How do insects benefit flowering plants?
For self-pollinating flowers, insects move pollen to the parts of the flower that need it. Some insects can carry pollen over long distances, which can help to spread genetic diversity in a plant population.
Why do flowers produce nectar?
Many flowers produce nectar to feed the insects so they will continue to visit, thu s spreading pollen around as they do. Now that you know some plant adaptations, let's check out the other side of the pollination coin: insect adaptations.
What part of the flower does pollen land on?
Through the commotion of the insect crawling on the flower, pollen will occasionally land on the flower's stigma, which is the female part of the flower. Once the pollen grains land on the stigma, pollination has occurred.
What is responsible for the transfer of pollen?
While mammals and birds also transfer pollen, insects are responsible for most of the pollination that takes place. Let's explore insect pollination, or where plant pollen is transferred via insect, in a little more detail. And don't worry, some of those plant terms that have been thrown around will get defined, too.
What is the role of pollinators in plants?
This process ensures fertilization and the development of a seed.
Why do flowers have a fragrance?
Plants have adaptations other than color, too. Some flowers emit a wonderful fragrance to convince insects to visit them. Some, like the voodoo lily, rely on flies, so the odor of this flower is more manure-like than perfume-like.
How much of plants need pollinators?
Around 75% of plant species need the help of a pollinator to get their pollen transferred. Still not convinced that insects are a big deal? Check this out: around one third of the food and drinks you enjoy are produced with the help of a pollinator. And it gets better! Somewhere around $20 billion of products are produced each year in the United States due to the work of pollinators.
What is the tiny yellowish powder that will become sperm and will fertilize the female parts of a plant?
The pollen, which is the tiny, yellowish powder that will become sperm and will fertilize the female parts of a plant, sits on a structure called an anther. Once the insect lands on the flower, it will get pollen all over its body by coming into contact with the anther.

Sunflowers and orchids are the best examples of self-pollinated flowers. Cross-Pollination — Cross-Pollination is the complex type of pollination, ...
What is the process of transferring pollen grains from the anther to the stigma?
What is pollination? Pollination can be defined as the natural process of transferring pollen grains from the anther (male reproductive part) to the stigma (female reproductive part) of a flower. This process can be carried out either within a flower or between flowers of the same plant or flowers of different plants.
What are the two types of pollination?
Based on the transfer of pollen grains, pollination has been classified into two different types: 1 Self Pollination – — Self-pollination is the initial type of pollination, which occurs by transferring the pollen grains directly from anther into the stigma of the same flower. Sunflowers and orchids are the best examples of self-pollinated flowers. 2 Cross-Pollination — Cross-Pollination is the complex type of pollination, during which the pollen grains are transferred from the anther of the flower into the stigma of a different flower. Tulips, dandelions and daffodils are the best examples of a cross-pollinated flower.
What is the name of the small, sticky, and sticky flower that is found hanging out of the petals?
In insect-pollinated flowers, the produced pollen grains are larger in size, sticky and spiny which helps the insect to carry the pollen grains. Stigma. Stigma is feathery or sticky and found hanging out of petals. Stigma is small and is situated deep inside the petals. Stamens.
What is the difference between insect pollinated flowers and wind pollinated flowers?
The wind-pollinated flowers comprise light coloured petals, without a pleasant strong smell. The insect-pollinated flowers comprise brightly coloured petals with a pleasant strong smell. In wind-pollinated flowers, the produced pollen grains are smaller and lighter in weight, which can be carried by the wind easily.

Why are wind pollinated plants dull?
Answer: Wind pollinated plants are adapted in a way so that they can allow the wind to transfer their pollen grains from anther to stigma. These types of plants are not brightly coloured and are very dull because these features of plants are useless in case of wind pollination.
What happens when pollen grains fall in the stigma of other flowers?
In this case, many pollen grains get wasted as they fall in all sorts of places. Those pollen grains which fall in the stigma of other flowers cause pollination.
What is cross pollination?

What are insects pollinated flowers?
Insect Pollinated Flowers. Insect pollinated flowers are those flowers which rely on insects ( e.g. bees, butterflies), birds (e.g. sunbird, hummingbird) and animals (e.g. bats) to transfer the pollen grains from the anther of one flower to the stigma of another flower. Some insect-pollinated flower examples are Sunflowers, Orchids and Buddleja.
Key points
Insect-pollination of flowering plants is responsible for the majority of the world’s flowering diversity and is an essential part of plant reproduction.
Flower structure
Flowering plants reproduce sexually through a process called pollination . The flowers contain male sex organs called stamens and female sex organs called pistils. The male and female sex cells produced from the male and female sex organs must meet for reproduction to begin.
Pollination
Pollination is the act of transferring pollen grains from the male anther of a flower to the female stigma. The aim of most living , including plants, is to produce offspring for the next generation. One of the ways that plants can produce offspring is by making seeds.
Wind and insect pollination
As plants cannot move like animals they must adopt a different method of transferring these pollen grains.
Importance of insects in pollination
Many crops depend on pollination by insects to survive. Bees, butterflies, beetles, moths and flies are all pollinators . Without them, food security would be threatened and there would be a worldwide shortage of fruit; especially apples, plums and pears.
