| Question | Answer |
|
Abiotic
Image:
Ab (binary/octet-stream)
|
Not derived from living organisms |
| Anaerobic & AerobIc | without oxygen & with oxygen |
|
Prokaryotes
Image:
Pro (binary/octet-stream)
|
No nucleus or organelles ; live in harsh environments Ex. Archea |
| Chemo-synthetic | Uses inorganic molecules as a source of energy & converts them into organic substances |
| Heterotrophs & Autotrophs | Cannot synthesis its own food so must eat other things to survive & Synthesizes its own food from non-living things |
|
Endosymbiosis &
Endosymbiotic Theory
Image:
End (binary/octet-stream)
|
Two organisms in close association over a long period of time Large prokaryote engulfed smaller ones (mitochondria & chloroplasts) |
|
5 Major Extinctions
Image:
Dino (binary/octet-stream)
|
Ordivication: oldest end- Devonian: marine species Permian: biggest end- Triassic: asteroid or volcano Cretaceous: killed dinos (Holecene / Anthropocene: climate change & people?) |
|
8 Taxa (largest to smallest)
Image:
Taxa (binary/octet-stream)
|
Domains (3) Kingdoms (6) Phylum, Class, Order Family, Genus & species |
| Lytic Cycle (Virulent Phages reproduce this way) | 1. Attachment 2. Penetration (Phage DNA enters) 3. Biosynthesis 4. Assembly 5. Release |
| Lysogenic 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 |
|
Domain #1 Bacteria
Image:
960x0 (binary/octet-stream)
|
auto & hetero unicellular prokaryote (no nucleus) has Peptidoglycan in cell wall ex. terburculosis |
|
Domain #2 Archea
Image:
Archea (binary/octet-stream)
|
auto & hetero unicellular prokaryote (no nucleus) NO Peptidoglycan in cell wall ex. extremophiles |
|
Domain # 3 Eukarya
Image:
Euk (binary/octet-stream)
|
4 Kingdoms auto & hetero uni or multi cellular eukaryotes (have nucleus) |
| Eukarya > Protista | auto & hetero Cell Wall = Cellulose ex. Giant Kelp |
| Eukarya > Fungi | Heterotroph only Cell Wall = Chitin ex. mushroom |
|
Eukarya > Plantae
Image:
Sunfl (binary/octet-stream)
|
Autotroph only Cell Wall = Cellulose / Fiber ex. Sunflower |
| Eukarya > Animalia | Heterotrph only Cell Wall = NONE ex. Sponge |
| Sporophyte | Asexual phase (2n) makes haploid spores by meiosis ex. the tree stage Spores > Meiosis > Gametophyte Gen |
| Gametophyte | Sexual phase (n) Makes gametes (sperm & egg) w/ mitosis ex. pollination Dependent on Sporophyte Gen |
| Tracheids | 1 of 2 Xylem cells: dead, long, thin, moves water and passes through pits (region without cell wall) |
| Vessel Elements | 2 of 2 Xylem cells: dead, aligned end-to-end found mainly in angiosperms (encased seeds) |
| Sieve-tube Elements | 1 of 2 Phloem cells: alive, chains of pores for transport with sieve plates |
| Companion Cells | 2 of 2 Phloem cells: alive, connected to sieve tubes by plasmodesmata |
| 1. Epidermis (roots & shoots) | Outer tissue in plants |
| 2. Cortex / Endodermis (roots & shoots) | Inner with Ground Tissue |
|
3. Stele (roots & shoots)
Image:
Stele (binary/octet-stream)
|
Vascular Bundle & Pericycle (outer layer that produces secondary roots) |
| Petiole | Connects leaf to stem |
| 1. Epidermis (leaf) | Top & bottom of leaf; cuticle & stomata |
| 2. Mesophyle (leaf) | Spongy region sandwiched between lower & upper epidermis where photosynthesis happens |
| 3. Vascular Tissue Bundle (leaf) | Xylum & Phloem live here; continues with stem |
| Male Plant Organs | Stamen (Anther (top) & Filament (long)) |
| Female Plant Organs | Pistil (singlular) / Carpel (multiple) (Stigma (top), Style (long) Ovary) |
|
Parts of Plant Embryo
Image:
Embr (binary/octet-stream)
|
Epicotyle = becomes shoot tip Hypocotyle = terminates in radicle Radicle = embryonic root |
