WebThe female gamete is produced inside the embryo sac of the ovule. In angiosperms the division of a generative cell into two sperm nuclei, resulting in the production male gametes (always two), which develop inside the pollen grain (in 30% of species) or the pollen tube (in 70% of species), respectively,) of the plant. In short a gamete is an egg cell (female gamete) or a sperm (male gamete). In animals, ova mature in the ovaries of females and sperm develop in the testes of males. During fertilization, a spermatozoon and ovum unite to form a new diploid organism. [2] Gametes carry half the genetic information of an … See more A gamete is a haploid cell that fuses with another haploid cell during fertilization in organisms that reproduce sexually. Gametes are an organism's reproductive cells, also referred to as sex cells. In species that … See more In contrast to a gamete, a diploid somatic cell of an individual contains one copy of the chromosome set from the sperm and one copy of the … See more Artificial gametes, also known as In vitro derived gametes (IVD), stem cell-derived gametes (SCDGs), and In vitro generated gametes (IVG), are … See more • Coenogamete See more It is generally accepted that isogamy is the ancestral state from which anisogamy evolved, although its evolution has left no fossil records. Oogamy also evolved from isogamy through … See more Humans and most mammals use the XY sex-determination system in which a normal ovum can carry only an X chromosome whereas a sperm may carry either an X or a Y, … See more Plants which reproduce sexually also produce gametes. However, since plants have a life cycle involving alternation of diploid and haploid generations some differences exist. Plants use meiosis to produce spores that develop into multicellular See more

What is the female gamete of a plant? - Answers
WebThe female gametes, or eggs, are formed in the ovules, within the flower. Here, as above, a certain diploid cell undergoes meiosis; however, in this case the result is four haploid megaspores —"large spores"). Three of … WebMale gametes reach female gametophyte and the egg cell gamete though a pollen tube: an extension of a cell within the pollen grain. The sperm of modern gymnosperms lack flagella, but in cycads and the Gingko , the sperm still possess flagella that allow them to swim down the pollen tube to the female gamete; however, they are enclosed in a ... Web48 chromosomes (24 from each parent, including one sex chromosome from each) Review: All somatic cells in animals have two sets of chromosomes, one haploid set (n) from each parent, and each set includes one sex chromosome. For an animal with a diploid number of 48 (2n = 48), the number of chromosomes in the somatic cells is 48 and the number of … enthralled defined
