What else can I help you with?
What is the sticky hairy part of the plant?
The sticky hairy part of a plant is called the trichome. Trichomes can help protect the plant from predators, reduce water loss, and aid in trapping insects for pollination or capturing prey.
What is the structure that develops into a pollen grain?
First pollen falls from a male cone onto a female cone. In time a sperm cell and an egg cell join together in an ovule on the female cone
How might a bee transfer pollen from the anthor to a stigma?
A bee transfers pollen from the anther to a stigma by visiting flowers to collect nectar and pollen as food. While foraging, pollen grains stick to the bee's body due to static electricity and the hairy texture of their bodies. When the bee moves to another flower, some of this pollen is brushed off onto the stigma, facilitating cross-pollination, which is crucial for plant reproduction. This process enhances genetic diversity in plants and promotes healthy ecosystems.
Why does plants have petals?
Plants flower for one simple reason: pollination. The bright coloured flowers and the scent attracts insects towards them. While the insect is sucking the nectar, the pollen grains get attached to its hairy skin. Then this insect visits another flower and the pollen grains might get deposited on the stigma. There you go, the flower has been fertilized and very soon, it wil become a fruit. Now you will ask why does it become a fruit? Here's why: To distribute its seeds.
What are the agents in pollination?
Agents of PollinationIntroduction of agents of pollinationWhen the pollen grains are shed from anther, they are disseminated by arios agencies. Some of them may, by one means or another, finally reached the stigma of a pistil, either of same or another flower. This transfer of pollen from anther to stigma is called pollination. Agents of pollination are wind, water, insects, birds and bats. Description of Agents of PollinationWind (anemophily): Wind is one of the most important agents of pollination. Pollination brought about through agency of wind in plants is called anemophily. Wind pollinated plants are coconut palm, date palm, cannabis, maize, grasses etc. exhibit the following characters which favour the wind pollination.a) Wind pollinated flowers are inconspicuous and not showy.b) They are devoid of scent, nectar etc.c) The pollen grains are dry and unwettable.d) The anemophilous plants grow in large groups to ensure pollination.e) To catch the pollen grains, the stigma become sticky, hairy, and feathery or branched.2. Water (Hydrophily): Pollination brought about through the agency of water in plants especially submerged plants is termed hydrophily. Examples are Hydrilla, Ceratophyllum, Zostera and Vallisneria are some of the water pollinated plants.3. Insects(Entomophily): Inset pollinated flowers possess following characteristic featuresa) The insect pollinated flowers are fragrant and omit sent and odour. Example Cestrum, Jasmine etc. Rafflesia gives out obnoxious and repelling odour.b) The insect pollinated flowers are beautifully coloured. In flowers, mostly petals are brightly coloured.c) The nectariferous glands produce nectar for feeding the visiting insects.d) To catch the pollen grains, the stigmas become sticky.4. Birds (ornithophily): Ornithophilous flowers differ in number of respects from entomophilous flowers. These kind of flowers are generally scentless. The flowers are usually large in size. They are also beautifully coloured with colour contrasts and are common colours liked by birds.5. Bats (Chiropterophily): The flowers of Kigella pinnata, Durio, Antocephalus are pollinated by bats. The bats hold on to the freely exposed, large and relatively tough flowers, which open in the evening or night. Bats are nocturnal animals and transport pollen over long distances. They usually give off a strong scent like that of rotting fruits. Bats also feed on the copious nectar and pollen which is produced in plenty as compared bird pollinated flowers.
What do we call the sticky or hairy part of the flower were the pollen lands?
we call it stigma
What helps the pollen grains to stay on the tip of the style after they land there?
sticky stigma
What part of the bee does the pollen stick to?
its legs because there hairy which helps the pollen stick to them
How a flower is likely to be cross-pollinated by a bee?
when an insect visits a flower to feed on the nectar, some pollen grains from the anther stick to the hairy body of the insect. the pollen grains are brushed off onto the stigma when the insect visits another flower. examples of the flower:wild orchid balsam rose buttercup
How does it help the flower that insects have hairy legs?
Insects with hairy legs can effectively collect and transfer pollen between flowers, enhancing pollination. The hairs trap pollen grains as the insect moves from flower to flower, increasing the chances of fertilization and seed production. This mutualistic relationship benefits both the flowers, which rely on pollinators for reproduction, and the insects, which obtain food in the form of nectar and pollen. Overall, the hairy legs of insects play a crucial role in the reproductive success of many flowering plants.
How the bees catches some of the pollen grains and drops them on another flower and how Pollination occurs?
The rear legs of the bees are hairy. When they enter a flower pollen grain being light attaches itself on the hairy legs. It is transferred to another flower when theres some frequent movement of the bee,either by flaping their wings or walkin in out the flower. This inturn results to cross poliination.
What is the sticky hairy part of the plant?
The sticky hairy part of a plant is called the trichome. Trichomes can help protect the plant from predators, reduce water loss, and aid in trapping insects for pollination or capturing prey.

How are seeds usually dispersed?
when a hairy animal is moving... burdock is very sticky type and it sticks on
What kind of food should you eat before sporting events?
long, warm, hairy and sticky foods
How do bees carry pollen?
Bees collect pollen on their hairy bodies as they move from flower to flower. The pollen sticks to their bodies and is then carried back to the hive in special pollen baskets on their hind legs. This pollen is used as food for the bees and to help pollinate other flowers.
