The type of germination in mungbean seed is _____.

Correct option is A

The correct answer is (a) Epigeal

Explanation:
• Epigeal germination is a type of seed germination where the cotyledons (seed leaves) are pushed above the soil surface.
• This happens due to the rapid elongation of the hypocotyl (the part of the stem below the cotyledons).
• Mungbean (Vigna radiata) is a classic example of a pulse that exhibits epigeal germination.
• Once the cotyledons reach the surface, they may turn green and perform photosynthesis for a short period.
• Other examples include cotton, castor, and onion.

Information Booster:
• In Hypogeal germination, the epicotyl elongates, and the cotyledons remain underground (e.g., pea, gram, maize).
• Germination type is an important diagnostic feature in plant science.

Additional Knowledge:
Hypogeal (Option b)
• Seen in plants like Pea and Gram where cotyledons stay in the soil.

Hypo-epigeal (Option c)
• This is not a standard scientific term for primary germination types.

Epi-hypogeal (Option d)
• This is not a standard scientific term used in seed biology.

So the correct answer is (a)
