| Question | Answer |
|---|---|
| haploid, or gamete-producing, phase of an organism | gametophyte |
| diploid, or spore-producing, phase of an organism | sporophyte |
| vascular tissue that carries water upward from the roots to every part of a plant | xylem |
| vascular tissue responsible for the transport of nutrients and the carbohydrates produced by photosynthesis | phloem |
| embryo of a living plant that is encased in a protective covering and surrounded by a food supply | seed |
| type of plant tissue specialized to conduct water | vascular tissue |
| in plants, a cluster of vascular tissue in leaves; in animals, a blood vessel that returns blood to the heart | vein |
| seed plant that bears its seeds directly on the surfaces of cones | gymnosperm |
| flowering plant; bears its seeds within a layer of tissue that protects the seed | angiosperm |
| transfer of pollen from te male gametophyte to the female gametophyte | pollination |
| in gymnosperms, a seed-bearing structure; in the retina of the eye, a photoreceptor that responds to light of different colors, producing color vision | cone |
| food-rich tissue that nourishes a seedling as it grows | endosperm |
| thick wall of tissue surrounding an angiosperm seed | fruit |
| angiosperm whose seeds have one cotyledon | monocot |
| male gametophyte in seed plants | pollen grain |
| angiosperm whose seeds have two cotyledons | dicot |
| seed leaf in a plant embryo | cotyledon |
| flowering plant that lives for more than two years | perennial |
| flowering plant that completes a life cycle within one growing season | annual |
| primary root found in some plants that grows longer and thicker than other roots | taproot |
| part of a root system in which roots branch to such an extent that no single root grows larger than the rest | fibrous root |
| loss of water from a plant through its leaves | transpiration |
| opening in the underside of a leaf that allows carbon dioxide and oxygen to diffuse into and out of the leaf | stomata |
| specialized cell in the epidermis of plants that controls the opening and closing of stomata by responding to changes in water pressure | guard cell |
| outermost circle of flower parts that encloses a bud before it opens and protects the flower while it is developing | sepal |
| the female organs of a flower | pistil |
| male part of the flower; made up of an anther and a filament tip | stamen |
| in algae, a long threadlike colony formed by many green algae; in plants, a long, thin structure that supports an anther | filament |
| flower structure in which haploid male gametophytes are produced | anther |
| narrow stalk of the carpel in a flower | style |
| early growth stage of a plant embryo | germination |
| sticky portion at the top of the style where pollen grains frequently land | stigma |
