Reproduction Unit - Lesson 9 - Emma Pentcheva 10/2
Processes
Types of Reproduction
Asexual
Mitosis - is also a process that results in a clone/identical cell. The body cells do this.
Body Cell - It can differentiate based on the protein it makes. Applies only to mitosis.
Cellular Differentiation - It is the concept that different proteins made in a cell give it a different role in the organism. The body cells do this
Runner
Is a process that results in a clone/identical cell. As well as that, it does not involve another organism to do so.
Sexual
Meiosis - This is a process in which crossing over occurs (in the chromosomes); all of these stages occur twice so that they can 4 unique haploid cells
Gamete
Gametogenesis- Literally means “the creation of sex cells”
Oovogenesis - The creation of ovum/eggs
Ovum/egg - Often has a thick layer on the outside to make it challenging for a sperm to enter
Spermatogenesis - The creation of Sperm
Sperm - A cell that is able to move itself
Interphase - All the DNA is replicated; now we have 92 chromosomes
Prophase - Chromosomes condense and crossing over occurs
Metaphase - Chromosomes line up in the middle
Anaphase - Homologous chromosomes move to the opposite poles of the cell
Telophase - 2 cells are formed; each with 46 unique chromosomes

Homologous chromosomes
Crossing over
It produces a unique offspring
Types of Fertilization
External - This is a process in which the gametes (sperm and egg) meet outside of an organism
Internal - This is a process in which the gametes (sperm and egg) meet inside an organism
Organisms
Single-Celled - An organism made of only 1 cell
Bacteria
Prokaryotic - Organisms that don't have a true nucleus
Multicellular - An organism made of more than 1 cell
Chicken
Eukaryotic - Organisms that have a true nucleus
Coral
Human
Female Reproductive System
Ovary - This is where the eggs are made
Fallopian Tubes - Where the eggs are released and fertilized
Zygote
Diploid - cells that contain 46 chromosomes; a set from each parent
Embryo
Fetus
Uterus
Uterus Lining
Cervix
Vagina
Male Reproductive System
Testis - where sperm develops
Vas Deferens - sperm travels through here to get to the prostate gland
Prostate Gland - fluids are added to the sperm making semen
Penis
Urethra - found within the penis
Flowers
Potato (plant)
