The pollen for each kind of tree or flower is distinctive to that species, so there is no definite description for what pollen in general looks like - the grains aren't even all round; the size also varies: for instance, a grain of pollen from an elm tree (which is round) is about 20 micrometers in diameter, whereas a pollen grain from a Scots pine tree is kinda kidney shaped, & measures about 40 x 60 micrometers
A single pollen grain looks like a fine coarse powder that contains the microgametophytes of seed plants. These microgametophytes produce the male gametes.
Pollen comes in as many shapes as sizes as plants do. Most are spherical, and contain specific markings characteristic of that species.
Kind of spongy looking . Brown and orange kind of color

In a grain of pollen,what is the function of the sperm cell that doesn't join with the egg cell?
the transfer of the male pollen grain to the female organ.
There are two things that must join to make a seed. The zygote, or embryo, must join with the ovule.
The wind aids in pollination when plants transfer pollen grains. Insects can also help in the transferring of pollen grains.
He observed the same movement. When the experiment was repeated with rock dust the same movement was observed.
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.
microspore when develops a exine around it, is called a pollen grain.
Yes of course, it is a microspore which becomes a pollen grain after developing an exine
its like the sperm of plants
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 anther produces pollen grain.
the pollen grain
The pollen grain produces a narrow tube called the corbicula.
