Prokaryotic Kingdoms:
1) Archaebacteria (“ancient prokaryotes”)
( most are heterotrophic; some are chemoautotrophic
( mostly anaerobic (methanogens, sulfur-bacteria, etc.)
( often live in extreme, harsh environments (thermophiles, acidophiles, salinophiles, etc.)
2) Eubacteria (modern/common prokaryotes)
( mostly heterotrophic; many are autotrophic
( most are helpful (produce vitamins, foods, resistance to diseases, etc.)
( some are pathogenic or opportunistic (strep throat, pneumonia, salmonella, etc.)
Eukaryotic Kingdoms:
Kingdom Protista
( mostly unicellular, some multicellular
( mostly asexual reproduction
Classified based on way they obtain their nutrients:
1) animal-like = heterotrophs = protozoans
2) plant-like = autotrophs = algae
3) fungi-like = saprophytes

Amoeba Paramecium Euglena
2) Kingdom Fungi
( all are saprophytic heterotrophs; most are decomposers
( can be unicellular or multicellular (but do not move at any point in their lives)
( cell wall made of chitin
( includes mushrooms, molds, & mildews
3) Kingdom Plantae
( multicellular, photosynthetic autotrophs
( cell wall made of cellulose
Nonvascular Plants vs. Vascular plants
Examples – mosses conifers & flowering plants
Reproduction – spores (must have water) seeds for all except ferns (spores)
Transport – diffusion & osmosis vascular tissue (xylem & phloem)
Gymnosperms vs. Angiosperms
Seeds – “naked” seeds seed enclosed within a fruit
Variations – male & female cones monocots & dicots
Type of plants – conifers all flowering plants
[pic] [pic] [pic]
Structural adaptations of plants (to life on land):
a) vascular system (water & nutrient transport) d) seeds & fruits (protection & dispersal)
b) flowers (attract pollinators) e) cuticle (prevent water loss)
c) stomata (gas exchange & regulation) f) roots (absorption, anchorage, transport)
4) Kingdom Animalia – multicellular heterotrophs ; cells lack cell walls
Structural adaptations of animals:
Insecta
a) jointed appendages d) exoskeleton (made of chitin) – support & protection
b) mandibles for chewing e) compound eyes
c) spiracles for respiration f) segmented body (head, thorax, abdomen)
Annelida
a) closed circulatory system e) body cavity for complex organs
b) simple brain f) nephridia to excrete metabolic wastes
c) segmented body g) complete internal digestive tract
d) respire through skin h) sexual reproduction, but are hermaphrodites
Amphibian
a) 3-chambered heart e) ectothermic (can’t regulate body temp. internally)
b) respire through lungs & skin f) endoskeleton; vertebrate
c) closed circulatory system g) aquatic and terrestrial life cycle stages
d) undergo metamorphosis h) fertilization is external (must occur in water)
Mammalian
a) hair e) all capable of learning
b) mammary glands (nurse young) f) specialized teeth/jawbone for diet
c) endothermic (herbivore, carnivore, omnivore)
d) 4-chambere heart g) placental = live births (fully developed in uterus)
marsupials = emerge premature & finish developing in pouch
monotremes = lay eggs
Animal Behaviors:
Innate Behavior
a) instincts (suckling, doggie paddling) e) hibernation and estivation
b) reflexes (babinski reflex) f) courtship behavior
c) taxis (movement toward a stimulus) g) “fight-or-flight” response
d) migration (birds, caribou) h) dominance heirarchies and aggression
Learned Behavior
a) habituation (hum of lights) c) trial-and-error learning
b) imprinting (ducks following “momma”) d) conditioning (classical vs. operant)
Social Behavior
a) pheromones – communication via scents
- bees and ants use pheromones to communicate in organized social structures
- animals (e.g. dogs) mark their territory with pheromones
b) courtship dances and/or songs
c) defense of territory (resources)
Coevolution = Evolution between unrelated species.
e.g. pollinators & angiosperms (flowers bright and fragrant; honeybee has mouthparts for reaching nectar;
bee transports pollen from anther on one flower to stigma on another; also = mutualism)
Pathogens = Disease causing agent (e.g. bacteria and viruses).
Viruses considered nonliving – not a cell(s), no life functions (respiration, growth, development, etc.)
Virus Structure – capsid, nucleic acid, envelope, etc.; know bacteriophage (virus that infects bacteria)
Difference between lytic (active) & lysogenic (provirus) cycles
Common Viral Examples: HIV (leads to AIDS) – a retrovirus, influenza, smallpox (has been eradicated)
- viruses can mutate, so that new strains emerge (regularly); think of how the flue changes
every year or so
Genetics and the Environment:
Sickle-cell Anemia
( A genetically inherited disease that distorts the red blood cells and prevents hemoglobin from
functioning (properly).
( Having the sickle cell trait prevents malaria.
( Malaria is caused by the parasitic protist plasmodium. It is transmitted through a mosquito vector
where it lives part of its life cycle.
Cancer – uncontrolled cell division/growth (problem with mitosis)
( Caused by certain genetic predisposition, as well as environmental influences (such as tobacco use)
Skin Cancer – UV rays and genetic predisposition.
Vitamin D may help prevent some cancers.
Folic acid helps aid in cell division and may help prevent some cancers.
Diabetes
( Problem with pancreas secreting insulin. Insulin helps regulate blood sugar homeostasis.
( Caused by a genetic predisposition and the environment (diet) – type 1 vs. type 2
PKU (phenylketonuria)
( Autosomal recessive trait where the body can’t process an amino acid (phenylalanine)
Immune Response:
Killer T-cells – recognize antigens (foreign protein that prompts) from pathogens and kill the cells directly
Helper T-cells – help B-cells turn into plasma cells that produce antibodies.
Memory T-cells – help the immune system respond quickly to a repeat pathogen (antibody already made)
1) Passive Immunity – given antibodies from another source (antibiotics)
2) Active Immunity – the bodies own immune system actively producing the antibodies
Vaccine – a dead/inactive or weakened virus that prompts an immune response
Toxins
Mercury poisoning – Bioaccumulation (biomagnification) in fish can make them toxic and lead to
disease if consumed. Higher on food chain affected most.
Lead poisoning – Can cause brain damage (previously in all paints; now mostly only industrial paints)
