| Frage | Antworten |
| Eukarya | 3rd Domain on tree of life, range from single celled organisms to multicellular |
| Paraphyletic Group | represent some but not all of descendants of single common ancestor |
| Protists 3 Major Things | 1) diverse morphologically 2) diverse in how get food 3) diverse in reproduction |
| algae blooms | toxin producing protist reach high densities in aquatic environment |
| Red Tides | caused by blooms of harmful dinoflagellates |
| symbiosis | when individuals of two different species live in physical contact |
| endosymbiosis | organism lives in another organism |
| Pseudopodia | flexible membrane and dynamic cytoskeleton with ability to surround and swallow prey |
| Absortive Feeding | occurs when nutrients are taken up directly from environment across plasma membrane |
| chloroplast | organelle for photosynthesis |
| amoeboid motion | sliding movement performed by streaming cytoplasm into pseudopodia |
| cilia and flagella | microtubules |
| Green Plants 3 categories | 1) nonvascular 2) seedless vascular 3) seed plants |
| gymnosperms | produce seeds that do not develop in enclosed structure "naked" |
|

Diatoms |
| angiosperms | seeds develop inside protective structure called carpel |
| Formaniferans | |
| gametophyte | multicellular HAPLOID that makes gametes |
| sporophyte | multicellular DIPLOID structure that makes spores |
| ecosystem | all organisms in a particular area along with physical components of environments |
| Cuticle | waxy, watertight sealant that covers above ground parts of plants ***Critical adaptations of land plants*** |
| Stoma (Plural stomata) | gas exchange through opening or pore surrounded by guard cell ***Critical adaptations of land plants*** |
| vascular tissue | allowed early plants to support erect stems and transport water from roots to stems to leaves |
| tracheids | increase surface area on a slant between two cells for diffusion |
| Vessel Elements | specialized vascular tissue (found in gnetophytes and angiosperms) |

|
Dinoflagellates |
| lignin | -structural polymer built with six carbon rings -strengthens cell walls -enables verticality |
| Alteration of Generations 5 Key Events | 1) Haploid gametophytes produce haploid gametes by mitosis 2) 2 gametes unite during fertilization -> zygote 3) zygote divides, mitosis, diploid sporophyte 4) sporophyte making spores 5) sporophyte divide by meiosis |
| gametangia | makes and protects gametes |
| antheridium | sperm-producing |
| archegonium | egg producing |
| Embryophytes | Land Plants |
| homosporous | produce single spore that develops into bisexual gametophyte that produces egg/sperm |
| Heterospory | production of 2 different types of spore producing structures and thus 2 distinct types of spore (male and female) |
| Microsporangia | microspores --> male gametophyte--> sperm |
| Megasporangia | megaspore --> female gametophyte --> eggs |
| whorl | ring of tissue |
| Fruit | reproductive structure that is derived from ovary and encloses one or more seeds |
| monocots | have one cotyledon (grasses) blade leaf |
| Dicots | have two cotyledons (everything that is not grasses) |
| Animals can be recognized by three things | 1. Multicellular 2. Heterotrophs 3. Move under own power |
| 4 features that define animal's body plan | 1. # of embryonic tissue layers 2. cephalization 3. presence/absence of coelom 4. embryo development |
| Epithelium | layer of tightly joined cells that covers body surface |
| Diploblasts | animals whose embryos develop from only two types of tissues, or germ layers: endoderm and ectoderm |
| Triploblasts | animals whose embryos develop from three germ layers: ectoderm, endoderm, and mesoderm |

Bilateral |
| Cephalization | development of head region where structures are more concentrated |
| Coelom | fluid filled body cavity |
| Acoelomates | no coelom |
| Coelomates | posses coelom |
| hydrostatic skeleton | allows soft bodied animals to move even without fins or limbs |
| Cleavage | rapid series of mitotic divisions that forms a mass of cells in developing zygotes |
| Gastrulation | series of cell movements that rearranges the cells to form the gut and embryonic tissue layers |
| Tube-within-a-tube | body plan in which outer tube forms body wall and inner tube forms gut |
| Choanoflagellates | group of protists, closest living relative to animals |
| Suspension Feeders (filter feeders) | capture tiny bits of food by filtering out food particles that are suspended in water or air |
| Deposit Feeders | eat their way through a substrate mouth shape is wormlike and have simple mouthparts |
| Fluid Feeders | suck up or mop up liquids like nectar, blood or fruit juice have mouthparts that allow them to pierce structure to withdraw the fluids inside |
