Hello. This question is incomplete. The full question is:
"Examination of slide will show that a few nuclei do not appear next to a cell wall in onion cell. Could you explain that observation?"
Answer:
You are visualizing the onion cell during mitosis interphase. At that time, cells may have multiple nuclei and some of them may not be visible near the cell wall.
Explanation:
Experiments with onion roots are common when we want to visualize the phases of the cell cycle or to visualize chromosomes and cell nuclei.
If after the experiment with an onion cell you are unable to visualize the cell nuclei near the cell wall, it means that you are visualizing the cells during the interphase of mitosis. At that time, cells may have multiple nuclei and some of them may not be seen near the cell wall.
The onion root tips are very famous for observing the distinct phases of mitosis as the chromosomes are very large and get very dark when stained.
The epidermal cells in the onion take place cell division (cytokinesis) and mitosis (nuclear division). The interphase cell usually possesses one or number of nuclei, thus, a few nuclei are not witnessed adjacent to a cell wall.

Answer:
Embryology
Explanation:
Comparative Embryology is the field of embryology. It deals with the study and comparision of the development, morphology, anatomy, physiology and genetic make of embryos belonging to different species. It also help in determining the evolutionary relatedness of the embryos of the previously existing species and present day organisms on the basis of the similarities and differences in the embryo features. All embryos pass through the stage of few to multiple celled zygotes. The differentiation of the zygote results in the clump of cells called as morulas then into hollow balls of cells called as blastulas. The differentiation of blastula leads to the creation of organs of the body.
