Class 12 Biology Reproduction Sexual reproduction in Flowering Plants



The basal cell in a zygote
(a)
Develops into the root of the embryo
(b)
Forms the suspensor that anchors the embryo and transfers nutrients
(c)
Results from the fertilization of polar and sperm nuclei and develops into the endosperm
(d)
Divides to form the two cotyledons of the proembryo
Correct answer: (b) 
Solution: A zygote is the cell formed when two gametes fuse during fertilization. The DNA material from the two cells is combined in the resulting zygote. The zygote undergoes an asymmetric transverse cell division that gives rise to two cells - a small apical cell resting above a large basal cell. The large basal cell is on the bottom and consists of a large vacuole and gives rise to the hypophysis and the suspensor. The suspensor connects the endosperm to an embryo and helps in transfer of nutrients
So the correct answer is 'forms the suspensor that anchors the embryo and transfers nutrients'
