Answer:
Haploid and diploid life cycle. Haploid male and female cells form together to create a diploid zygote, however when spores or seeds are released (depending on the type of plant) these are once again haploid cells - hence the cycling between cell states
There are choices for this question namely:
<span>movement of oocytes </span>
<span>movement of sperm if present </span>
<span>expelling of the fetus at delivery </span>
<span>all of the above
</span>
The correct answer is "all of the above". The smooth muscle layers in the female reproductive tract facilitates the movement of oocytes from the ampulla of the fallopian tube to the uterus. If sperm is present, the contraction of smooth muscle in the uterus will propel the sperm towards the fallopian tubes where it can fertilize the ovum. At delivery, uterine contractions (along with an adequate pelvis) facilitate the delivery of the fetus; without which the labor will be dysfunctional or prolonged and this is called dystocia.

Answer:
when vesicles cluster at the future plane of division
Explanation:
Cytokinesis is the process whereby the cytoplasm of a cell divides into two. This process of cytokinesis occurs after nuclear division i.e. division of the nucleus. However, cytokinesis differs in plant and animal cells.
In plant cells, the separation of the cytoplasm involves the formation of a cell plate. The process begins when a structure called phragmoplasts carry vesicles to the cell plate. In other words, vesicles cluster at the future plane of division (cell plate).
