human reproduction

• Implantation is the process in which the zygote attaches to the uterine wall.
• Testesterone is the male hormone
• asexual reproduction is when one parent produces offspring with the same genes as itself
• sexual reproduction is the fusion of male and female gametes to form a zygote
• the sex cells contains half the body chromosomes
• the body cells consists of 46 chromosomes
• meiosis is the process of cell division that produces four haploid gametes
• mitosis is the process of cell division that results in two identical daughter cells
• the zygote is the fertilized egg that develops into a fetus
• asexual cells devide ones
• asexual reproduction occurs through out lifetime of an organism
• asexual reproduction uses diploid cells
• Large organisms uses mitosis for growth and repair.
• mieosis cells devides twice
• meiosis reproduction occurs during sexual reproduction
• meiosis uses haploid cells to produce gametes
• meiosis uses the same chromosomes as mitosis, but the chromosomes are not identical
• meiosis uses gametes to produce haploid gametes that are genetically different from each other
• Plants also produce sexually
• fertilisation is where the sperm cell fuses with the egg cell
• Asexual reproduction does not requires special cells
• asexual reproduction produces offspring that are clones of their parent
