because then the embryos would be fertilized by the sperm, and 1. men would have babies. or 2. women would have two babies every time conception takes place
Female gametes fused with male gametes make a zygote, which is a fertilized egg with a full set of chromosomes. This zygote then develops into an embryo and eventually a new individual through the process of cell division and differentiation.
The male gamete - spermatozoon and the female gamete - ovum.
In Angiosperms the pollen tube pierces the wall of the embryo sac and releases two male gametes. One of these male gametes fuses with the egg to form the zygote and the other to the secondary nucleus to form the endosperm. the developing embryo is nourished by the endosperm. A fully developed embryo remains in the ovule and the latter is converted in to the seed. In gymnosperms the female gametophyte nourishes the develoing embryo instead of endosperm and the embryo develops from the zygote inside the archegonium instead of embryo sac.
it doesnt. male papaya trees only produces flowers
the pollen grains after landing on the stigma germinate to send out pollen tubes through which the male gametes reach near the egg cell of embryo sac in the ovule to fuse with. this fusion of male and female gametes (egg cell) is called fertilization.
The fertilized egg becomes an embryo and later becomes a fetus.
The Male Gametes are formed in the testicles.
reproduction are of 2 types sexual reproduction which involves gametes male gametes:-- sperms female gametes:-- ovum these 2 gametes need to be fused together to form an embryo then through mitosis it will divide millions of time to make a baby in plants male gametes:-- pollen grain female gametes:-- ovary in these when pollen gets in another flower due to pollination it forms an pollen tube through the style and fuses with the ovary and forms seeds!! in short the gametes are responsible for reproduction in sexual reproduction
In plants, female gametes are found within the ovules, which are located inside the ovaries of the flowers. The ovules develop into seeds after fertilization, and the female gametes, known as egg cells, are produced in the embryo sac within the ovule. During pollination, pollen grains carry male gametes to the ovule for fertilization.
2 male gametes
Pollination ensures the availability of male gametes for fertilization to form zygote for embryo development inside the ovule, that later on becomes a seed.
In asexual reproduction of a plant, the plant reproduces offspring (normally referred to as daughter cell) in and of itself, without the the use of male and female gametes of the plants. There is no swapping or joining of gametes. Sexual reproduction uses the male and female gametes (both haploid), such as pollen from the male plant's stamen joining the ovule in the female plant's pistil - resulting in a diploid embryo.
