Fertilization in flowering plants begins with pollination, where pollen grains from the male anther are transferred to the female stigma. The pollen grain germinates, forming a pollen tube that grows down the style toward the ovary, where ovules are located. The tube penetrates the ovule, allowing the sperm cells to travel down and fertilize the egg cell, resulting in a zygote. Simultaneously, one sperm fuses with two polar nuclei to form triploid endosperm, which nourishes the developing embryo, completing the fertilization process.
What else can I help you with?
What are flowering sperms?
There is no such thing as "flowering sperms." Sperm are male sex cells that are involved in the process of fertilization in flowering plants. Flowering plants reproduce through the union of male and female sex cells contained within their flowers.
Which group of plants produce double fertilization?
Double fertilization occurs in angiosperms, which are flowering plants. It involves the fertilization of both the egg cell and the central cell in the ovule to form the embryo and endosperm, respectively. This process is unique to angiosperms and plays a crucial role in seed development.
What group of plants practices double fertilization?
Angiosperms, or flowering plants, are the group of plants that practice double fertilization. In this process, one sperm fertilizes the egg to form the embryo, while the other sperm fuses with the central cell to form the endosperm, which provides nutrients to the developing embryo.
What is the process of fertilization in flowering plants where new seeds are formed called?
The process of fertilization in flowering plants where new seeds are formed is called pollination. During pollination, pollen grains are transferred from the male reproductive organ (anther) to the female reproductive organ (stigma) of the flower, leading to fertilization and seed formation.
Do ferns undergo double fertilization?
No, ferns do not undergo double fertilization. Double fertilization is a process characteristic of flowering plants (angiosperms), where one sperm fertilizes the egg and the other fuses with two polar nuclei to form the triploid endosperm. In ferns, fertilization involves the fusion of a single sperm with an egg, leading to the formation of a zygote, but does not involve the additional fertilization event seen in angiosperms.

What kind of spores are produced by flowering plants?
Flowering plants produce pollen grains, which are equivalent to spores in non-flowering plants. These pollen grains are responsible for plant reproduction through the process of pollination, where they are transferred to the female reproductive organs of the flower for fertilization.
What process characterizes a sexual reproduction?
Fertilization
What becomes integuments after fertilization?
After fertilization, the integuments of the ovule develop into the seed coat. The seed coat serves to protect the developing embryo and the stored nutrients within the seed. In flowering plants, this transformation is part of the seed development process, which ensures the survival and dissemination of the plant species.
What is the function of tube nucleus?
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 do the pollen and the egg become fertilization?
During fertilization, pollen, which contains male gametes, fertilizes the female gamete within an ovule (the egg). This union results in the formation of a zygote, which will develop into a seed. The process is essential for sexual reproduction in flowering plants, leading to the creation of new offspring.
Does double fertilization occur in the Division Anthophyta?
Yes, double fertilization occurs in Division Anthophyta (flowering plants). It involves the fusion of one sperm cell with the egg to form a zygote and another sperm cell with the polar nuclei to form endosperm. This unique process is a key characteristic of flowering plants.
What are the events leading to fertilization in flowering plants?
Fertilization in flowering plants involves the transfer of pollen from the anther to the stigma, followed by the growth of a pollen tube to deliver sperm cells to the ovule. Upon reaching the ovule, one sperm cell fertilizes the egg cell to form a zygote, while the other sperm cell fuses with the central cell to form endosperm. This process eventually leads to seed development.
