modified leaves
modified for storage
stamen
made up of anther and filament, produces male gametophytes
carpel
made up of stigma, style, and ovary, produces female gametophytes
anther
makes pollen
filament
holds anther up
stigma
sticky tip that receives pollen
style
slender stalk
ovary
enlarged structure at base of carpel
sepal
outermost part of flower, protects petals
petals
attract pollinators
calyx
all sepals together
receptacle
connects all parts of flower
fruit
mature ovary containing seeds
pericarp
thickened ovary walls
exocarp
outside
mesocarp
middle
endocarp
inside
simple fruit
develop from a single flower that contains a single carpel or several carpels that are fused together
aggregate fruit
develops from single flower that contains many separate carpels
fleshy fruit
all or most of ovary wall is soft or fleshy at maturity
berry
entire pericarp is fleshy, there may be one or many seeds (grape, tomato, avocado)
pepo
modified berry with hard, thick rind (watermelon, pumpkin, squash)
hesperidium
modified berry with leathery rind and parchment like partitions between sections (orange, lemon, grapefruit)
drupe
