Fruit Flashcards
(33 cards)
Three types of seed dispersal
Water
Wind
Animal
Carpel
modified leaf tissue;
sepal, petals, and pistil remnants
Locule
space inside carpel where seeds develop
Pericarp
ovary wall;
collection of carpels that form ovary structure
Placenta
tissue that seed is attached to
Two places placenta originates from
basal (bottom)
apical (top)
Four ways egg attaches to placenta
marginal
axile
parietal
free-central
marginal
eggs on outside edge of ovary wall
pariatal
same as marginal but more than one carpal
axile
eggs attached to inside of locule
free central
placenta grows into finger with ovules attached up and down
basal
placenta originates from pedicel
apical
placenta attaches at top of ovary
endocarp
tissue closest to seed
mesocarp
edible tissue
exocarp
skin of fruit
Fruit
seed bearing tissue
Pomes
fleshy fruits with several seed chambers that develop from compound pistils
apples, pears
Berries
many seeded fruits embedded in pulpy body
blueberry, tomato, grape
Pepo
Berry with a hard outer rind
squash, watermelon
Aggregate
fleshy fruit from compound pistils, but one unit, drupelet
raspberry, blackberry, thimbleberry
Drupe
One seeded fruit with hard inner wall and soft outer wall
Peach, apricot, plum, olives, cherries
Compound fruit types
pomes and aggregates
Simple fruit types
Berries and drupes
