There are 50 chromosomes in both male and female pineapple pollen grain.
There are 50 chromosomes in a pineapple. Isnt that alot?
There are 50 chromosomes in a female nucleus of a pineapple pollen grain.

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').
Tube nucleus generates after guiding the pollen tube into the embryo sac
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.
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

they can by having sex with bugs on the pollen the flower is then able to unlese the power of its self
Half of the individual cell of ovule except female gametophyte cells
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
The pollen tube nucleus directs the growth of the pollen tube down through the pistil to the ovary
Yes, pollen grains have a nucleus. The nucleus contains the genetic information necessary for the pollen to fertilize a plant's ovule.
