Pollen grain after meiosis in the microspore mother cell and has haploid set of chromosomes. A seed develops from ovule after fertilization, in which the number of chromosomes get doubled.
Pollen grain is unicellular, microscopic structure, a seed is multicellular macroscopic structure.
If a pollen grain lands near an ovule, it can lead to pollination, where the pollen grain forms a pollen tube that grows towards the ovule. Once the pollen tube reaches the ovule, fertilization can occur, resulting in the formation of a seed.
The combination of material from a pollen grain with an egg to form a seed is what bees carry from one plant to another, unknowingly. When the bee lands on a plant it picks up pollen and carries this to another plant.
No, a pollen grain is not a spore. A pollen grain is a male gametophyte produced by seed plants for the purpose of reproduction, while a spore is a reproductive cell that can develop into a new organism without the need for fusion with another cell.
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.
When a pollen grain joins with an ovum, fertilization occurs, resulting in the formation of a zygote. This zygote then develops into an embryo that eventually grows into a new plant or seed. This process is crucial for the reproduction of flowering plants.

There are two things that must join to make a seed. The zygote, or embryo, must join with the ovule.
The pollen grain released from the anther lobe during anthesis reaches the stigma by pollination. Thereafter, it germinates on the compatible stigma to send pollen tube to the micropyle of the ovule inside the ovary. The male gametes from the pollen grain are transferred to the embryo sac for fertilization and the ovule is converted into a seed when zygote develops into an embryo.

A pollen grain is a mature microspore that consists of two cells (generative cell and tube cell) enclosed within a protective wall. A microspore is a haploid cell produced in the sporangia of seed plants that eventually develops into a pollen grain through the process of microsporogenesis.
The sperm of seed plants form inside the pollen tube, a structure that develops from the pollen grain. The pollen tube grows towards the ovule to deliver the sperm cells for fertilization.

No, pollen does not contain a sporophyte. Pollen grains are the male gametophytes of seed plants, which produce sperm cells needed for fertilization. The sporophyte generation of seed plants is the dominant phase of the life cycle and produces the pollen.
