Question

A number of sessile flowers grow on a suppressed peduncle forming a globose inflorescence is called?
A. Catkin
B. Corymb
C. Umbel
D. Capitate

Answer 1

Hint: A group of flowers arranged on a stem that is composed of the main branch or a complex arrangement of branches is known as inflorescence. Inflorescences can be either simple (single) or complex (panicle). The rachis can be single, composite, umbel, spike, or raceme.

Complete answer:
Catkin is the pendulous spike in leaf hub which bears unisexual blossoms. It is a sort of racemose inflorescence. The model is oak.
-Corymb in which the primary pivot is short and lower blossoms have long pedicels than upper ones with the goal that all the blossoms are brought pretty much to a similar level. It is a sort of racemose inflorescence. The model is iberis.
-Umbel in which the primary hub is decreased definitely and all blossoms give off an impression of being emerging from a similar point. It is a kind of racemose inflorescence. The model is hypocotyl.
-Capitate in which an enormous number of sessile blossoms develop from a smothered rachis offering ascend to a pretty much globose structure. The model is a mimosa.

The right option is "D", i.e., (Capitate).

Note: In this type, a cluster of dense sessile flowers arise upon a compressed rachis; thereby giving rise to a somewhat globose structure. e.g., Mimosa pudica. The white head comprises many slim, white blossoms, the pedicels (bloom stems) of which all join at one spot with the goal that the blossoms structure such a circle. You would call this inflorescence type a globose head, "globose" simply meaning circular, similar to a globe.
