Exempel på hur man kan använda PENTAMEROUS i en mening

• While bilaterally symmetrical as larvae, as adults echinoderms are recognisable by their usually five-pointed radial symmetry (pentamerous symmetry), and are found on the sea bed at every ocean depth from the intertidal zone to the abyssal zone.
• Species are, however, united by their simple and opposite leaves and typically have showy pentamerous flowers (flowers in which components occur in multiples of five) and show nuclear endosperm formation (in which cell division takes place without the cell wall forming between divisions).
• They are usually perfectly pentamerous and pentacyclic without fused organs besides the carpels of the superior gynoecium.
• The flower is pentamerous (except for a few Southeast Asian species) and ripens into an indehiscent fruit with numerous seeds.
• Myosotis species are annual or perennial, herbaceous, flowering plants with pentamerous actinomorphic flowers with five sepals and petals.
• Formerly included in the genera Myrtus and Psidium, Accara differs from the latter in embryo structure, and from the former in being pentamerous (having its parts in fives) and in bud structure.
• Both have male flowers and female flowers, not hermaphrodite as in Hecastocleis, while Gymnarrhena has (trimerous or) tetramerous male florets, not pentamerous.
• Small, axillary, 2–3 in a cluster; pedicels jointed at the middle, epicalyx absent, complete, bisexual, regular, actinomorphic, hypogynus, pentamerous, yellow.
• Other asterids that have flower heads with only one floret are Corymbium, Hecastocleis shockleyi, Stifftia uniflora and Fulcaldea laurifolia, but these are pentamerous and hermaphrodite.
• The pentamerous Arkarua is older, dating from the late Precambrian, but with existing fossils of this organism showing no evidence of having stereoms, its status as an edrioasteroid echinoderm remains under much discussion.
• Flowers: Bracteate, bracteolate, bracteoles two, shorter than perianth, dry, membranous and persistent, sessile, complete, hermaphrodite, actinomorphic, pentamerous, hypogynous, small, spinescent, green.
• Flowers are tetra- or pentamerous, with the stamens adnate to the white or pink funnelform or salverform corolla.
• Flowers are hermaphroditic and pentamerous, arranged in corymbs with many heads, about 3 mm in diameter, with rounded ligules.
• The flowers are often closely clustered (fascicled) with the five petals (pentamerous) fused into a tube (gamopetalous).
• Its flowers lack pedicels and are pentamerous and staminate; they have a pistillode with reduced pilosity; glabrous heteromorphic tepals with truncate tips.
• It has staminate flowers on short pedicels that are pentamerous, with a pilose pistillode, plus heteromorphic pilose tepals.
