cotyledon and the radicle is termed as hypocotyl.

Types of germination:

  1. Hypogeal germination: The epicotyl elongates and the cotyledon remain below the soil. Maize is an example of hypogeal germination.
  2. Epigeal germination: The hypocotyl elongates and the cotyledon is brought above the soil surface. Bean is an example of epigeal germination.

Final answer: Maize : Hypogeal :: Bean: Epigeal
