A pea flower has five petals. The largest petal overlaps the next two lateral petals which in turn overlap the two remaining small anterior petals. This type of arrangement of petals is known as vaxillary aestivation.
What is the arrangement of the petal?
The mode of arrangement of sepals or petals in a floral bud is known as aestivation. Draw the various types of aestivation possible for a typical pentamerous flower.
How many petals are in peas?
five petals
Pea flowers are made up of five petals that are of different sizes and shapes (and occasionally different colors as well). The diagram at right shows a peanut (Arachis hypogaea) flower (another member of the Pea Family), that identifies the various flower parts.
What is the structure of a pea plant?
The largest and the outermost one is the standard or vexillum, two lateral petals are wings or alae, and the innermost two, called keel or carina, unite to form a boat-shaped body. Aestivation is vexillary. Androecium consists of ten stamens, nine united to form a bundle, one remaining free, diadelphous.
What is aestivation in pea plant?
Aestivation is the manner in which petals or sepals are arranged in a flower bud with respect to the other members of the same whorl. Five types of aestivations are present in the plants. They are Valvate, twisted, imbricate, vexillary and quincuncial aestivation.
How are flower petals arranged?
The petals of flowers are arranged in Fibonacci sequence. The seeds of sunflower follow a Fibonacci pattern. The combs of honeybees usually sum up to a Fibonacci number. Snail shells are Fibonacci in pattern.
What is the arrangement of petals of sunflower?
This type of floret takes the form of petals set in actinomorphic arrangement, being radially symmetric and generally containing pistils and stamens.
What is the leaf arrangement on a pea plant?
Pea Leaf Development
The mature wild-type pea leaf shown in Figure 1A is compound pinnate, consisting of a basal pair of foliaceous stipules, a pair of proximal leaflets, two pairs of distal tendrils, and a terminal tendril.

Flower Appearance
In the single form, each flower has five unequal petals. The broad, topmost petal, called the standard, generally has slightly curved edges. It is flanked by two outer petals that look like wings and protect the remaining pair of petals, which form a central ridged structure, known as a keel.
Which type of flower are present in pea?

What structural features do pea plants flower?
Each pea plant flower has both male and female parts. The anther is part of the stamen, the male structure that produces male gametes (pollen). The stigma is part of the pistil, the female structure that produces female gametes and guides the pollen grains to them.

What is a pea plant called?

Which plant shows Valvate aestivation?
Calotropis plant
Note: Valvate aestivation is seen in the Calotropis plant, imbricate aestivation is seen in Cassia and Gulmohar, and vexillary aestivation is seen in the pea and bean flowers.
What are the 4 types of aestivation?
Types of Aestivation
- Valvate. In this type of arrangement, the sepals and petals whorls just touch each other at the margin but do not overlap.
- Imbricate. In this arrangement, the sepals and petals overlap each other but not in any regular manner or in a nonspecific direction.
- Twisted.
- Vexillary.
- Quincuncial.
