What are characteristics of water pollination in Vallisneria?
Water pollination in Vallisneria includes the release of male flowers that float to the surface, where they release pollen. The pollen is then carried by water currents to reach the female flowers, which are anchored underwater. This method allows for effective pollination in submerged aquatic environments.
Does the wind often carry pollen from male cones to female cones in gymnosperms?
Yes, wind is a common method for pollen dispersal in gymnosperms. Male cones produce pollen grains that are lightweight and easily carried by the wind to female cones where they can fertilize the ovules. This wind-mediated pollination allows gymnosperms to reproduce without the need for animals or water.
What happens to the pollen when it goes into the air?
Pollen can easily become airborne and when it does, it can be carried long distances. it will settle on plants and other flowers to help pollinate or it can get into homes and on cars, and if you are allergic to a particular pollen you may develop hay fever symptoms when you breathe it in.
Why does a male gamete of a flowing plant have no cell wall?
The male gamete of a flowering plant, also known as a pollen grain, lacks a cell wall to facilitate its movement and fertilization. The absence of a cell wall allows the pollen grain to be carried by air or insects more easily to reach the female reproductive structures for fertilization.
Characteristics of insect wind and water pollinated flowers?
Insect-pollinated flowers are often brightly colored, have nectar guides or fragrances to attract insects, and have sticky pollen grains that adhere to insects for transfer. Water-pollinated flowers are often dull in color, lack nectar or fragrance, and produce large quantities of light, buoyant pollen grains that can be carried through water currents for dispersal. Additionally, water-pollinated flowers tend to have feathery stigmas that can easily capture pollen carried by water.
Pine pollen is primarily disseminated by?
Pine pollen is primarily disseminated by wind. The lightweight nature of pine pollen allows it to be easily carried by the wind over long distances to reach female pine cones for fertilization.

How is pollen transfered from the stamen to the pistil?
Some pollen is carried on the wind, other pollen is carried by insects such as bees. Some is from animals too. MAYBE YOU............
How are spores and pollen suited for dispersal?
Spores and pollen are very light in weight and are always being scattered by the air easily on the land and here they come in contact with the other dipersal agents and carried away from one place to another place.

What is the advantage of smooth and light pollen?
Smooth and light pollen can be easily dispersed by wind or carried by pollinators, increasing the chances of successful pollination. These types of pollen are also less likely to clump together, allowing for more uniform coverage on the stigma of the flower.

What are the special features of a pollen cell?
Pollen cells are specialized reproductive cells produced by plants for pollination. They are small and lightweight, making them easily carried by wind or pollinators. Pollen cells contain male gametes that are necessary for fertilization when they reach a compatible female structure on another plant.
Why is pollen light weighted?
Pollen is lightweight so it can be easily carried by the wind or animals to fertilize other plants. Its light weight enables it to travel long distances and increase the chances of pollination occurring.
Why do gymnosperms do not need water for fertilization?
Gymnosperms do not need water for fertilization because their male gametes are carried by pollen grains, which can be transported by the wind. This allows for fertilization to occur without the need for water.
