Ovules are found attached at basal placentation in:
1 Liliaceae
2 Malvaceae
3 Asteraceae
4 Cucurbitaceae
Explanation:
The ovary where the placenta expands from its base and a single ovule appears attached to the base has a basal placentation. It is mostly seen in Asteraceae (marigold and sunflower)

Identify the correct statement,
1 Only megaspore present towards chalazal end is functional
2 3 megaspore present towards chalazal end degenerate gradually
3 Each megaspore mother cell, directly develops into a measpore
4 Each female gametophyte is 7 -celled & 7 - nucleated structure.
Explanation:
The megaspore present towards the chalazal end is functional megaspore, remaining ones degenerate.

Functional megaspore in an angiosperm develops into?
1 Endosperm
2 Embryo sac
3 Embryo
4 Ovule
Explanation:
Process of formation of megaspores from megaspore mother cell (MMC) is called Megasporogenesis. Megaspore mother cell undergoes meiosis to form 4 haploid megaspores.Out of four megaspores, 3 gets degenerated and one megaspore enlarges to become functional megaspore. Functional megaspore develops into female gametophyte or embryo sac in angiosperms.
