Question

The division of zygote in the development of crucifer type embryo is

• A. Transverse
• B. Vertical
• C. Both A and B
• D. None of the above

Answer 1

The correct option is A Transverse

The zygote in crucifers divides transversally to produce terminal and basal cells. The terminal cells divides vertically to produce 4 celled embryo and basal cell produces suspensors and in some plant produces hypocotyl. Each four cell divides transversally and produces 8 celled embryo. The 8 cells further divides to form inner and outer cells of the embryo. Thus, the correct answer is option A.
