2n because when 2 gametes of n amount of DNA fertilise together they make an organism that is similar to its parents and have the total amount of DNA as 2n, just like parents.
Binary fission is the process of a bacterial cell going from singular to double. Therefore the correct answer would be: "During binary fission, a bacteria cell grows in size because DNA and other organelles are duplicated."
Answer: For flowering plants, fertilization occurs through a process known as double fertilization. Unlike most plants, double fertilization enables the new seed to grow into a new plant and have a food source to begin growing. Double fertilization occurs within the female part of a plant, the pistol.
explanation: When pollen is formed by the anther, or male part of a plant, it will blow in the wind or attach to an organism that carries it to the top of the pistol, known as the stigma. Once the pollen attaches to the stigma, the pollen germinates and forms a pollen tube that extends into the ovary. Once formed, two sperm cells will be released and fertilize both the egg and the two polar nuclei of the plant to form the zygote and endosperm, respectfully.
