Detailed explanation-1: -Solution: The mode of arrangement of sepals or petals in floral bud with respect to the other members of the same whorl is known as aestivation. Phyllotaxy is the pattern of arrangement of leaves on the stem or branch. The arrangement of flowers on the floral axis is termed as inflorescence.
Detailed explanation-2: -Aestivation is the mode of arrangement of sepals or petals with respect to the other members of the same whorl.
Detailed explanation-3: -Vexillary aestivation is a special type of aestivation. In valvate aestivation margins of adjacent petals or sepals touch each other at the margin without overlapping.
Detailed explanation-4: -The arrangement of floral leaves in a floral bud is known as aestivation. It occurs in different floral parts like calyx and corolla. The arrangement of leaves in a vegetative bud is known as prefoliation.
Detailed explanation-5: -Aestivation (in botanical terms) is the arrangement of sepals and petals in floral buds with respect to other members of the whorl. It is often confused with vernation, which is the arrangement of scales and new leaves in a leaf bud before it opens. The sepals and petals are collectively known as a perianth.
