Flowers
Sunflowers usually produce the most pollen. More than other flowers.
Flowers produce so much pollen to increase the chances of one grain managing to fertilise.
the bees that get the pollen produce it all back but not all they take and thats how flowers die
pollen grain
No female plants that are stressed will turn into hermaphrodites and produce flowers with pollen as well as female flowers
Bees don't produce pollen, they collect it from flowers.
In flowers, the anthers produce pollen.
I'll say no. There are flowers that are called "perfect" which produce both pollen and ovules (seeds). There are flowers that only produce pollen. There are flowers that only produce ovules. There are sometimes flowers that don't produce pollen or ovules, but help attract pollinators to the flowers next to them (like asters). There are even some flowers that produce both pollen and ovules, but the seeds that they produce are produced without sex (it's called apomixis and is pretty rare).
Flowers, trees and shrubs that produce pollen and/or nectar.
Flowers release pollen in the spring and early summer because these are the times when the conditions are just right to produce life from the pollen, as there is more heat than in the autumn/winter.
