What is difference between ungerminated pollen grain and germinated pollen grain?
The germinated pollen grain is empty of the male gamete nucleus.
What makes seeds when combined with a flower's eggs?
This tiny grain is called pollen grain.
How does pollen grain compare to a microspore?
microspore when develops a exine around it, is called a pollen grain.
Is a pollen grain spore?
Yes of course, it is a microspore which becomes a pollen grain after developing an exine
How close to the egg can the pollen grain get?
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.
Do Dicot have pollen grain?
yes Dicot have pollen grain and in Dicots pollen grain possess 3 germ pores
What is difference between ungerminated pollen grain and germinated pollen grain?
The germinated pollen grain is empty of the male gamete nucleus.
What makes seeds when combined with a flower's eggs?
This tiny grain is called pollen grain.
Can a pollen grain of a flower have one lobe?
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.
How does pollen grain compare to a microspore?
microspore when develops a exine around it, is called a pollen grain.
Is a pollen grain spore?
Yes of course, it is a microspore which becomes a pollen grain after developing an exine
How does a pollen grain travel through the parts of a flower to finally become a seed?
The pollen grain released from the anther lobe during anthesis reaches the stigma by pollination. Thereafter, it germinates on the compatible stigma to send pollen tube to the micropyle of the ovule inside the ovary. The male gametes from the pollen grain are transferred to the embryo sac for fertilization and the ovule is converted into a seed when zygote develops into an embryo.
Why used the mature pollen grain in pollen germination experiment?
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
How close to the egg can the pollen grain get?
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.
What structure will pass down the pollen tube?
the pollen grain
What produces pollen grains?
The anther produces pollen grain.
A pollen grain produce a narrow tube called?
The pollen grain produces a narrow tube called the corbicula.
