Question
Explain Epigeal germination
Answers
GPT 3.5
Epigeal germination is a type of seed germination where the cotyledons (embryonic leaves) of the seed emerge above the ground level. It is typically seen in dicotyledonous plants, which have two cotyledons in their seeds.
During epigeal germination, the seedling emerges from the soil with the cotyledons held above the ground on a slender stem called the hypocotyl. The cotyledons, which store nutrients for the growing plant, open up and become green, performing photosynthesis to provide energy for the young plant.
As the seedling continues to grow, the first true leaves begin to form above the cotyledons. These leaves are morphologically different from the cotyledons, and they take over the process of photosynthesis. The cotyledons, having fulfilled their role, eventually wither away.
Epigeal germination is advantageous for plants as it allows the cotyledons to be positioned above the ground where they can receive light for photosynthesis. It also helps in the efficient utilization of space and resources.
Common examples of plants that undergo epigeal germination include beans, peas, tomatoes, and sunflowers.
