Which of the following floral part is important for pollination?
Corolla
Calyx
Pedicel
Staminode
Answers
pedicel ir the correct answer
Answer:Nectar and pollen grains are important floral rewards to the animal pollinators such as moths, butterflies, wasps, bees, birds, etc.
Explanation:Parts of the Flower
Each flower normally has four floral whorls, viz., calyx, corolla, androecium, and gynoecium. Let us look at each of these parts individually.
i) Calyx (Sepals)
The calyx may be gamosepalous (sepals united) or polysepalous (sepals free). Generally, sepals are green, leaf-like and protect the flower in the bud stage. They form the outermost whorl of the flower.
ii) Corolla (Petals)
Petals are usually brightly coloured to attract insects for pollination. Yes! That is why the flowers are coloured and attractive! Corolla may be also free (gamopetalous) or united (polypetalous). The shape and colour of corolla vary greatly in plants. It may be tubular, bell-shaped, funnel-shaped or wheel-shaped.
iii) Androecium (Stamens)
This part of the flower represents the male reproductive organ. Each stamen consists of a stalk or a filament and an anther. Each anther is usually bilobed and each lobe has two chambers, the pollen-sacs. The pollen grains are produced in pollen-sacs. A staminode is a sterile stamen.
When stamens are attached to the petals, they are called epipetalous. The examples of this type include brinjal. When stamens are attached to the perianth, they are called epiphyllous. Lily is an example of this type. Flowers are also classified on the basis of the fusion of stamen. They are divided into the following types.
Polyandrous: In this, the stamens in a flower remain free.
Monadelphous: In these, the stamens are united into one bundle. Examples include China rose.
Diadelphous: These have the stamens united into two bundles. Examples include pea.
Polyadelphous: In Polyadelphous, the stamens are united into more than two bundles. Examples include citrus. There may be a variation in the length of filaments within a flower, as in Salvia and mustard.
