Q. Pick out the wrong statement, and correct it.
1). In polygonum type of ovule, the functional haploid megaspore enlarge in size and by means of 3 successive mitotic divisions, give rise to eight nucleated embryo sac.
2). Sporopollenin makes the exine of spores and pollen grains of plants providing resistance to biodegradation.
3). Pollen kit material is secreted by tapetum.
4). Occurance of more than 4 spores from a spore mother cell is called polyspory.

Dear student,

The incorrect statement is (1) it give rise to Seven nucleated embryo sac not Eight ​.
In polygonum type of ovule, the functional haploid megaspore enlarge in size and by means of 3 successive mitotic divisions, give rise to Seven nucleated embryo sac consisting of three antipodal cells, one central cell formed by two polar nuclei, two synergid cells, and the egg cell.

Regards.
