Ferns do not produce pollen; instead, they reproduce via spores. When spores land on a suitable environment, they can germinate and develop into a gametophyte, which eventually leads to the formation of new fern plants. If pollen from seed plants accidentally lands on a fern, it has no effect, as ferns and seed plants reproduce through entirely different mechanisms. Ferns rely on water for fertilization, specifically for sperm to swim to the egg cell, while pollen is a feature of seed-producing plants.
No, ferns do not have pollen. They reproduce with spores.
Yes they do. Most commonly called spoaring. They spread spoares in the air.
Yes, if a tree stays green all year round then it is an evergreen.
No, pollen allergies do not directly cause a fever. Fever is typically a response to an infection or illness, not an allergic reaction to pollen.
Pollen can make people with hayfever sneeze and suffer from watery eyes. This is an allergic reaction.
Yes, the reaction distances increases with speed while reaction time stays the same. for example the two-second rule.
In a chemical reaction, the total mass of the substances involved stays constant. This is known as the law of conservation of mass.
Yes, pollen allergies can cause fever in some individuals as a part of their allergic reaction.
Pollen
Most fern has seed, but a very little produce fruit.
Yes, seedless plants produce pollen. Pollen is the male reproductive structure responsible for transferring sperm cells to female reproductive structures in plants for fertilization. Seedless plants, such as ferns and mosses, rely on spores for reproduction, but they still produce pollen for this purpose.
They don't, nothing happens. Why someone would get an allegeric reaction is for this reason. Your "disease fighters" (white blood cells) mistakes the pollen for a disease and attacks it by letting antibodies out. What the allergic reaction is, is basically an over reaction of your body fighting the substance.
