VOCABULARY Embryology-the branch of biology that studies the

formation and early development of a living species. Embryo-From implantation to 8 weeks Fetus-After 8 weeks Fertilization-Egg and sperm come together to form

a zygote Zygote-Fertilized egg Cleavage-First few mitotic divisions of the zygote Morula-Solid ball of cells

VOCABULARY (CONTINUED) Blastula-Fluid filled ball of cells Implantation-When the blastula attaches to the

uterine wall Gastrulation-When the blastula forms three germ

layers called a gastrula Gastrula-3 germ layers are formed Endoderm-Innermost layer (digestive track) Mesoderm-Middle layer (internal organs) Ectoderm-Outermost layer (skin and nervous

system) Stem Cells-Unspecialized body cells

STAGES Zygote

Fertilized egg Morula

Solid ball of cells Blastula

Fluid-filled ball of cells Gastrula

3 germ layers

PROCESSES Fertilization

Egg and sperm cells meet

ImplantationMorula implants into

the uterine wall Gastrulation

Blastula forms 3 germs layers and becomes gastrula

VOCABULARY

Virus-Non-living particles that need a host cell to survive

Lytic Cycle-Instant virus reproduction Lysogenic Cycle-Viruses hide in host

until signaled to replicate Vaccine-Dead or weakened virus that

improves the immunity to a particular disease

VOCABULARY (CONTINUED) Bacteria-Unicellular prokaryotic cells Obligate Aerobe-Requires oxygen Obligate Anaerobe-Requires complete lack of oxygen Faculative Anaerobe-Does not need oxygen, but can use it Binary Fission-Process that allows bacteria to replicate

(identically) Conjugation-When bacterium exchange genetic information Endospore-Allows bacteria to go dormant when conditions

are unfavorable Antibiotic-Drugs that combat bacteria by interfering with

various cellular functions Antibiotic Resistance-Bacteria’s ability to be resistant to

certain antibiotics

VIRUSES Bacteriophage-Virus that attacks bacteria Tobacco Mosaic Virus-Virus that attacks tobacco

plants Ebola-Animal virus HIV (Human Immunodeficiency Virus)- Leads to

AIDS (retrovirus) Influenza Virus-RNA containing virus http://
