Yes, a flower's lack of scent can turn away a hummingbird, as these birds are often attracted to fragrant flowers. While visual cues, such as bright colors, are significant in attracting hummingbirds, scent also plays a role in their foraging behavior. Flowers that produce a sweet fragrance can signal to hummingbirds that they offer nectar, making them more appealing. However, some hummingbirds may still visit flowers without scent if they are visually attractive and abundant in nectar.
the hummingbird has a special type of beak like a straw to suck nectar out of a flowers.

The hummingbird has an extremely fast metabolism. It lives on the edge of survival. It has adapted in many ways. A hummingbirds has so sense of smell but a very keen eyesight. It can spot its food by seeing brightly colored flowers.These are the flowers that have co-evolved with the hummingbird. They have the high nectar count need by the hummingbird to survive. The hummingbird pays back the favor by pollinating these flowers. It has evolved to have a long beak.This makes it easy to access the nectar from these same brightly colored flowers which generally are tubular in shape. Another adaptation of the hummingbird is its tongue. It has a special forked tongue that allows it to get nectar. Flight is a marvelous adaptation of the hummingbird. It can fly forward, backward, upside down and hover in place. This allows the bird to get nectar from flowers. Hummingbirds also have a semi-hibernation state called Torpor. When weather is cold or there is a lack of food supply , hummingbird will go into torpor in order to stay alive.
That red is not a color that the insects in question see is a reason why bees do not pollinate red gumamela flowers. The non-woody plant in question (Hibiscus rosa-sinensis) may sport orange, red or rose-white flowers. The bright colors and the long tubes tend to be perfect for hummingbirds, whose priority color is red.
Grass flowers' lack of strong fragrances and bright colors is likely related to their method of wind pollination. Wind-pollinated plants do not rely on attracting pollinators with scent or color; instead, they release large amounts of lightweight pollen into the air to be carried by the wind to neighboring flowers. This strategy is more efficient for grass flowers, as it allows for widespread dispersal of pollen for successful pollination.

Flowers with pistils but no stamens are called pistillate flowers or female flowers. These flowers have reproductive structures that include the female reproductive organ (pistil) but lack the male reproductive organ (stamen).
Flowers that do not have either stamens or pistils are referred to as incomplete flowers. These flowers may lack one or both of these reproductive structures, making them unable to fully reproduce on their own.
Angiosperms have flowers and fruit, which are structures that gymnosperms lack. Flowers are reproductive structures that attract pollinators, while fruit develops from the ovary after fertilization to protect and disperse seeds. Gymnosperms, on the other hand, produce seeds that are not enclosed within a fruit and do not have true flowers.
