In wind-pollinated flowers, protruding and easily movable anthers enhance pollination by maximizing exposure to the airflow. Their positioning allows the wind to effectively dislodge pollen, promoting its dispersal over greater distances. Additionally, the flexibility of these anthers ensures that they can release pollen efficiently, increasing the chances of it reaching other flowers. This adaptation is crucial for successful fertilization in environments where animal pollinators are absent.
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.
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.
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.
pollen grains are produced in pollen sac of anthers which are present on the male gamets of flower
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.

remove the anthers or stigmas of the two plants to prevent accidental or self-pollination after you have hand pollinated them
yes
In rice plants, it is the flower that is being pollinated. The rice flower contains both male and female reproductive structures, allowing for self-pollination or cross-pollination. The pollen from the anthers (male parts) is transferred to the stigma (female part) of the same or another flower, leading to fertilization and the development of rice grains.
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.
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.
Transfer of viable pollengrains fron anthers to the stigma is pollination.
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.
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.
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.
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.
