What is keel in pea plant?
structure of sweet pea flower
usually fused and form a keel that encloses the stamens and pistil. The whole design is adapted for pollination by insects or, in a few members, by hummingbirds. Sweet nectar, to which the insects are cued by coloured petals, is the usual pollinator attractant.
In which flower keel is present?
Keel is characteristic of the flower of bean. Bean blossoms with this configuration are said to be papilionaceous. The bean or legume family is one of the most common plant families.
Is tomato a keel?
Tomatoes are developed from the ovary. Therefore, they also do not possess keel.
Which aestivation is found in peas?
Vexillary
Hence, the correct answer is ‘Vexillary‘.
What is the function of keel petal?
Keel-flowers have evolved structures and mechanisms to protect their pollen and enhance pollen removal by pollinators.
What is keel in biology?
A keel or carina (plural carinae) in bird anatomy is an extension of the sternum (breastbone) which runs axially along the midline of the sternum and extends outward, perpendicular to the plane of the ribs.
On which side of the flower do the flowers of pea have the keel petals?
– The two anterior petals are called keel which fused enclosing stamens and carpels. – The keel is the innermost petal, also called as Carina.
Which of the following flowers has keel as its characteristic feature *?
Indigofera shows the presence of keel.
Does Gulmohar have keel?

What is the Placentation of pea?
Marginal
Hence, the correct answer is ‘Marginal‘
How are petals arranged in pea plant?
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.
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 is vexillum in flower?
Vexillum is used to refer to the standard, large posterior petals of papilionaceous flowers (corolla). The posterior large bilobed petal of the papilionaceous corolla is called standard or vexillum. They overlap the two smaller lateral petals known as alae or wings.
What are called petals?
Petals (collectively called the corolla) are also sterile floral parts that usually function as visually conspicuous elements serving to attract specific pollinators to the flower. The calyx and the corolla together are referred to as the perianth.
What is a wing petal?
opened, two lateral petals called wings, and two lower petals that are usually fused and form a keel that encloses the stamens and pistil. The whole design is adapted for pollination by insects or, in a few members, by hummingbirds.
In which bird keel is absent in sternum?
example, flying birds have a keel—a ridge on the sternum, or breastbone, which is a main site of attachment for flight muscles. Ratites do not possess this keel, and its absence is one reason why the group’s muscles are unsuitable for flight.
Do ducks have a keel?
The skeleton of waterfowl is uniquely structured. Fusion and strutlike reinforcement of hollow bones make the skeleton both lightweight and powerful, enabling it to withstand stress and support large muscles. The breastbone includes a large keel that anchors major flight muscles.
Is keel related to Corolla?
Petals: A petal found in papilionaceous corolla is keel. Butterfly-like with one posterior standard is Papilionaceous type of corolla . It has two lateral wings, two inner and smaller keels.
