Human
- biological offspring of sexual reproduction created by internal fertilization
Sexual Reproduction
- 2 gametes (sperm and egg) meet and interact with each other in order to form an offspring.
Multicellular Organism - involves a number of cells
Gamete - the reproductive cells of an organism; responsible for the creation of offspring
Sperm - a cell, located in a male's body; a mature sperm cell unites with the ovum during sexual reproduction; responsible for creation of offspring
Spermatogenesis
Ovum/egg - a cell, located in a female's body; able to develop a new organism after the process of sexual reproduction
Ovogenesis
Fertilization
Internal Fertilization - inside an organism
Chicken
Flowers
External Fertilization - outside of organism
Vagina
Uterus - home of the developing fetus
Ovary - produces eggs and hormones
Fallopian tubes - the egg cells travel through them to the uterus
Zygote
Fetus
Diploid
Cervix - sperm travels through the cervix to fertilize the eggs
Uterine lining
Penis
Testis - male reproductive gland; produces sperm and testosterone
Urethra - transports the stored urine out of the body
Vas deferens - transports sperm to the ejaculatory ducts
Asexual Reproduction
- does not involve interaction between multiple gametes. The offspring is delivered by only one gamete.
Single-celled Organism - depends on a single cell in order to survive
Prokaryotic
Eukaryotic
Bacteria
Runner
Potato
Meiosis
- the process of division of a single cell; each cell contains half of the genetic information of the previous cell; early step in sexual reproduction.
Cellular Differentiation - the period of time before cells reach gametogenesis
Gametogenesis - sex cells become mature enough to produce offspring
Homologous chromosomes
Crossing over
Mitosis
- the process of cell division where a single cell divides : in two identical cells; responsible for growth of cells; in sexual reproduction.
Body Cell
Stages
Interphase
- longest part of the cell cycle; chromosomes align and separate; new daughter cells are going to be created during this process
Prophase
- genetic material in the parent cell separates into two identical daughter cells
Metaphase
- chromosomes are being aligned in the middle of the cell
Anaphase
- chromosomes are split into identical daughters
Cytokinesis
Telophase
- the chromosomes are being split one more (final) time in the nucleus of the parent cell
