| 648773649 | ovule | a structure that develops within the ovary of a seed plant and contains the female gametophyte | |
| 648773650 | flower | in an angiosperm, a specialized shoot that has structures that function in sexual reproduction | |
| 648773651 | anther | in an angiosperm, the terminal pollen sac of a stamen (connected to a filament) where pollen grains containing sperm-producing male gametophytes form | |
| 648773652 | embryo sac | the female gametophyte of angiosperms, formed from the growth and division of the megaspore into a multicellular structure that typically has 8 haploid nuclei | |
| 648773653 | pollination | the transfer of pollen to the part of a seed plant containing the ovules | |
| 648789149 | seed | an adaptation of some terrestrial plants consisting of an embryo packaged along with a store of food within a protective coat | |
| 648789150 | sepal | a modified leaf in angiosperms that helps enclose and protect a flower bud before it opens | |
| 648789151 | stigma | the sticky part of a flower's carpel which traps pollen grains | |
| 648789152 | cross pollination | in angiosperms, the transfer of pollen from an anther of a flower on one plant to the stigma of a flower on another plant of the same species | |
| 648789153 | conifer | member of the largest gymnosperm phylum. Most conifers are cone-bearing trees, such as pines and firs | |
| 648813824 | petal | a modified leaf of a flowering plant; often colorful parts of a flower that advertise it to insects and other pollinators | |
| 648813825 | style | the stalk of a flower's carpel, with the ovary at the base and the stigma at the top | |
| 648813826 | cotyledon | a seed leaf of an angiosperm embryo. Some species have one cotyledon, others two | |
| 648813827 | micropyle | a pore in the integuments of the ovule | |
| 648813828 | stamen | the pollen-producing reproductive organ of a flower, consisting of an anther and a filament | |
| 648813829 | ovary | in flowers, the portion of a carpel in which the egg-containing ovules develop | |
| 648813830 | endosperm | In angiosperms, a nutrient-rich tissue formed by the union of a sperm with two polar nuclei during double fertilization; provides nourishment to the developing embryo in angiosperm seeds. | |
| 648813831 | integument | layer of sporophyte tissue that contributes to the structure of an ovule of a seed plant | |
| 648825547 | carpel | the ovule-producing reproductive organ of a flower, consisting of the stigma, style, and ovary | |
| 648825548 | dicot | angiosperm with two cotyledons inside its seed, flower parts in multiples of four or five, and vascular bundles in rings | |
| 648825549 | double fertilization | a mechanism of fertilization in angiosperms, in which two sperm cells unite with two cells in the embryo sac to form the zygote and endosperm | |
| 648825550 | monocot | angiosperm with one cotyledon inside its seed, flower parts arranged in multiples of three, and vascular tissues in bundles scattered throughout the stem | |
| 648825551 | filament | in an angiosperm, the stalk portion of the stamen, the pollen-producing reproductive organ of a flower | |
| 648825552 | pollen grain | in seed plants, a structure consisting of the male gametophyte enclosed within a pollen wall |
