an asexual reproductive cell
organs of fruiting (especially the reproductive parts of ferns and mosses)
fleshy spore-bearing inner mass of e.g. a puffball or stinkhorn
spore-bearing layer of cells in certain fungi containing asci or basidia
spore case, sporocarp
specialized leaf branch in certain aquatic ferns that encloses the sori or clusters of sporangia
bloom, blossom, flower
reproductive organ of angiosperm plants especially one having showy or colorful parts
the male reproductive organ of a flower
the part of the stamen that contains pollen; usually borne on a stalk
the female ovule-bearing part of a flower composed of ovary and style and stigma
(botany) the narrow elongated part of the pistil between the ovary and the stigma
the apical end of the style where deposited pollen enters the pistil
the organ that bears the ovules of a flower
a small body that contains the female germ cell of a plant; develops into a seed after fertilization
that part of the ovary of a flowering plant where the ovules form
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
nutritive tissue surrounding the embryo within seeds of flowering plants
small asexual reproductive structure in e.g. liverworts and mosses that detaches from the parent and develops into a new individual
cone, strobile, strobilus
cone-shaped mass of ovule- or spore-bearing scales or bracts
a small club-shaped structure typically bearing four basidiospores at the ends of minute projections; unique to basidiomycetes
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
saclike structure in which ascospores are formed through sexual reproduction of ascomycetes
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
cell or organ in which gametes develop
gametangia and surrounding bracts
a modified branch bearing gametangia as in the thalloid liverworts
cluster of sporangia usually on underside of a fern frond
a spore-producing structure in certain lichens and fungi
the ripened reproductive body of a seed plant
edible fruit
edible reproductive body of a seed plant especially one having sweet flesh
a small usually single-celled asexual reproductive body produced by many nonflowering plants and fungi and some bacteria and protozoans and that are capable of developing into a new individual without sexual fusion
juniper berry
berrylike fruit of a plant of the genus Juniperus especially the berrylike cone of the common juniper
floret, floweret
a diminutive flower (especially one that is part of a composite flower)
apetalous flower
flower having no petals
the flowering part of a plant or arrangement of flowers on a stalk
ray floret, ray flower
small flower with a flat strap-shaped corolla usually occupying the peripheral rings of a composite flower
a partially opened flower
simple pistil
consists of one carpel
compound pistil
consists of two or more fused carpels
a sterile vestigial pistil remaining in a staminate flower
an enlargement at the base of the style in some Umbelliferae
a simple pistil or one element of a compound pistil
amphitropous ovule
a partly inverted ovule turned back 90 degrees on its stalk
anatropous ovule
a completely inverted ovule turned back 180 degrees on its stalk
campylotropous ovule
a curved ovule with the micropyle almost touching the funiculus
orthotropous ovule
a completely straight ovule with the micropyle at the apex
apical placentation
where one or few ovules develop at the top of a simple or compound ovary
axile placentation
ovules are borne at or around the center of a compound ovary on an axis formed from joined septa
basal placentation
where one or few ovules develop at the base of a simple or compound ovary
free central placentation
where ovules develop on a central column in a compound ovary lacking septa or with septa at base only
lamellate placentation
with ovules on thin extensions of the placentae into a compound ovary
marginal placentation, ventral placentation
with ovules borne on the wall along the ventral suture of a simple ovary
parietal placentation
where ovules develop on the wall or slight outgrowths of the wall forming broken partitions within a compound ovary
fir cone
the seed-producing cone of a fir tree
the seed-producing cone of a cypress tree
the seed-producing cone of a pine tree
a mature fertilized plant ovule consisting of an embryo and its food source and having a protective coat or testa
macrosporangium, megasporangium
a plant structure that produces megaspores
a plant structure that produces microspores
May apple
edible but insipid fruit of the May apple plant
the flower of a chrysanthemum plant
small dry indehiscent fruit with the seed distinct from the fruit wall
corn silk, cornsilk
each of the long filamentous styles that grow as a silky tuft at the tip of an ear of Indian corn
any of numerous inedible fruits with hard rinds
prairie gourd
small hard green-and-white inedible fruit of the prairie gourd plant
blue fig, quandong
the fruit of the Brisbane quandong tree
fruit of the oak tree: a smooth thin-walled nut in a woody cup-shaped base
small ovoid fruit of the European olive tree; important food and source of oil
hip, rose hip, rosehip
the fruit of a rose plant
wild cherry
the fruit of the wild cherry tree
small bitter fruit of the marasca cherry tree from whose juice maraschino liqueur is made
small cherry much liked by birds
the fruit of the chokecherry tree
decorative red berrylike fruit of a rowan tree
buffalo nut, elk nut, oil nut
oily drupaceous fruit of rabbitwood
the basidium of various fungi
gametophore bearing antheridia as in certain mosses and liverworts
a sporangium that arises from a group of epidermal cells
a sporangium formed from a single epidermal cell; characteristic of the Filicales or of almost all modern ferns
a sporangium containing four asexual spores
a female gametoecium
a male gametoecium
capitulum, ear, spike
fruiting spike of a cereal plant especially corn
a diminutive fruit, especially one that is part of a multiple fruit
a small hard fruit
a small fruit having any of various structures, e.g., simple (grape or blueberry) or aggregate (blackberry or raspberry)
aggregate fruit, multiple fruit, syncarp
fruit consisting of many individual small fruits or drupes derived from separate ovaries within a common receptacle: e.g. blackberry; raspberry; pineapple
