What is triple fusionDescribe the process of fertilization in an angiosperm plant what changes occur in the ovule after fertilization?
Triple fusion is a process in angiosperm fertilization where one sperm cell fuses with two polar nuclei in the embryo sac to form the triploid endosperm, which nourishes the developing embryo. During fertilization, a pollen grain lands on the stigma, germinates, and forms a pollen tube that delivers two sperm cells to the ovule. One sperm fertilizes the egg cell to create a diploid zygote, while the other sperm engages in triple fusion. After fertilization, the ovule transforms into a seed, and the surrounding ovary develops into a fruit, while the fertilized egg develops into an embryo and the endosperm nourishes it.

What happens first mitotic cell division in a testis or the process of fertilization?
the cell changes
What is the function of angiosperm flowers?
The flowers of the angiosperm are reproductive organsoften containing both male and female reproductive parts.
What process occurs after fertilization that changes a cell from single diploid to thousands of cells?
Lots and lots of cell division.
What process characterizes a sexual reproduction?
Fertilization
What changes will take place in the petals and the ovary after fertilization has occurred?
After fertilization, the petals of the flower will often wither and drop off, as they are no longer needed for attracting pollinators. The ovary will begin to develop into a fruit, which will house the seeds that result from the fertilization process.

What process in angiosperm produces a diploid zygote and a triploid endosperm?
Double fertilization in angiosperms produces a diploid zygote and a triploid endosperm. This process involves one sperm cell fertilizing the egg cell to form the zygote, while another sperm cell fuses with the central cell to form the endosperm.

As the seeds of an angiosperm develop the ovary change into a?
As the seeds of an angiosperm develop, the ovary changes into a fruit. The ovary wall thickens and matures into the protective and often edible structure that surrounds and protects the seeds. This process helps with seed dispersal and ensures the plant's reproductive success.
What kind of fertilization do sponges use in their reproductive process?
Sponges use internal fertilization in their reproductive process.
What process by which the egg cell and sperm cell unite during sexual reproduction?
No. Fertilization is the joining of an egg and sperm.
Which term refers to the process in which two gametes fuse to make one zygote?
fertilization
Process of uniting an egg with a sperm?
The process of uniting an egg with a sperm is called fertilization. It occurs when a sperm cell penetrates the outer layer of an egg cell and fuses with the egg's nucleus, forming a zygote. This marks the beginning of a new organism's development.
What is the Process during which a spermatid is converted to motile spem?
The process by which a spermatid is converted into a motile sperm is called spermiogenesis. During spermiogenesis, structural changes occur that lead to the development of the tail and the formation of the acrosome, which is necessary for sperm motility and fertilization. This process involves extensive modifications to the spermatid's shape and organelles to enable it to swim and penetrate the egg for fertilization.
