What type of placentation is seen in sweet pea?
1 Basal
2 Axile
3 Free central
4 Marginal
Explanation:
D Placentation:- The arrangement of ovules within the ovary is known as placentation. In Pisum sativum (sweet pea), the placentation is marginal, in which the placenta develops along the junction of two carpels in a unilocular ovary.

In which of the following aestivation petals one margin covers the other and the margin of next petal is covered by its previous one?
1 Valvate
2 Twisted
3 Imbricate
4 Quincuncial
Explanation:
B Twisted aestivation : One margin of each petal overlap with the margin of next petal e.g. Hibiscus, cotton and lady -finger. Valvate aestivation : Sepals or petals are in a whorl, just touch one another, they do not overlap one another. Example - Calotropis. Imbricate aestivation : When margins of sepals or petals overlap without a clear direction. Quincuncial aestivation : It is aestivation of 5 petals where the margin of 2 petals are exterior, two interior and the fifth is having one margin exterior or interior.

Explanation:
A Aestivation is the arrangement of sepals and petals in floral buds. - Cotton plant shows the twisted aestivation in which one margin of petal overlaps regularly the margin of the adjacent petal and so on. Valvate :- The sepals and petals whorls just touch each other at the margin but do not overlap. Ex- Calotropis. Imbricate - One sepals or petals are totally internal and one are totally external and other are twisted like. e.g.- Gulmohar, Cassia and Legumes Quincuncial - 2 sepals or petals are totaly internal and 2 are totally external and other are twisted like. Ex- Cassia and Delonix.
