why in some flowers there is nectar and in some flowers not?

Question

we can feel the presence of nectar in some flowers and in some flowers it is not there. In some flowers we can feel fragrence and in some it is not there.

Answer 1

Nectar, is a sugar-rich liquid produced by the flowers of plants in order to attract pollinating animals.

It is produced in glands generally (but not always) at the base of the perianth, so that pollinators are made to brush the flower's reproductive structures, while accessing the nectar.

While nectar that is produced outside the flower is for the purpose of attracting predatory pollinators. These predatory pollinators (e.g hummingbirds) will eat both the nectar and any plant-eating insects found, thus functioning as 'protectors' to the pollinated flower that will later grow and develop into seeds.

Flowers without nectar are created by the grand design of Allah. One good example is Plumeria (commonly known as Frangipani) that produce flowers with no nectar but are most fragrant at night (to attract sphinx moths). The flowers have no nectar, and simply dupe their pollinators (sphinx moths). The moths inadvertently pollinate them by transferring pollen from flower to flower in their fruitless search for nectar.

Answer 2

Some flowers have nectar, some flowers have fragrance, some have bright colours. All these are meant for pollination. The flowers which have no fragrance have nectar and this nectar attracts insects, birds and so the pollination takes place through these animals.

Answer 3

Nectar attracts insect pollinators, particularly birds. Not all flowers are pollinated by animals, much less birds.

Answer 4

nectar is secreted by a type of special tissues which is the characteristic of orchids,the advanced plants and rarelysome other plants.It is an adaptation to promote crosspollination which is essential for geneticrecombinations which help in origin of species

Answer 5

depends on wat type of pollination the flower requires

if it's insect pollinated, it will require scent to attract insect to stick its gametes.

if it's wind pollinated, it will not emit any scent as it is unneccsary to do so.
