What happens between pollination and fertilisation?
After pollination, the pollen grain germinates and forms a pollen tube that grows down the style of the pistil to reach the ovule. Fertilisation occurs when the sperm cell from the pollen grain fuses with the egg cell in the ovule, resulting in the formation of a zygote.
What is the name given to the structure in the flower in which the sperm cell is formed?
The structure in the flower where sperm cells are formed is called the anther. It is part of the male reproductive organs of the flower and is responsible for producing pollen grains containing the sperm cells.
In seed plants the sperm make it to the egg via?
By swimming in watery fluid through the neck of archegonium the sperm reaches to the egg in seedless plants.
Where are a plants sperm cells located before fertilization occurs?
When a pollen grain is immature male gametophyte, it has two cells ,a generative cell and a tube cell. A pollen grain becomes a mature male gametophyte when the generative cell divides by mitosis to form two sperm cells. In most species, this process occures after the pollen grain lands on the stigma of a carpel and the pollen tube begins to form. $$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$
What is one entire male gametophyte of a gymnosperm?
The male gametophyte of a gymnosperm is a pollen grain, which consists of two cells: a generative cell that will divide to form two sperm cells, and a tube cell that aids in the pollen tube formation.
What is the tube that grows out of a pollen grain contains?
The tube that grows out of a pollen grain contains two sperm cells. These sperm cells are needed for fertilization in plants, where one sperm cell fuses with the egg cell to form a zygote, while the other fuses with the central cell to form the endosperm.

In a grain of pollen what is the function of the sperm that doesn't join with the egg cell?
In a grain of pollen,what is the function of the sperm cell that doesn't join with the egg cell?
What is the pollen grain that sends tube down pistil and unites with the ovule?
The pollen grain that sends a tube down the pistil and unites with the ovule is called a sperm cell. This process is known as fertilization and it leads to the formation of a seed. The sperm cell from the pollen grain fertilizes the egg cell within the ovule, initiating seed development.
What is the male sex cell from a pollen grain called?
The male sex cell from a pollen grain is called a sperm cell. It is responsible for fertilizing the female sex cell (ovule) in plants during the process of pollination.
In seed plants the sperm make it to the egg via?
By swimming in watery fluid through the neck of archegonium the sperm reaches to the egg in seedless plants.
What travels down the pollen tube and fertilizes?
The pollen tube carries the male gametes (sperm) from the pollen grain to the egg cell in the ovule. Once the pollen tube reaches the ovule, the sperm fertilizes the egg cell, resulting in the formation of a seed.
What grows down from the pollen grain after pollination?
A pollen tube emerges out from the pollen grain fallen on the stigma which leads the male sex cell to the ovary through style (a connection stigma & ovary.
What happens when two pollen grains land on the same stigma and after the first grain fertilises the ovule?
When a pollen grain lands on stigma, pollination occurs. The pollen grain germinates and the pollen tube grows through the style. The sperm nucleus travels through the tube (generated by the tube nucleus) and fuses with an ovule which then develops into an embryo (or zygote)
When the pollen grain germinates on the stigma what burrow is it called?
When a pollen grain germinates on the stigma, it forms a structure called the pollen tube. This tube grows down through the style towards the ovary, allowing sperm cells to travel to the ovule for fertilization. The successful formation of the pollen tube is crucial for the fertilization of the egg cell and subsequent seed development.
