In which of the following plants, pollen is released before the stigma becomes receptive in the same flower?
1 Solanum
2 Allium
3 Colchicum
4 Datura
Explanation:
B Protandry- It is a condition where stamens are mature earlier than pistils as a result, pollen is released before the stigma becomes receptive in the same flower. For eg. Allium. - Solanum is a large and diverse genus of flowering plants, which include three food crops of high economic imporatance: the potato, tomato and egg plant. - Cochicum is a genus of perennial flowering plants which grow from bulb like corm. - Datura is a genus of nine species of highly poisonous plant that belongs to the nightshade family.

When the margins of sepals or petals overlap one another without any particular direction, the condition is termed as:
1 Vexillary
2 Imbricate
3 Twisted
4 Valvate
Explanation:
B When the margins of sepals or petals overlap one another without any particular direction, the condition is termed as Imbricate. If the margins of the sepals or petals overlap each other without any specific direction- Ex. Cassia.

When the sepals or petals meet by their edges without overlaping the aestivation is :
1 lmbricate
2 valvate
3 twisted
4 axillary
Explanation:
B When the sepals or petals meet by their edge without overlapping the aestivation is valvate. - Opening by valves; as certain capsules and anthers, meeting without overlapping, as the parts of certain buds. Ex- Sepals of Hibiscus, petals of Calotropis and Brassica.

Which of these is an example for zygomorphic flower with imbricate aestivation?
1 Calotropis
2 Mustard
3 Canna
4 Cassia
Explanation:
D Cassia have zygomorphic flower with imbricate aestivation while in mustard, actinomorphic flower occurs. Cassia belongs to family Fabaceae. Because of the irregularity the corolla also has petal that differ from each other in sizes. Ascending imbricate aestivation is found in Cassia and Gulmohur flower that can be divided into two halves from one plane is known as a zygomorphic flower.
