| Question | Answer |
|---|---|
| terrestrial multicellular eukaryotic photo-autotrophs | plants |

| plants and protists evolved from ______? | green algae (charophytes) |
| cell wall is made of ____ | cellulose |
| synthesizing complexes in the plasma membrane | rosetta-shaped cellulose |
| closest living relatives to plants | charophytes |
| life cycle with 2 multicellular generations Gametophyte (n) Sporophyte (2n) | alternation of generations |
| produces spores | sporangia |
| multicellular organs | sporangia, gametangia |
| female gametophyte | archegonia |
| male gametophyte | antheridia |
| produces gametes | gametangia |
| -get minerals from water -sperm and spores swim thru water | algae |
| -get minerals from soil -water from soil -less water for sperm and spores to swim through | plants |
| non vascular, vascular seedless, seed plants | 3 groups of plants |
| plants without a transport system typically referred to as bryophytes ex) moss | nonvascular |
| plants with a transport system but lack seeds ex) fern | vascular seedless |
| plants with a transport system and produce a seed ex) trees, flowers, and most of plants | seed plants |
| mosses, liverworts, hornworts non wood plants very small or thin | Bryophyta |
| the dominant generation lives longer than sporophyte | gametophyta |
| spores are located on | sporangium |
| extensive deposite of dead organic material | peat |
| vascular tissue with tracheids (tube-shape cells) that transport water and minerals from roots | xylem |
| anchor plant, and also absorb water and nutrients from the soil | roots |
| increase surface area of plant and serve as primary photosynthetic organ | leaves |
| small with single vascular strands | microphylls |
| leaves with highly branching vascular | megaphylls |
| club mosses | phylum lycophyta |
| ferns gametophyte is small and usually grows below surface megaphyll leaves | phylum pterophyta |
| typically microscopic and held within sporangia | seed plants |
| two types of spores are formed | heterospory |
| gives rise to female gemetophytes (within seed) | megaspore |
| gives rise to male gametophytes (within pollen) | microspore |
| embryo, food supply and protective coat | seed |
| humans began cultivating ____ 13,000 years ago | seed plants |
| cypress, pine, sequoia, spruce, fir, and redwood seeds not enclosed in ovary within fruit bud instead are hidden within cones typically have rough, needlelike leaves with thick cuticles | conifers |
| male gametophyte | pollen |
| pellen reaches ovule | pollination |
| seed plants that produce reproductive structures largest group of plants | flowering plants |
| one sperm fertilizes egg, second sperm fertilizes central cell to form endosperm (food supply) | double fertilization |
| plants exhibit ___________ | hierarchy of cells, tissues, organs and systems |
| leaves + roots | shoot system |
| roots | root system |
| depend on shoot system may also store organic nutrients | non-photosynthetic |
| one main root with some lateral roots stores sugar ex) carrot | tap roots |
| mat of thin spreading from just below surface and have NO main root | fibrous root |
| increase surface area for water absorption | root hairs |
| extend from trunk of branches to reach ground | aerial roots |
| aerial roots that support tall, top-heavy plants | prop root |
| support trunks of large trees in tropical forests | buttress root |
| plant germinates on breach of other tree and send roots to the ground while wrapped around host | strangling roots |
| "air-roots" many plants will store food and water in their roots | pneumatophores |
| many plants will store food and water in their roots | storage roots |
| consists of a system of nodes and internodes are modified for specialized functions | stems |
| location at which leaf is attached | node |
| segments between leaves | internodes |
| develop at node and can grow into new branches | axillary buds |
| (terminal) are located at the shoots tip and is responsible for vertical growth of plant | apical buds |
| horizontal underground shoot that grows underground | rhizomes |
| vertical underground shoot that consists mostly of leaves on a shorted stem | bulbs |
| (runners) horizontal surface that forms new plantlets at each node | stolons |
| enlarged end sof rhizomes specialized for storing foots | tubers |
| the main photosynthetic organ typically flat, thin to maximize light penetration may store water and food | leaves |
| types of leaves | simple, compound |
| aid in climbing and supporting weight | tendrils |
| outer protective later herbaceous plants single layer (epidermis) | dermal |
| long-distance transport of materials xylem phloem | vascular |
| all remaining tissue, contains specialized cells for storage and support | ground |
| waxy covering | cuticle |
| multiple layers | periderm |
| internal to vascular | pith |
| external to vascular | cortex |
| located at tips of roots in the buds of shoots provides primary growth (length) | apical meristem |
| responsible for secondary growth girth of thickness extends along the length of roots and shoots | lateral meristem (cambium) |
| adds layers of vascular tissue | vascular cambium |
| replaces the epidermis with periderm (new bark layer) | cork cambium |
| causes african sleeping sickness | trypanosomona |
| causes malaria | plasmodium |
| unique by being mixotrophic and have a rod support inside flagellum | euglenids |
| pseudopodia uses ____ to move | ciliates |
| can create useful energy from non-living material | autotrophic |
| eats to obtain energy | hetertrophic |
| can make food and also eats obtain energy | mixotrophic |
