Morphoanatomy of Fruits Flashcards
Any structure that develops from a fertilized ovary and contains seeds of the plant
fruit
the ovary wall becomes the
pericarp
the thickened wall of the
fruit.
pericarp
the fruit develops from a single ovary or the fused ovaries of one flower
simple fruit
develops from several ovaries of
a single flower . Each carpel is separated from one another, therefore it forms a fruitlet.
aggregate
derived from several ovaries of several flowers or from the ovaries of a compact inflorescence.
multiple
used to refer to fruits containing only ovarian tissue
true fruit
a fruit in which some of the flesh is derived not from the floral ovary but from some adjacent tissue
exterior to the carpel
accessory fruit
when the pericarp is soft, juicy (pulpy) or succulent
fleshy
when the pericarp is dry or paper upon maturity
dry
types of simple fleshy fruit
drupe
berry
pepo
hespiridium
pome
fruits with a stony and inedible endocarp
drupes
fruit usually with a fleshy mesocarp and a single seed enclosed in a hard stony endocarp or pit
drupe
all 3 layers of pericarp are soft or fleshy
berry
fleshy fruit with thin skin has few to many seeds
true berries
a berry with hard exocarp
pepo
a berry with a tough skin (rind) that is derived from accessory tissue and the ovary’s exocarp
pepo
berry with a leathery exocarp containing citrus oil
hespiridium
berry-like with leathery or papery endocarp and fleshy accessory tissue derived from the floral tube
pome
the pericarp forms a papery core that surrounds the seeds
pome
types of dry simple fruits
dehiscent fruits
indehiscent fruits
do nit split open to release seeds at maturity
indehiscent fruit
types of indehiscent fruits
samara
achene
nut
grain
schizocarp
have wings for wind dispersal
samara
single-seeded with the seed attached at a single point inside the fruit
achene
hard pericarp from a compound pistil but develops single, unattached seed
nut
pericarp and seed loosely attached
achene
fruit wall fused to the seen coat
grain
at maturity, the compound pistil splits apart into separate carpels called mericarps that fully enclose the seed
schizocarpic
types of simple dry dehiscent fruits
follicle
legume
silique
capsule
dry fruits split open to release seeds at maturity
dehiscent fruits
splits on two sides
legume
splits in several places (one split per carpel)
capsule
splits on one side only
follicle
splitting along one edge only and usually several form per flower to form an
aggregate of achenes
fruit with a compound pistil splitting along or between carpel lines splitting at a number edges lengthwise
capsule
fruit divided from a single flower having several to many pistils
aggregate fruit
derived from several to many separate flowers in an inflorescence
multiple fruit
development of fruit without fertilization.
parthenocarpy
seedless fruits
