Common mistakes in Pistil, megasporangium and embryo sac
Recorded against questions in this topic that are not shown above, so none of these points at an answer you can see on this page.
- Assuming every nucleus must occupy a separate cell.
- Confuses the chalazal end with the micropylar opening.
- Counts the two polar nuclei as two separate cells.
- Equates number of nuclei with number of cells.
