1.1 Classifications of Life Flashcards
Taxonomic order (gen to specific)?
kingdom > phylum > class > order > family > genus > species.
Top mnemonic device?
Create a song.
What to remember about archea?
They are (as well as other domain Bacteria) from old kingdom of UNICELLULAR (prokaryotic) organisms Monera.
What to remember about eukaryotics?
While most are multi, they can be unicellular as well.
WHAT TO REMEMBER ABOUT SCHOOL???
MUST REVIEW AND UNDERSTAND NOTES SAME DAY. REVIEW NOTES PERIODICALLY (spaced repetition). 1,3,5,7,14… SEE OG UNI CARDS. Ban head/earphones for a bit.
What to remember in bio?
Understand the meaning of names.
Endosymbiosis?
Eukaryotes came from prokaryotic cells- an archaea (host)/bacteria(symbiont) hybrid. Archea Energy-starved absorbed bacteria as prey but bacteria wasn’t digested and instead put to use. Archaea got ATP (bacteria
Ribosomes?
Not a cell, but a mechanism (no growth = not alive).
chemoorganoheterotrophs:
Energy Source: Organic Compounds Carbon Source: Organic compounds (from other molecules)
chemolithoheterotrophs:
Energy Source: Inorganic Carbon Source: Organic (from other living things)
photoheterotrophs:
Energy source: Light Carbon Source: Organic (can’t make own)
chemoautotrophs:
Energy Source: Organic (oxidation of electron donors) Carbon Source: Makes own from Inorganic
chemolithoautotrophs:
Energy Source: Inorganic Carbon Source: Makes own
Photoautotrophs:
Energy Source: Light Carbon Source: Makes own
What is a cell?
The lowest level of biological systems that can reproduce and is surrounded by membranes?
Membrane?
MAKE SURE TO TOUCH UP ON OLD CONCEPTS YOU MUST CARRY. Separates cell from outside environment.
What is a Plasma Membrane?
Controls movement (in/out) of substances in cell. It is a lipid bilayer with embedded proteins.
What is a nucleoid?
What prokaryotes have instead of a nucleus. Region in cell that contains genetic information.
cell wall vs cell membrane?
Cell wall is rigid and protects cell from outside environment. Present in Bacteria, Fungi, and Plant cells (ie eukaryotes too). Cell wall is non-living and not involved in metabolism- unlike cell membrane.
What to remember about fungi?
They are eukaryotes.
Best Test Strategy?
Test yourself before studying. Check/ask for prof. resources or look up practice test.
What to look back at before successive tests?
Old exam results + take notes from it. BE THOROUGH.
