Question

Trimerous condition of floral whorls is characteristic of?

Answer 1

The flower is a particularly dense shoot of an angiosperm plant in which the shoot apical meristem gets changed into botanical meristem for bringing out sexual generation through the reformist specialization of leaves into flower extremities. Like a branch, it might create in the axil of a little leaf-like structure called a bract.

Complete answer:
A flower without a stalk or pedicel is called sessile and a flower having a tail is called pedicellate. A flower might be trimerous, tetramerous, or pentamerous when the botanical leaves of every whorl are in multiple. Trimerous flowers have sepals, petals, and so forth in threes. Numerous monocots have this kind of flower. Iridaceae have three guidelines and three falls, Hemerocallis have two arrangements of three petals, Orchids have three sepals and three petals, and so on.

Note: Merosity (from the greek "méros," which signifies "having parts") alludes to the number of segment parts in an unmistakable whorl of a plant structure. The term may likewise be utilized to allude to the number of leaves in a leaf whorl. In nature, five or three sections for each whorl have the most elevated recurrence of the event, yet four or two sections for every whorl are normal. Know that two sequential whorls of dimerous petals are regularly confused with tetramerous petals. If the whorls in a flower have a similar merosity, the flower is supposed to be isomerous. Otherwise, the flower is anisomerous.
