- 1AbioticNot derived from living organisms
- 2Anaerobic & AerobIcwithout oxygen & with oxygen
- 3ProkaryotesNo nucleus or organelles ;
live in harsh environments
Ex. Archea
- 4Chemo-syntheticUses inorganic molecules as a source of energy & converts them into organic substances
- 5Heterotrophs & AutotrophsCannot synthesis its own food
so must eat other things to survive
&
Synthesizes its own food
from non-living things
- 6Endosymbiosis & Endosymbiotic TheoryTwo organisms in close association
over a long period of time
Large prokaryote engulfed smaller ones (mitochondria & chloroplasts)
- 75 Major ExtinctionsOrdivication: oldest end-
Devonian: marine species
Permian: biggest end-
Triassic: asteroid or volcano
Cretaceous: killed dinos
(Holecene / Anthropocene:
climate change & people?)
- 88 Taxa (largest to smallest)Domains (3)
Kingdoms (6)
Phylum, Class, Order
Family, Genus & species
- 9Lytic Cycle (Virulent Phages reproduce this way)1. Attachment
2. Penetration (Phage DNA enters)
3. Biosynthesis
4. Assembly
5. Release
- 10Lysogenic Cycle (Temperate Phages reproduce by both cycles)1. Viral DNA incorp. into bacteria
2. cell & prophage reproduce
3. Remains inactive until stimulated
4. after stimulation, switches to Lytic Cycle
- 11Domain #1 Bacteriaauto & hetero
unicellular
prokaryote (no nucleus)
has Peptidoglycan in cell wall
ex. terburculosis
- 12Domain #2 Archeaauto & hetero
unicellular
prokaryote (no nucleus)
NO Peptidoglycan in cell wall
ex. extremophiles
- 13Domain # 3 Eukarya4 Kingdoms
auto & hetero
uni or multi cellular
eukaryotes (have nucleus)
- 14Eukarya > Protistaauto & hetero
Cell Wall = Cellulose
ex. Giant Kelp
- 15Eukarya > FungiHeterotroph only
Cell Wall = Chitin
ex. mushroom
- 16Eukarya > PlantaeAutotroph only
Cell Wall = Cellulose / Fiber
ex. Sunflower
- 17Eukarya > AnimaliaHeterotrph only
Cell Wall = NONE
ex. Sponge
- 18SporophyteAsexual phase (2n)
makes haploid spores by meiosis
ex. the tree stage
Spores > Meiosis > Gametophyte Gen
- 19GametophyteSexual phase (n)
Makes gametes (sperm & egg) w/ mitosis
ex. pollination
Dependent on Sporophyte Gen
- 20Tracheids1 of 2 Xylem cells:
dead, long, thin, moves water and passes through pits (region without cell wall)
- 21Vessel Elements2 of 2 Xylem cells:
dead, aligned end-to-end found mainly in
angiosperms (encased seeds)
- 22Sieve-tube Elements1 of 2 Phloem cells:
alive, chains of pores for transport with sieve plates
- 23Companion Cells2 of 2 Phloem cells:
alive, connected to sieve tubes by plasmodesmata
- 241. Epidermis (roots & shoots)Outer tissue in plants
- 252. Cortex / Endodermis (roots & shoots)Inner with Ground Tissue
- 263. Stele (roots & shoots)Vascular Bundle & Pericycle
(outer layer that produces secondary roots)
- 27PetioleConnects leaf to stem
- 281. Epidermis (leaf)Top & bottom of leaf; cuticle & stomata
- 292. Mesophyle (leaf)Spongy region sandwiched between lower & upper epidermis where photosynthesis happens
- 303. Vascular Tissue Bundle (leaf)Xylum & Phloem live here;
continues with stem
- 31Male Plant OrgansStamen
(Anther (top) & Filament (long))
- 32Female Plant OrgansPistil (singlular) / Carpel (multiple)
(Stigma (top), Style (long) Ovary)
- 33Parts of Plant EmbryoEpicotyle = becomes shoot tip
Hypocotyle = terminates in radicle
Radicle = embryonic root
