| pistil | female part of a flower |
| stamen | male part of a flower |
| ovary | part of flower that becomes fruit when mature |
| ovule | part of flower that becomes a seed when mature |
| pollen | produces at tipes of stamen, contains sperm |
| sepal | green parts of flower that protect bud |
| petals | often colorful and fragrant, help attract pollinators |
| stomates | openings in a leaf that allow gas exchange, ususally more on lower epidermis |
| guard cells | surround stomates and control size of the opening |
| palisade layer | section of a leaf where most photosynthesis occurs |
| spongy layer | section of leaf that contains many air spaces |
| cuticle | thin, waxy coating that keeps leaf waterproof |
| nitrogen fixation | process where bacteria turn nitrogen into ammonia, happens in soil and on roots of legumes |
| nitrification | process of turning ammonia into nitrates, done by bacteria in soil |
| carbon dioxide | gas given off by burning fossil fuels, decomposition and decay, and respiration |
| oxygen | gas used during respiration, given off during photosynthesis |
| transpiration | process where water is lost through stomates by evaporation |
| taiga | biome with many coniferous trees, "spruce/moose biome" |
| tundra | coldest biome, permafrost, arctic hares and polar bears |
| temperate deciduous forest | biome we live in, four seasons, most trees lose leave in winter |
| desert | biome with very little rain, animals and plants adapted to conserve water, hot days, cool nights |
| savannah | grazing animals, such as zebras and gazelles, rainy season |
| temperate grassland | long roots on plants, few big trees, animals such as prairie dogs |
| rainforest | greatest amount of precipitation, constant temperature, diversity of species |
| mutualism | symbiotic relationship where both organisms benefit |
| commensalism | symbiotic relationship where one organism benefits, other unharmed |
| parasitism | symbiotic relationship where one organism benefits, other is harmed |
| host | organism that a parasite lives on/in |
| endoparasite | organism, such as tapeworm or virus, that lives inside host |
| ectoparasite | organism, such as leech or tick, that lives attached to outside of host |
| proteins | organic compound that contains nitrogen |
| carbohydrates | organic compound made during photosynthesis |
