Birch pollen is the fine, powdery substance produced by birch trees during their reproductive cycle, typically in spring. It contains male gametes and is dispersed by the wind to fertilize female flowers, facilitating seed production. Birch pollen is a common allergen, causing seasonal allergic rhinitis, or hay fever, in many individuals due to its high allergenic potential. Its presence in the environment can trigger allergic reactions in sensitive people, leading to symptoms like sneezing, runny nose, and itchy eyes.

No, birch trees are not poisonous to humans. The sap, leaves, and bark of birch trees have been used in traditional medicine and culinary purposes. However, some individuals may have allergic reactions to birch pollen.
Grapes primarily produce pollen from the Vitis genus, which includes various species of grapevines. The pollen is typically wind-pollinated and is not a major allergen compared to other plants, such as ragweed or birch. The pollen grain itself is small and can be found in the air during the flowering season of grapevines, which usually occurs in late spring to early summer. However, most grape varieties are self-pollinating, which means they often do not require pollen from other grapevines for fertilization.
The pollen for each kind of tree or flower is distinctive to that species, so there is no definite description for what pollen in general looks like - the grains aren't even all round; the size also varies: for instance, a grain of pollen from an elm tree (which is round) is about 20 micrometers in diameter, whereas a pollen grain from a Scots pine tree is kinda kidney shaped, & measures about 40 x 60 micrometers
Birch bark is not a living organism, however the birch tree, where birch bark comes from, is.
