Organismal Bio Flashcards
What is the first level of biological organization?
Molecules - DNA, RNA, proteins ect.
Example: DNA is a type of molecule.
What is the second level of biological organization?
Organelles - Mitochondria, golgi apparatus, ect.
Example: The mitochondria is known as the powerhouse of the cell.
What is the third level of biological organization?
Cells - unit of life
What is the fourth level of biological organization?
Tissues - groups of cells united for a common function, many different kinds of cells.
What is the fifth level of biological organization?
Organs - a group of different kinds of tissues united for a common function, like lungs, stomach.
What is the sixth level of biological organization?
Organ Systems - a group of organs united for a common function, Digestive system, intestines.
What is the seventh level of biological organization?
Organism - organ systems together
What is the eighth level of biological organization?
Population level - above level of organisms
What is the ninth level of biological organization?
Community Level - Biological components that interact, competition, pretitor/prey
What is the tenth level of biological organization?
Ecosystem Level - Biotic + Abiotic components
What is the eleventh level of biological organization?
Biosphere - global warming
Domains
Bacteria, Archaea, Eukarya.
.Order of Things
Domain, Kingdom, Phylum, Class, Order, Family, Genus, Species.
Feed themselves by light, many Projaryotes and Eukaryotic plants (Green) - capture solar energy CO2 and water.
organism that uses energy from sunlight to convert carbon dioxide and water to carbon compounds
Photoautotrophs
Feed themselves by light, many Projaryotes and Eukaryotic plants (Green) - capture solar energy CO2 and water.
organism that uses energy from sunlight to convert carbon dioxide and water to carbon compounds
Photoautotrophs
Rare - only in Projaryotes (H2s, NH3) feed themselves with Chemicals (FE3+)
Chemoautotrophes
Capture sunlight, but can also eat other things - rare, can do photo + organic carbon found only in some marine prokaryotes.
organism that is photosynthetic but needs organic compounds as a carbon source
Photoheterotrophes
eat chemicals form outside of body - many prokaryotes, protists, fungi, and animals.
organism that must take in organic molecules for both energy and carbon
Chemoheterotrophes
Modes of Respiration
With Oxygen
Without Oxygen
chemical oxidations - US
Fermentation
Modes of respiration
Organisms
a. must have O2
b. cannot tolerate O2
c.can use both O2 and can Fermentate if O2 is absent.
a. Obligate Aerobics
b. Obligate Anaerobic
c.Facilitative Anaerobics
Love Extreme Environments
Archaea
eukaryotic one-celled living organisms distinct from multicellular plants and animals: protozoa, slime molds, and eukaryotic algae
Protista
eukaryotic one-celled living organisms distinct from multicellular plants and animals: protozoa, slime molds, and eukaryotic algae
Protista
One common ancestor that give life to other branches of the group. All decedents of that group are members. Cladistics - true clade is monophyletic.
Monophyletic
One common ancestor that give life to other branches of the group. All decedents of that group are members. Cladistics - true clade is monophyletic.
Monophyletic
Paraphyly
Lacks some ancestral species.
Polyphyly
A nested group within a larger group. Cladistics - true clade is monophyletic
Clade
A nested group within a larger group. Cladistics - true clade is monophyletic
Clade
Have two nuclei and multiple flagella.
Disease “beaver fever” caused be giardia intestinalis.
Diplomonads
Have two nuclei and multiple flagella.
Disease “beaver fever” caused be giardia intestinalis.
Diplomonads
Disease organisam, Trichomonas Vaginalis.
A group of protistans, including the trichomonads, that lacks mitochondria.
Parabasalids
