Question

Bisexual, sessile and bracteate flowers develop acropetally in

• A. Raceme
• B. Panicle
• C. Spike
• D. Corymb

Answer 1

The correct option is C Spike

There are two types of inflorescence seen in plants, that is determinate and inderminate inflorescence. In determinate florescence, the youngest flowers are at the bottom of an axis. In inderminate inflorescence, the youngest flowers are at the top of an axis. These include raceme, panicle, spike, corymb, umbel, spadix and head. In raceme, flowers develop between the stem and branch of each leaf along an axis. In panicle, the branched receme has more than one flower. In spike, the flower is sessile and develops from stem. Bisexual, sessile and bracteate flowers develop acropetally in spike. In corymb, pedicels of the upper flowers are shorter than that of the lower flowers

Thus, the correct answer is 'Spike.'
