spore - a small usually single-celled reproductive body produced by many plants and some protozoans and that develops into a new individual; "a sexual spore is formed after the fusion of gametes"

fructification - organs of fruiting (especially the reproductive parts of ferns and mosses)

gleba - fleshy spore-bearing inner mass of e.g. a puffball or stinkhorn

hymenium - spore-bearing layer of cells in certain fungi containing asci or basidia

sporocarp, spore case - specialized leaf branch in certain aquatic ferns that encloses the sori or clusters of sporangia

blossom, flower, bloom - reproductive organ of angiosperm plants especially one having showy or colorful parts

stamen - the male reproductive organ of a flower

anther - the part of the stamen that contains pollen; usually borne on a stalk

pistil - the female ovule-bearing part of a flower composed of ovary and style and stigma

style - (botany) the narrow elongated part of the pistil between the ovary and the stigma

stigma - the apical end of the style where deposited pollen enters the pistil

ovary - the organ that bears the ovules of a flower

ovule - a small body that contains the female germ cell of a plant; develops into a seed after fertilization

placenta - that part of the ovary of a flowering plant where the ovules form

placentation - arrangement of the ovules in the placenta and of the placentas in the ovary

episperm, seed coat, testa - protective outer layer of seeds of flowering plants

endosperm - nutritive tissue surrounding the embryo within seeds of flowering plants

gemma - small asexual reproductive structure in e.g. liverworts and mosses that detaches from the parent and develops into a new individual

strobile, strobilus, cone - cone-shaped mass of ovule- or spore-bearing scales or bracts

basidium - a small club-shaped structure typically bearing four basidiospores at the ends of minute projections; unique to basidiomycetes

plant organ - a functional and structural unit of a plant or fungus

antheridium - the male sex organ of spore-producing plants; produces antherozoids; equivalent to the anther in flowers

sporangium, spore case, spore sac - organ containing or producing spores

ascus - saclike structure in which ascospores are formed through sexual reproduction of ascomycetes

sporophore - a spore-bearing branch or organ: the part of the thallus of a sporophyte that develops spores; in ferns and mosses and liverworts is practically equivalent to the sporophyte

gametangium - cell or organ in which gametes develop

gametoecium - gametangia and surrounding bracts

gametophore - a modified branch bearing gametangia as in the thalloid liverworts

sorus - cluster of sporangia usually on underside of a fern frond

sorus - a spore-producing structure in certain lichens and fungi

fruit - the ripened reproductive body of a seed plant
