The nucleus in each cell in the stem of a plant contains 32 chromosomes How many chromosomes are there in the nuclei of its pollen grains?
16
Does the pollen come from a male or female part of the flower?
The 'pistil' is a female part of a flower. However flowers usually have both male and female parts, it is unusual for a plant to be just male or female (although there are examples such as 'holly' and 'cannabis').
What is the fate of the tube nucleus in the pollen tube?
Tube nucleus generates after guiding the pollen tube into the embryo sac
What is the function of the sperm nucleus in plants?
the sperm nucleus is found in pollen grains and directs the growth of the pollen tube to the ovule in the ovary, it then degenerates
How many chromosomes in a pollen cell?
This is an impossible question to answer the way it is phrased. One needs to know what plant species is being discussed before the question can be answered. Each species will have a unique number of chromosomes and its pollen will have half as many as the parent species.
How many chromosomes are there in the male nucleus in a pineapple pollen grain?
There are 50 chromosomes in both male and female pineapple pollen grain.

How the nucleus form a pollen grain fertilize a female egg cell?
they can by having sex with bugs on the pollen the flower is then able to unlese the power of its self
What parts of flowers are diploid?
The ovule is enclosed within the ovary, and contains the female gamete which has the haploid. (number of chromosomes)
How many chromosomes would a pollen grain have to compare to an ovule?
Half of the individual cell of ovule except female gametophyte cells
What does a pollen grain and ovule each contain?
Pollen grains contain the male gametes required for sexual reproduction of a plant/ flower. These are haploid, and only contain half the full set of chromosomes; the other half is contributed by the female gamete (or ovule).A grain of pollen contains:a larger vegetative cell (also called the tube cell) inside of which is aa smaller germ cell (also called the generative cell).The pollen grain "germinates" on the stigma of the receptive flower and grows down the style, once it reaches the ovule the germ cell/ nucleus fuses with the nucleus of the ovule and an embryo is formed
How does the pollen tube nucleus function in fertilization?
The pollen tube nucleus directs the growth of the pollen tube down through the pistil to the ovary
Does pollen have a nucleus?
yes
