Enlist adaptations of hydrophilous flower and entomophilous flower.
Answers
Answer:
◆The floral adaptations of hydrophilous flowers are:
●Flowers are colourless, small, inconspicuous without nectar and fragrance.
●Pollen grains are long, ribbon-like structures which are carried with current of water.
●The pollen grains are light but covered with wax, in order to protect them from wetting.
◆Some of the adaptations of entomophilous flowers are the following;
●Very conspicuous flowers with brightly coloured petals and perianths
●Small flowers aggregate into inflorescence to become conspicuous.
●Flowers are usually scented to attract insects.
●Flowers have nectaries to produce and store nectar that provides food for insects.
●Pollen grains are usually rough-surfaced and sticky so that they can easily get adhered to the insect body.
Insects can carry pollen grains from anthers of one flower and deposit them exactly on the stigma of another flower. Insects visit flowers to feed pollen and nectar, to deposit their eggs, in search for shelter or for unknown reasons. In order to attract insects, entomo-philous flowers have large and brightly coloured petals. If flowers are grouped into conspicuous inflorescence with fragrance. Insect visitors show a preference for certain colours. Bees, in general, prefer blue colour, butterflies prefer red colour, and certain other flies prefer brown or purple colour.
