Reproduction - Coggle Diagram

- - - - Sperm- male reproductive cells; the product of meiosis
        
        A cell that is able to move itself
        
        Spermatogenesis- creation of sperm
      - Ovum/egg- female reproductive cells; the product of meiosis
        
        Often has a thick layer on the outside to make it challenging for a sperm to enter
        
        Oogenesis- creation of eggs
      - Haploid
  - - - Cell Cycle- a cell grows, prepares for division, and divides to form two daughter cells
        
        Anaphase
        
        the chromosomes separate and move to the opposite ends of the cell
        
        Telophase
        
        the distinct individual chromosomes begin to spread out into a tangle of chromatin
        
        Metaphase
        
        the chromosomes line up across the center of the cell
        
        Prophase
        
        chromosomes condense and become visible
        
        crossing over occurs (homologous chromosomes pair up in cell during fertilization)
        
        Homologous chromosomes- chromosomes in which one set comes from the male parent and one from the female parent
        
        Interphase (not a phase of the cycle)
        
        all the DNA is replicated
        
        period of the cell cycle between cell divisions
- - - - Cytokinesis- division of the cytoplasm (of an eukaryotic cell) to form two separate daughter cells
- - - - offspring will all be clones
        
        runner (made through mitosis) example: strawberry
  - - - anthers = male part
      - stigma = female part
- - - - Vas deferens
        
        tube that carries sperm from the epididymis to the urethra
      - Prostate gland
      - Epididymis
      - Urethra
        
        tube through which urine leaves the body
      - Testis
        
        primary male reproductive organ; produces sperm
      - Penis
    - - Sperm developed in the testis (also where testosterone is produced)
      - Sperm mature in the epididymis
      - During ejaculation, sperm travel into the vas deferens
      - Vas deferens bring sperm up to pass the seminal vesicle and prostate gland, where fluids are added
      - The fluid then leaves the body through the penis through the urethra
  - - - Fallopian tube
        
        tubes that stretch from the uterus to the ovaries
      - Ovary
        
        the primary female reproductive organ; produces eggs
      - Uterus
        
        Uterine lining- the inner layer of the uterus
      - Cervix
        
        the lower part of the uterus
      - Vagina
    - - if fertilization DOES NOT
        
        Egg leaves the body through the cervix and vagina
      - Fetus will go through the cervix then the vagina to be born
      - Egg travels along the fallopian tube to the uterus
      - Egg is released to the fallopian tube during ovulation
      - Egg matures in the ovary
      - if fertilization DOES happen
        
        Egg implants into the uterine lining for 9 months
    - - Embryo
        
        an early stage of development that occurs right after the fertilization
      - Fetus
        
        an unborn child that grows and develps inside the uterus
      - Zygote
        
        a fertilized egg
      - Fertilization
        
        process in sexual reproduction in which male and female reproductive cells join to form new cell
