type of symmetry of floral whorls is this?
Bimerous
Trimerous
Tetramerous
Pentamerous​

Answer 1

Answer:

Flower is a reproductive organ of the angiosperm plant that contains thalamus and floral leaves. A typical flower consists of four types of floral leaves called sepals, petals, stamens and carpels in distinct whorls normally known as calyx, corolla, androecium and gynoecium respectively. A flower in which all the four whorls are present (Sepal, Petal, Carpels, Stamens) are called as complete.The stalk of a flower is called as pedicel that holds the actual flower up in the air.

If a flower having both male and female sex organs are called bisexual and a flower having either only male or female organs is called unisexual. A flower having bract at its tip is called bracteate and without bracts is called ebracteate. A flower without a stalk or pedicel is called sessile and a flower having a stalk is called pedicellate. A flower may be trimerous, tetramerous or pentamerous when the floral leaves of each whorl are in multiple of 3, 4 or 5, respectively.

Based on the symmetry of the flowers can be described in to following types:

1. Actinomorphic: Flowers can be divided into two halves through any vertical plane.

2. Zygomorphic: Flowers can be divided into two equal halves only along one vertical plane.

3. Asymmetrical: Flowers which cannot be divided into equal halves by any plane.
