After papaya seeds germinate,the hypocotyl elongates and forms a hook.This hook straightens and pulls the cotyledon and the shoot tip of the seedling into the air.This method of embryonic shoot emergence is most similar to shoot emergence in which plant?

Question

Quizplus · Accepted Answer

The method of shoot emergence described in the question is known as epigeal germination, which is characterized by the elongation of the hypocotyl forming a hook, pulling the cotyledons and shoot tip above the soil surface. This type of germination is common in dicot plants such as garden bean. Onion and pea have hypogeal germination, where the cotyledons remain underground, and the shoot grows upwards, and corn has a lateral shoot emergence.
