Oenothera type of female gametophyte is always
1 8 nucleate and 7 celled
2 16 nucleate and 13 celled
3 8 nucleate and 8 celled
4 4 nucleate and 4 celled
Explanation:
Oenothera type of female gametophyte or embryo sac is always 4 nucleate and 4 celled. It is monosporic and develops from the micropylar megaspore. Out of four megaspore, instead of innermost megaspore, the micropylar megaspore remains functional from which it develop. The functional megaspore undergoes two successive divisions along with it and forms 4 nuclei.

The archesporium of ovule is:
1 single celled lateral
2 single celled hypodermal
3 single celled central
4 single celled terminal
Explanation:
Generally archesporium in an ovule is single celled and hypodermal in origin. A group of cell from which a spore mother cell developed is called archesporium. The archesporial cells functions directly as a megaspore mother cell in the tenuinucellate ovule whereas it divides to form on outer parietal cell and inner primary sporogenous cell in the crassinucellate ovule.

The tissue which attaches the ovules inside the ovary is:
1 placenta
2 chalaza
3 funicle
4 hilum
Explanation:
The tissue which attaches the ovules inside the ovary is called placenta. It is cushion or swollen region in the ovary. Funicle is the stalk that attaches an ovule with that of placenta in the ovary of flowering plants. Hilum is the region where the body of the ovule fuses with funicle.

Micropyle occurs in
1 1,2 and 3 are correct.
2 1 and 2 are correct.
3 2 and 4 are correct.
4 1 and 3 are correct.
Explanation:
Micropyle occurs in ovule which is a part of ovary. After fertilization ovule is converted into seed and ovary converted into the fruit. So, ultimately micropyle becomes a part of seed. Stigma is a receptive portion of female reproductive part (pistil) of the flower.
