Viroids, they are they are passed through pollen.
The pollen tube grows out of or through the pollen grain.
how pollen tube grows down through the style
Pollen travels through the plants ovaries up to the stamen waiting for a bee to release pollen around.***
Shogun disease/SLE?
Pollen travels through the air by a wind blowing the pollen and landing on soil and re growing this is called pollenation
Some people may be allergic to flower pollen but it does not cause any diseases. Disease are generally caused by bacteria or viruses.
Sucrose acts as a source of energy for the growing pollen tube, providing the necessary fuel for its elongation. Water is crucial for maintaining turgor pressure within the pollen tube, which helps it to push through the pistil tissues during growth. Both substances play essential roles in the formation and elongation of pollen tubes.
Allergies from hay fever can have a number of different environmental causes. Hay fever can result as an allergic reaction to tree pollen, grass pollen, spores, fungi, and mold.

The pollen tube nucleus directs the growth of the pollen tube down through the pistil to the ovary

An egg in a plant does not pass through a pollen tube. In plant reproduction, the egg cell is located in the ovule within the ovary of the flower. The pollen tube allows the sperm cells to travel from the pollen to the egg for fertilization to occur.
