How is lalang plant pollinated?
The lalang plant is primarily pollinated by wind, as it produces anthers that release pollen grains that are carried by air currents to reach the stigmas of other lalang plants for fertilization. This form of pollination is known as anemophily.
Where do Wind pollinated usually have their anthers?
Wind-pollinated plants typically have their anthers positioned outside the flowers, often on long filaments, to facilitate the release of pollen into the air. This arrangement maximizes exposure to wind, allowing pollen to be easily carried to other flowers. Additionally, these plants often produce large quantities of lightweight pollen to increase the chances of successful fertilization.
How might having the anther atop a tall filament make it more likely plants will be pollinated?
Having the anther atop a tall filament increases the chances of pollen being carried away by wind or by pollinators such as bees or butterflies. This positioning also reduces the likelihood of self-pollination and promotes cross-pollination, increasing genetic diversity within the plant population.
Where are pollen grains produced?
pollen grains are produced in pollen sac of anthers which are present on the male gamets of flower
What are the anthers like in insect pollinated plants?
In insect-pollinated plants, the anthers are typically positioned in a way that makes it easy for visiting insects to come in contact with them. They are often located at a height and in a position where the insects can brush against them while foraging for nectar or pollen. This helps facilitate efficient pollen transfer between flowers.
What is the use of protruding and easily movable anthers?
protruding and easily movable anthers help in wind pollination.
How is lalang plant pollinated?
The lalang plant is primarily pollinated by wind, as it produces anthers that release pollen grains that are carried by air currents to reach the stigmas of other lalang plants for fertilization. This form of pollination is known as anemophily.
How would you make sure that a seed was produced from 2 plants that you wanted to breed?
remove the anthers or stigmas of the two plants to prevent accidental or self-pollination after you have hand pollinated them
Do wind pollinated flowers have large anthers?
yes
When are the anthers of one plant removed so it cannot self-pollinate?
Anthers can be removed from a plant before they release pollen to prevent self-pollination. This can be done in controlled breeding programs to promote outcrossing or hybridization. Removing the anthers ensures that the plant can only be pollinated by pollen from another plant.
What is the pollination process of the flower?
Transfer of viable pollengrains fron anthers to the stigma is pollination.
Why is the stigma a different height than the anthers?
The stigma is typically positioned at a different height than the anthers to minimize the chances of self-pollination. By having the stigma situated higher or lower than the anthers, it reduces the likelihood of pollen from the same flower fertilizing the ovules, promoting outcrossing and genetic diversity. This separation helps increase the chances of pollination by pollen from a different plant, enhancing genetic variability in the species.
Where is the flower's pollination stored before pollination?
Before pollination, the pollen grains are stored in the anthers (male part) of the plant. During pollination, an insect (such as a bee) flies to the flower for nectar and some pollen from the anthers rubs off on it. When the bee travels to another flower, the pollen sticks to the stigma (female part). After pollination, fertilization can begin. Hope this helps.
What is the difference between self-pollenation and cross-pollenation?
self pollination means transfer of pollen from the anthers to the stigma of the same flower. Cross pollination means transfer of pollen from the anthers of one flower to the stigma of another flower.
How might having the anther atop a tall filament make it more likely plants will be pollinated?
Having the anther atop a tall filament increases the chances of pollen being carried away by wind or by pollinators such as bees or butterflies. This positioning also reduces the likelihood of self-pollination and promotes cross-pollination, increasing genetic diversity within the plant population.
Why does the anthers hang outside the flower?
Anthers are placed outside the flower to enhance the process of pollination. When an insect or bird lands on the flower to collect nectar, they come in contact with the anthers and inadvertently transfer pollen to other flowers as they move around, facilitating cross-pollination. This design increases the chances of successful reproduction for the plant.
Why did mendel remove the anthers from the pea plants when performing cross-pollination in his experiment?
Mendel removed the anthers from the pea plants to prevent self-pollination, as he wanted to control the pollen used for cross-pollination. By removing the anthers, he could ensure that only the desired pollen was used to fertilize the pistil of the plant. This allowed Mendel to accurately study the inheritance patterns of specific traits in his experiments.
