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://

BACTERIA
Coccus-Sphere shape
Bacilius-Rod shape
Spirilium-Spiral shape
