AESTIVATION refers to:
AThe arrangement of sepals or petals in floral BUD with respect to other members of the same whorl; types include VALVATE, TWISTED, IMBRICATE
BThe arrangement of stems on a node
CThe arrangement of veins in a leaf
DPollination mode
Answer & Solution
Correct answer: A. The arrangement of sepals or petals in floral BUD with respect to other members of the same whorl; types include VALVATE, TWISTED, IMBRICATE
Aestivation = how sepals/petals are arranged in the bud. Main types: valvate (just touching), twisted (one edge over next), imbricate (overlapping irregularly), and vexillary (in pea family). Phyllotaxy is leaf arrangement; venation is veins; pollination is pollen transfer.
