Question

Which part of embryo comes out first during seed germination?

• A. Radicle
• B. Plumule
• C. Hypocotyl
• D. Epicotyl

Answer 1

The correct option is A Radicle

The fleshy round structure/s on embryonic axis that contains reserve food material is known as cotyledon. Radicle is present on the micropylar end of embryonic axis while plumule is present on the opposite extreme. Hypocotyl is the part of embryonic axis between radicle and cotyledonary node. Likewise, epicotyl forms the part of embryonic axis between plumule and cotyledonary node. Being intercalary part, hypocotyl and epicotyl do not comes out during seed germination which makes options C and D incorrect. Splitting of seed coat makes the radicle to come out first and form tap root. This makes option A correct and option B incorrect.

Thus, the correct answer is option A.
