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 combination of material from a pollen grain with an egg to form a seed?
When pollen grains land on the stigma of a flower, a pollen tube grows to deliver the male gametes to the ovule. The male gametes fuse with the female gametes in the ovule to form a zygote, which develops into a seed after fertilization. The seed contains genetic material from both the pollen grain (male) and the egg (female).
In conifers such as pines sperm contained in pollen grains are primarily transferred to an egg by what?
In conifers, such as pines, sperm contained in pollen grains are primarily transferred to an egg by wind pollination. This process involves the dispersion of pollen from male cones to female cones through the air. Once the pollen reaches the female cone, it fertilizes the egg to form a seed.
How the nucleus form a pollen grain fertilize a female egg cell?
During pollination, the male nucleus in a pollen grain is transferred to the female egg cell within the ovule of a plant. This transfer is facilitated by a pollen tube that grows from the pollen grain to the ovule. Once the pollen tube reaches the egg cell, the male nucleus fuses with the female nucleus to form a zygote, which eventually develops into a new plant embryo.
How close to the egg can the pollen grain get?
when a pollen grain lands on the stigma it creates a pollen tube that goes down to the egg where sperm fuzes with the egg.

What is the correct order of pollen traveling through a flower?
Once the flower is pollinated the pollen travels down the pistil until it reaches the female cell, the egg cell. When the pollen and egg cell join they form a seed.
How the nucleus form a pollen grain fertilizers a female egg cell?
by raping it
What happens when a egg and sperm unite?
The sperm unites with the Ovum in the womb, to form a zygote, which is the beginning of the Embryo.

What is flower fertililzation?
Flower fertilization is when the pollen gets into the female parts of the flower and the seeds start to form. Each ovule or egg needs some pollen to form a seed.
How the nucleus form a pollen grain fertilize a female egg cell?
During pollination, the male nucleus in a pollen grain is transferred to the female egg cell within the ovule of a plant. This transfer is facilitated by a pollen tube that grows from the pollen grain to the ovule.

when a pollen grain lands on the stigma it creates a pollen tube that goes down to the egg where sperm fuzes with the egg.
How is fertilization in flowering plants different from fertilization in any other living organism?
Fertilization in flowering plants is achieved through pollen tube in which the non -motile male gametes travel to reach the egg and the secondary nucleus. Thus, in flowering plants there is double fertilization i. e. one male gamete unites with the egg to form the zygote which develops in to an embryo and the other male gamete present inthe same pollen tube unites with two polar nuclei (or their fusion product, known as secondary nucleus) to form the endosperm, which nourishes the developing embryo. In other organisms the male gametes are generally motile and double fertilization does not take place.
Does a egg if a plant pass through the pollen tube or something different?
An egg in a plant does not pass through a pollen tube. In plant reproduction, the egg cell is located in the ovule within the ovary of the flower. The pollen tube allows the sperm cells to travel from the pollen to the egg for fertilization to occur.
What unites during fertilization?
During fertilization the sperm unites with the egg. This typically occurs in the fallopian tube.
