Identify the correct sequence of mature embryo formation from zygote.
(A) Heart-shaped embryo
(B) Globular embryo
(C) Proembryo
(D) Mature embryo
Choose the correct answer from the options given below.
Answer & explanation
Correct answer: option 4
The correct answer is Option (4) → (C), (B), (A), (D)
(C) Proembryo — first. The zygote lies at the micropylar end of the embryo sac. Its first divisions give a small group of cells, the proembryo.
(B) Globular embryo — second. The cells keep dividing and the embryo becomes a round ball of cells.
(A) Heart-shaped embryo — third. In a dicot, two cotyledons begin to grow at the top of the globular embryo. The two lobes give it the shape of a heart.
(D) Mature embryo — last. The embryo now has its full set of parts: the cotyledons and the embryonal axis with the plumule and the radicle.
