Bacteria
Bacteria - Prokaryotic cells
- Decomposers - shape -- round, rod shaped, spiral
- Small coccas round, bacillas rod shaped, spairilla spiral
Aggregated
- strepoto - chains
- staphylo - clumps
Gram stain
- pos. purple
-neg. pink When culturing the bacteria.
Protists
Most are single celled organisms
- animal (eats foods) - Paramicium
- plants (make food)
algae - kelp (not single celled)
red, blue, green - different wavelengths -algae, for each color
plants
-volvox - colonial plant
-diatoms - form of phytoplankton
zoe plankton dinophaxulates - bloom red tide
phytoplankton (phisteria) produces toxin
Animals
-move
- cilia - short, hairlike
- flagella - long whip
- pseudopolia - false foot
-do not move
- malaria - caused by protists and cannot move
Fungi
Fungi - kingdom
-hyphae - single fiber - they secreate enzymes to help decompose
-mycelium (fiber) - made up of all fibers
- reproduce with spores
- phylum - zygomycota
- zygospore - sexual reproduction structure mating strains - one pos, one neg.
ex. black bread mold
phylum Assomycota - mushroom - sac fungus - produces ascus - a sac with eight spores
Morel - inside the phylum - yeasts that ferment such as in beer, wine, or bread
phylum - basidiomycota - club fungi (basidium club) with four spores of gills
Fungi cont.
Examples of fungi
Penecilium mold with penecillium
Atheletes foot
lichen - fungus associated with fungi/algae
Virus
Virus - covering, and nucleic material (DNA or RNA)
Virus is a noncellular parasitic agent consisting of an outer capsid and an inner core of nucleic acid. (nonmetabolic)
covering -capsid (protein)
- envelope might not have one
-virus particles-
inner core - nucleic acid (RNA and DNA)
- proteins (enzymes)
all viruses - obligate (only exisit ) as cellular parasites
Viruses do 2 things when infecting cell
Viruses do 2 things when infecting cell:
1. lytic cycle - take over cellular machinary and makes new viruses
2. Lysogenic cycle - genetic material incorporated into cell and hangs out, then switches over to the lytic cycle
Plants
Types of Plants
non-vascular - no conductive tissue (Bryophytes)
^relatively small
Example: moss - reproductive through spores (haploids), the seeds (diploids)
vascular plants
- conducting tissue - roots up
- xylen - conducts water up, dissolves minerals
- phloem - dissolve sugars
Through the veins and leaf
2 groups - seedless - club mosses, ferns, fiddle heads
- seed plants (gymnosperms) naked seeds - no hard cover - gingkos, conifers (cones) - angiosperms (covered seed) flowering plants - eudicots (dicots) , monocotsExample: acorn, corn, oak trees, roses, apples - coevolved with insects
Lytic Cyle, Lysogenic Cycle
Flu - Lytic Cycle (bacterial)
-HIV replication - Lysogenic Cycle
Lytic Cycle - Immediately takes over
Lysogenic Cycle - injects, incorporates material, lies low, and needs trigger to begin
Smaller Infectious things
viroids - naked RNA
Prions - proteinacious (complex fiborous structure) infectious particles
Bovine spongiform encephalothpy (mad cow)
Kretchfeld - Jacob syndrome (people) (mad cow)
Baterialphage
prokaryotes - function - decomposition
- bacteria and archea
- glycocalyx
cellular envelope - cell wall (petidogylcan)
cell - plasma membrane
cell cytoplasm - nucleoid
- ribosomes
- thylakoids (cytonobacteria)
appendages - flagella, conjunction pilus - (flabriae)
Invertebrates, Vertabrates
Invertebrates - no backbone
Vertabrates - Backbone
Phylum - porifera - sponges
- cnidaria - stinging cells
Phylum - platyhelminthes (flat worms)
tapeworms, flukes - parasites
phylum - Nematodes - Round worms
Phylum - Mollusca - squid, octopus
Phylum - Annelida - segmented worms Phylum - Arthropods - jointed legs -shrimp, crab
- Earthworms - crop and a gizzard Phylum - Echinoelermata - spiny skinned -sand dollar
- Leeches
Prokaryotes
Prokaryotes - circular dna plasmid
-nucleoid
- plasmid - pieces of DNA
Binary Fission
- Recombination of DNA - (reproduction)
- conjugation - baacteria temporarily linked together, Dna passes to recipient cell
- transformation - picks up dna from surroundings
- transduction - dna carried from one cell to another
- bacteriophage
- obligate anaerobe (cannot grow with oxygen)
- facultative anerobe -grows with oxygen
Photoautotrophs - use light 4 energy some produce oxygen some do not.
