stigma
the apical end of the style where deposited pollen enters the pistil
ovary
the organ that bears the ovules of a flower

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

organ containing or producing spores
ascus
saclike structure in which ascospores are formed through sexual reproduction of ascomycetes

fruit
the ripened reproductive body of a seed plant

edible reproductive body of a seed plant especially one having sweet flesh
spore
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

apetalous flower
flower having no petals
inflorescence
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
bud
a partially opened flower
simple pistil
consists of one carpel
compound pistil
consists of two or more fused carpels

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
