pollen grains are the powdery pollens in the pollen sacs . Pollen sacs are situated in the anther. For a pistil to develop into a fruit and ovules to mature into seeds, pollen grains must be transfered from anthers to the stigma. This process is called pollination.
yes Dicot have pollen grain and in Dicots pollen grain possess 3 germ pores
The germinated pollen grain is empty of the male gamete nucleus.
This tiny grain is called pollen grain.
No, after a research it is not seen that a pollen grain of a flower have only one lobe. Commonly pollen grain have two or three lobes.
A pollen grain is a mature microspore that consists of two cells (generative cell and tube cell) enclosed within a protective wall. A microspore is a haploid cell produced in the sporangia of seed plants that eventually develops into a pollen grain through the process of microsporogenesis.
Yes of course, it is a microspore which becomes a pollen grain after developing an exine
this is because premature pollen grain do not contain the sperm cell for fertilization. only the generative nucleus in mature pollen grain will divide mitosisly to form sperm cell for fertilization
when a pollen grain lands on the stigma it creates a pollen tube that goes down to the egg where sperm fuzes with the egg.
the pollen grain
The anther produces pollen grain.
The pollen grain produces a narrow tube called the corbicula.
no the pollen grain contains the male genetic material - sperm cells