Chemoautotrophs - found in thermal vents - no light for energy
Autoerotrophs
Autoerotrophs
- chemical autoerotrophs - use chemical as energy source
Heterotrophic Bacterial - Ingests Food
Saprotrophs - Eats dead things - (large/small) - decomposer
Symbiotic Relationship
- living together 3 ways
1. commensilism - 1 benefits, 1 no effect
- parasitism - 1 benefits, 1 harmed i.e. tape worms/ ticks
-mutualism - both benefit - sea annemine and clown fish
Pathogens
Parasitic - bacteria - cause disease
- endospores- resistant to death
Example: Anthorax - produce toxins (metabolic by products that are bad for you)
treated with antibiotics such as MRSA
cyanobacteria - photosynthetic i.e. blue, green, algae
symbiotic relationship - lichen - fungi and cyanobacteria
fungi protects and gives inorganic nutrients, cyanobacteria provides food
Archae - oldest
Archae - oldest
- extremophiles - live in extreme enviornments
3 types
1. methanoges - live in bottom of swamps ect.- makes methane
2. Halophiles - salty enviornments
3. Thermoacidophies - different temps cause different changes in bacterial colors
- organge, green, blue
- hot and acidic (Such as Yellow Stone, Dead Sea) releases pressure
Protists
Protists - Most are single cells
Most diverse example ameoba
Domain - Eukaryia
- supergroup - protists are sorted by supergroup - is between eukaryia, and kingdom
-Kingdom
Supergroups - archaeplastids
green algae, at the surface red algae is deeper down
Land plants
Protists cont.
Chromoalreolates - brown algae - kelp
- diatoms - silica shell
Ciliates - cilia shorta nd numerous
- dinoflagelletes - red tide (toxic)
Excavates - flagella or oral groove (leads to mouth)
- Euglenoides (photosynethic/animal)
Amoebozoans
- ameboids - pseudopodia (false feet) such as white blood cells
Opisthokonts
- fungi
- animals
Fungi
Mycelium - (strands all together) hyphae (single strand)
spore - is a reproductive cell that develops into a new organism without the need to fuse with another reprodcutive cell
phylum - basidiomycota - club fungi
Types of fungi
basidium - club - four spores
phylum ascomycota - sac fungi
ascus - sac such as a morel
examples, penicillium, yeasts (fermentation), ringworm, atheletes foot
phlyum zygomycota - sporangiospores (asexual part)
-short gun fungus grows on cow pies , primary decomposers/antibiotics/ commercial sales
Plants
3 organs
leaves - photosynthesis (green - chlorophyll) ex. indian pipe has white stems
stems - hold the leaves
roots - absorb water and dissolved nutrients
roots - fiborous grasses (about the same size/small), taproots - ex. carrots (one/big)
vascular tissue - conducting tissue water from roots, sugars from leaves
xylem - water goes up
phyluem - sugar to all parts
leaves have sylem and phyluem
stems (veins) they run together/ and seperate roots - both tissues in roots
Seed plants
gymnosperms - uncovered seeds
- conifers - cones (holds seeds) no shiny covering
ex. red woods, bristle cone pines
-angiosperms - (flowering plants) dominate plant species (good for reproducing)
ex. oak trees
Chestnuts, rice, wheat barley --- carbohydrates
fruit - seeds - tomato, pepper, squash
carrots - bi annuals
