What is the yellow powder sometimes left it rains?
Probably tree pollen. Many species of trees produce copious quantities of airborne pollen.
What is the range of pollen count?
Pollen count is the measurement of the number of grains of pollen in a cubic meter of air. The higher the number, the more people will suffer if they are allergic to a particular pollen. Usually, the counts are announced for specific plants such as grass, ash or olive. These are tailored to what is usually a common plant in the area being measured.
Can plants cause respiratory health hazards for humans?

In Gymnosperms Male cones usually occur on higher branches and farther from the trunk than the female cones Why would this be?
When pollen from the male cones is released it either falls to the ground by gravity or is dispersed by wind or light breezes. Having the male cone above the female ensures that some pollen will drop onto the female cone via gravity; if the female were above the male no pollen would be able to reach the cone - more a mechanism to ensure self pollination if cross pollination fails. By having the male cones at the our edge of the tree canopy it also improves the pollens chance of being lifted by wind and deposited on a nearby tree (for cross pollination)

What will happen if the bee transfers pollen from a rose to a flowering tree?
it will just store up the pollen with the other pollen The bee would probably leave some of the pollen from the first flower in the second flower to pollinate the seeds there, and would probably pick up some pollen from the second flower. That's how it works.
What pine tree structure is responsible for the production of the pollen?
The cone.
What two months are considered the peak of tornadoes?

What does birch tree pollen look like?
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
