The hypocotyl is long and curved down

|
|
Germination takes place above the ground

Detailed explanation-1: -Hypogeal germination implies that the cotyledons stay below the ground. The epicotyl (part of the stem above the cotyledon) grows, while the hypocotyl (part of the stem below the cotyledon) remains the same in length. In this way, the epicotyl pushes the plumule above the ground.
Detailed explanation-2: -Cotyledons are capable of storing nutrients and performing photosynthesis and provide a major proportion of matter needed for seedling growth and development until the first true leaf becomes a significant exporter of photosynthates (Zhang et al., 2008; Zheng et al., 2011).
Detailed explanation-3: -Hypogeal Cotyledons: Meaning and Function These cotyledons serve as food storage for the plant instead of producing food through photosynthesis. This type of cotyledon is common in monocots.
Detailed explanation-4: -angiosperm seed germination In hypogeous germination, the hypocotyl remains short and the cotyledons do not emerge from the seed but rather force the radicle and epicotyl axis to elongate out of the seed coat. The seed, with the enclosed cotyledons, remains underground, and the epicotyl grows up through the…
