Intro Flashcards
3 main components of cell
plasma membrane, cytoplasm, genetic material
lacks nuclear membrane
prokayryote
bacteria and archaea are what
prokaryote
have nuclear membrane
eukaryote
plants and animals are what
eukaryote
chronological order of 3 domains of life
- bacteria, 2. archaea 3. eukaryea
inhabit soil, surface waters, and the tissues of other living or decaying organisms
bacteria
inhabit extreme enviroments
archaea
all eukaryotic organisms
eukarya
Plentiful supply of O2, organisms transfer electrons from fuel to o2 for energy
aerobic
devoid of O2, organisms transfer electrons to nitrate sulfate, or CO2 for energy
anaerobic
die when exposed to O2
obligate anaerobes
can live wit her without O2
facultative anaerobes
composed of plasma membrane, outer membrane, and peptidoglycan
cell envelopec
cell envelope function
increases rigidity
what is unique to animal cells
lysosomes
harvests sunlight, produces ATP and carbohydrates
chloroplasts
temporarily stores carbs
starch granule
thylakoids
site of light driven ATP syn
provides shape and rigidity, protects cell from osmotic swelling
cell wall
degrades and recycles macromolecules, stores metabolites
vacuole
provides path btw two plant cells
plasmodema
contains enzymes of the glyoxylate cycle
glyocysome
what are macromolecules made of
monomeric units
what do macromolecules make
supramolecular complexes
4 elements essential to animal life and health
H, C, N, O
molecule with the same chemical formula and bonds, but diff confg
stereoisomer
