The tube nucleus is a specialized structure found in the pollen grain of flowering plants. Its primary function is to guide the growth of the pollen tube during fertilization. Once the pollen grain lands on a compatible stigma, the tube nucleus directs the formation of the pollen tube, allowing sperm cells to travel to the ovule for fertilization. This process is crucial for the successful reproduction of flowering plants.

What is the function of the nucleus within a cell that is responsible for the transportation of materials through the tube-like structures?
The nucleus in a cell is responsible for controlling the cell's activities and contains genetic material. It does not directly transport materials through tube-like structures. That function is carried out by the endoplasmic reticulum, a network of membranes within the cell.
What is the fate of the tube nucleus in the pollen tube?
The tube nucleus in the pollen tube typically disintegrates as it moves downwards in the pollen tube to ensure that the sperm cells reach the ovule without interference. This allows for successful fertilization to occur by facilitating the fusion of the sperm cells with the egg cell and central cell in the ovule.
How do the sperms nuclei in a pollen grain reach the egg nucleus in an ovule?
When they land on the style they begin to bore their way through the stigma all the way to the ovule. Through the tube made by the tube nucleus of the pollen grain: each pollen grain has two nuclei, one called generative nucleus which combines with the nuclei of the ovule, and the other called tube nucleus tube nucleus which forms a tube that penetrates the stigma till it reaches ovule then it degenerates.
