Question

Describe the nectar feature of Entomophilous flowers.

Answer 1

Nectar is a sugar-rich liquid produced by plants in glands known as nectaries or nectarines, either within the flowers to attract pollinating animals, or extrafloral nectaries to provide a nutrient source to animal mutualists, who in turn protect herbivores.

Complete answer:
A nectary, also known as a nectarine, is a type of floral tissue that produces nectar, oil, or scent. It is one of several secretory floral structures that include elaiophores and osmophores. These structures are used to attract pollinators, which can include insects like bees and moths, as well as vertebrates like hummingbirds and bats. Nectaries can appear on any part of the flower, but they could also be a modified part or a new structure.
Many flowers produce nectar, which is a sugary liquid or honey. The nectary is the gland that produces nectar. This can be found on the thalamus, between petals and stamens, and between androecium and gynoecium, among other places. It can even be found on the involucre of bracts, as in Poinsettia cyathium.
Flowers that are pollinated by insects are known as entomophilous flowers. Honey bees are the insects among the options in the question. Because honey bees pollinate entomophilous flowers, they are related to honey bees.
Most gamopetalous flowers have nectar glands that produce nectar for insects that pollinate the flowers by accident. Many flowers become fleshy, produce more pollen, and serve as food for insects in addition to these three characteristics. Pollen grains have spinocent walls that allow them to cling to insects' bodies. They are also yellow in color due to the presence of sporopollenin in their walls.

Note:
Sugars in various proportions of sucrose, glucose, and fructose are the main ingredients in nectar. In addition, nectars contain a variety of other phytochemicals that attract pollinators while repelling predators. Some species are attracted to carbohydrates, amino acids, and volatiles, whereas alkaloids and polyphenols appear to protect them.
