| Layers of sporophyte tissues that envelop and protect the megasporangium | ||
| The compiled structure of the megasporangium, megaspore, and their integrument(s) | ||
| A developed form of a microspore, containing the male gametophytes of seed plants | ||
| The transfer of pollen to the part of a seed plant containing the ovules | ||
| Cone-bearing plants | ||
| A transitional species of a seedless vascular plant | ||
| An angiosperm structure specialized sexual reproduction | ||
| Green organs that enclose the flower before it opens | ||
| Brightly colored aids that attract pollinators | ||
| The microsporophylls of a plant, producing microspores that give rise to pollen grains containing male gametophytes | ||
| A stalk making up the stamen | ||
| A terminal sac making up the stamen where pollen is produced | ||
| Megasporophylls that make megaspore and their products, female gametophytes | ||
| A sticky organ that receives pollen | ||
| An entrance to the ovary of a plant | ||
| An organ at the base of a carpel, which contains one or more ovules | ||
| A part of the stem where the whorls of floral organs are attached | ||
| A mature ovary | ||
| The thickened wall of a fruit | ||
| A developed ovule containing a female gametophyte | ||
| The transfer of pollen from the anther of a flower on one plant to the stigma of a different plant of the same species | ||
| A pore in the integuments of the ovule | ||
| A process unique to angiosperms in which two sperm are produced, one of which fertilizes the egg while the other fuses with the two nuclei in the large central cell of the female gametophyte | ||
| An embryonic seed leaf | ||
| A tissue that is rich in starch and other food reserves, produced by repeated division of the central cell female gametophyte | ||
| Species with one cotyledon | ||
| Species with two cotyledons | ||
| A clade consisting of the vast majority of flowering plants that have two embryonic seed leaves, or cotyledons. | ||
| A clade of three early-diverging lineages of flowering plants. | ||
| A flowering plant clade that evolved later than basal angiosperms but before monocots and eudicots. |
