Pollen tube growth is one of the most fascinating—and essential—phenomena in the life cycle of flowering plants. After a compatible interaction between pollen grains and the stigma surface, the pollen germinates and forms the pollen tube, which grows through the stigma, style, and transmitting tract to deliver the sperm cells to the ovule."
2) Although pollens of many species germinate in simple aqueous media, stigmas do not provide satisfactory sites for the germination of most foreign pollen... Stigmas not only provide the proper conditions for the germination of pollen from their particular species, they actively inhibit the germination of pollen of many unrelated species.
The highlighted vessels branch into arcuate arteries.
Arcuate arteries- The interlobar arteries bend over to produce imperfect arches at the point where the cortex and medulla meet. The arcuate artery is the name given to this portion of the blood supply as a result. The arcuate artery divides into several tiny radial arteries, which diverge at right angles and provide blood to the cortex.
Vessels- In the blood, vessels (canals) move waste away from organs and tissues and carry nutrients to those tissues. The vasculature's participation in oxygenating the organism serves as one of its main functions and important roles.
