Question

female gametophyte of Gnetum​

Answer 1

Explanation:

The sporogenous cells function as megaspore mother cells which undergo meiotic division. Since no walls are laid down after meiotic division of megaspore mother cells, all the four nuclei remain within the mother cell to form a tetranucleate coenomegaspore. Thus, the female gametophyte of Gnetum is tetrasporic

Answer 2

Answer:

The primary sporogenous cells divide to form 8-20 sporogenous cells which are linearly arranged. ... Since no walls are laid down after meiotic division of megaspore mother cells, all the four nuclei remain within the mother cell to form a tetranucleate coenomegaspore. Thus,

the female gametophyte of Gnetum is tetrasporic
