The difference between protons and neutrons are that one has a positive charge and one has a neutral charge. The similarities between the two is that they both make up an atom. The Electrons in an atom are in orbit of the cell inside the Electron cloud and is kept in the cloud by electromagnetic force.
Answer:
Zygote
Explanation:
As a result of meiosis in the male and female sex organs of a plant, male and female gametes or male and female sex cells produced respectively. Gametes are universally haploid. Male and female gametes fuse or fertilize to form a diploid zygote. A zygote or fertilised egg is a one-celled structure which later develops into an embryo.
Answer:
True
Explanation:
Meiosis is the kind of cell division that results in the production of daughter cells with each cell having half number of chromosomes as the parent cell. Meiosis is the cell division employed by reproductive cells to produce gametes/sex cells. Meiosis occurs in two stages i.e. Meiosis I and II. The chromosome number reduces by half in gametes in order to ensure that after fertilization of both male and female gamete, the resulting organism has the correct set of chromosomes. e.g diploid organism produces haploid gametes which fuses to produce a diploid organism again.
Mitosis is another type of cell division that results in identical daughter cells. They are identical in the sense that they possess the same number of chromosomes as the parent cell that divided. For example, a diploid cell undergoes mitosis to produce two diploid daughter cells.
