Question

Explain the helobial type of endosperm with suitable examples.

Answer 1

1. It occurs in the order Helobiales of monocotyledons.
2. In this case, the first division of the primary endosperm nucleus is followed by a transverse wall, which divides the cell unequally.
3. The smaller cell is called the chalazal cell, and the larger cell is the micropylar cell.
4. Then the nuclei in each cell divide by free nuclear divisions, and then walls develop between nuclei in the micropylar chamber.
5. It is intermediate between cellular and nuclear type endosperm, e.g., Asphodelus.
