In angiosperms, the functional megaspore in the linear tetrad is generally
Open in App
Solution
The correct option is C Fourth from micropylar
Monosporic development
The megaspore mother cell divides by meiosis to produce four megaspores. In monosporic development, one of the four four megaspores formed remain functional. The remaining three megaspores degenerate.
Location of functional megaspore
The functional one is situated at the completely opposite end of the micropyle, i.e., it is the fourth cell of the tetrad from the micropylar end.
Final answer
(D) Fourth from micropylar
