Question

An egg cell of a plant is contained in a/an present in an ovary.
A. Ovule
B. Stamen
C. Style
D. Stigma

Answer 1

In plant seeds, the structure ovule contains female reproductive cells. They contain three parts namely- integument (which forms the outer layer), nucellus (it is the remnant of the megasporangium), and the female gametophyte (which is formed through haploid megaspores) which is in the center.

Complete answer: Ovule- flowering plants have ovule which is located inside the gynoecium which is the portion of the flower. The gynoecium produces one or more ovules which becomes the wall of the fruit. There is a placenta-like structure called funiculus which is a stalk-like structure that is attached to the ovary.
Stamen- This is the male reproductive organ of the flower. They produce pollen. Stamen has two parts-stalk and another. The stalk can also be called as filament. Anther has microsporangia and each of these contains pollen mother cells. They undergo meiosis and produce pollen grains.
Style- the style structure is found in the flower. It is slender, long which connects the ovary and the stigma. Stigma is present on top of style which is sticky and has pollen deposited. The ovary is present at the bottom of the style and has ovules which contain egg cells.
Stigma- Stigma along with style and ovary makes the pistil which is a female part of the gynoecium. Stigma is a distinct part of the style.
Hence the answer is option A, ovule.

Note: Ovule is the part and will give rise to female reproductive cells. They consist of female gametophyte which gives the egg cells for fertilization. The male reproductive part is the stamen. The female reproductive part is the stigma that receives pollen and style is the stalk of the carpel.
