| 5951944951 | plants | *--*dominant photosynthetic organisms on planet *--*eukaryotic cells *--*multicellular *--*cell walls are made of cellulose *--*exhibit alternation of generations | 0 | |
| 5951944952 | alternation of generations | the alternation between the haploid gametophyte and the diploid sporophyte in a plant's life cycle |  | 1 |
| 5951944953 | gametophyte | the stage in the life cycle of a plant in which the plant produces gametes, or sex cells **egg or sperm, haploid generation | 2 | |
| 5951944954 | sporophyte | the stage in the life cycle of a plant in which the plant produces haploid spores **spore or seed, diploid generation | 3 | |
| 5951944958 | Plants (and classification of) show evolution from... | water to land |  | 4 |
| 5951944959 | What did plants develop to solve most of the problems of transition from water to land? | vascular tissue seeds cuticle stomata | 5 | |
| 5951944960 | xylem | vascular tissue that carries water and dissolved minerals from the roots of a plant to its leaves. one direction **in charge of water | 6 | |
| 5951944961 | phloem | vascular tissue through which food moves in some plants **in charge of food (phloem and food both start with F...?) | 7 | |
| 5951944962 | Bryophytes | Mosses *--*do NOT have vascular tissue *--*found in damp, wet areas close to the ground *--*instead of growing vertically, they grow horizontally *--*do NOT produce seeds; produce spores *--*do NOT produce fruit |  | 8 |
| 5951944963 | Pteridophytes | *--*Pteridophytes *--*do have vascular tissue *--*found in wet areas, usually under trees, because they have to have water for reproduction (for the sperm to swim) *--*do NOT produce seeds; produce spores *--*do NOT produce fruit |  | 9 |
| 5951944964 | Gymnosperms | *--*do have vascular tissue *--*can be found anywhere, really *--*due to wind, pollen carries sperm to cone, which fertilizes egg and produces seeds *--*do NOT produce fruit |  | 10 |
| 5951944965 | Angiosperms | Most complex *--*can be found anywhere except really cold environments *--*do have vascular tissue *--*do produce seeds *--*do produce fruit (purpose: to disperse seeds) |  | 11 |
| 5951944966 | self pollination | the transfer of pollen from one flower to another flower on the same plant |  | 12 |
| 5951944967 | cross pollination | a reproductive process in which pollen from one plant is transferred to the stigma of another plant |  | 13 |
| 5951944969 | transpiration | process within plants that is a loss of water in vapor form; it occurs due to plants opening stomata to take in CO2 (regulated by guard cells) |  | 14 |
| 5951944972 | Why would a plant want to get rid of water? | to get "new" water into the plant, you've got to get rid of some of the "old" water a plant needs to make room for "new" water in order to distribute food throughout the phloem of the plant | 15 | |
| 5951944976 | tropism | a growth response of a plant toward or away from a stimulus (basically a response to a stimulus) **often caused by hormones | 16 | |
| 5951944977 | thigmotropism | plant response to contact i.e. vines growing around something |  | 17 |
| 5951944978 | phototropism | plant response to light **flowers bend toward the sun |  | 18 |
| 5951944979 | gravitropism | response of a plant to the force of gravity |  | 19 |
| 5951944980 | positive tropism | plant response towards stimulus | 20 | |
| 5951944981 | negative tropism | plant response away from stimulus | 21 | |
| 5951944982 | hormones | chemical substances (very simple structures) produced at one location and used at other locations They are effective in very small quantities and can cause a "cascade effect". | 22 | |
| 5951944983 | cytokinins | plant hormones that stimulate cell division; they are produced in large quantities in plant roots | 23 | |
| 5951944984 | auxins (indole acetic acid - IAA) | plant hormones that lead to phototropism by elongating the dark side of the plant and affect turgor pressure **causes cell elongation (causes plants to bend) |  | 24 |
| 5951944988 | gibberellins (GAs) | Hormone that promotes stem elongation | 25 | |
| 5951944989 | ethylene gas | gaseous plant hormone responsible for fruit ripening (example of positive feedback) **ripe fruit give off ethylene gas | 26 | |
| 5951944990 | abscisic acid | A plant hormone that brings about dormancy in buds, mantains dormancy in seeds, and brings about stomatal closing, among other effects. Produced in stressful situations | 27 | |
| 5951944992 | photoperiodism | a plant's response to seasonal changes in length of night and day (particularly with flowering) **length of dark period determining factor | 28 | |
| 5951944994 | long day plant | plant which critical photoperiod must be surpassed in order for it to flower **begin forming flower buds when the days are longer than their critical day length | 29 | |
| 5951944995 | short day plant | plant which flowers until the critical photoperiod is passed; then becomes vegetative **begin flowering when the days are shorter than their critical day length | 30 | |
| 5952028868 | water potential | direction water will flow, impacted by solute concentration and pressure | 31 |
