Fruit Formation/ Plant Modification Flashcards
These are the layers of the PERICARP.
Exocarp, Mesocarp and Endocarp
OR
Exocarp and Endocarp
This is the thickened ovary which then covers the fruit.
Pericarp
This category of fruit is characterized by fruit that is formed from the SINGLE OVARY of a SINGLE FLOWER.
Simple Fruit
This category of fruit is characterized by fruit that is formed from MANY fused OVARIES of a SINGLE FLOWER.
Aggregate Fruit
This category of fruit is characterized by fruit formed from MANY fused OVARIES of a CLUSTER OF FLOWERS.
Multiple fruit
This is a subcategory of fruit that SPLITS open.
Dehiscent
This is the type of DRY DEHISCENT fruit that SPLITS open along ONE SIDE.
Follicle
This is a type of DRY DEHISCENT fruit that SPLITS open along TWO SIDES.
Legume
This is a type of DRY DEHISCENT fruit that contains TWO OR MORE CHAMBERS and SPLITS open along MORE THAN TWO SIDES.
Capsule
This is a subcategory of fruit that DOES NOT SPLIT open
Indehiscent
This DRY INDEHISCENT fruit has a very HARD OVARY WALL.
Nut
This is an DRY INDEHISCENT fruit with a WING-LIKE OUTGROWTH.
Samara
This is a DRY fruit where the seed is COMPLETELY ATTACHED at only ONE PLACE inside ovary wall.
Achene
This is a DRY INDEHISCENT fruit where the seed is completely attached the the ovary wall so that the two CANNOT BE SEPARATED.
Grain
This is a FLESHY fruit containing only ONE SEED located inside (PIT).
Drupe
This is a FLESHY fruit containing SEVERAL SEEDS, has a FIRM LEATHERY RIND and has NO SECTIONS.
Pepo
This is a FLESHY fruit with a LEATHERY RIND and MANY SECTIONS and the RIND IS SEPARABLE.
Hesperidium
This is a FLESHY fruit that has an EDIBLE PEEL that is NOT LEATHERY and has a CORE.
Pome
This fruit is more or less FLESHY throughout and the SEEDS ARE EDIBLE.
Berry
This is a STEM MODIFICATION where HORIZONTAL STEMS grow AT or BELOW soil surface. It can act as a STORAGE ORGAN.
Rhizome
This is a RHIZOME that becomes ENLARGED for FOOD STORAGE.
Tuber
This is a VERTICAL UNDERGROUND SHOOT, consisting of enlarged bases of LEAVES that STORE FOOD.
Bulb
This is a STEM that are BULB-LIKE in appearance but are MOSTLY STEM TISSUE.
Corm
These are MODIFIED AERIAL STEMS for CLIMBING.
Tendrils
These are CREEPING STEMS that GROW HORIZONTALLY ON the SOIL SURFACE
Runners/Stolons
These are OUTGROWTHS OF the WOOD of a twig.
Thorns
These are sharp EPIDERMAL OUTGROWTHS of the STEM.
Prickles
These are FLATTENED STEMS with a LEAF-LIKE shape.
Cladophylls
This is a LEAF MODIFICATION which PROTECT the plant from predators and shade the plant.
Spines
This LEAF MODIFICATION functions to TRAP INSECTS as a supplemental source of plant nutrition.
Insectivorous
This LEAF MODIFICATION functions like FLOWER PEDALS to ATTRACT POLLINATORS.
Bracts
This is the MIDDLE FLESHY layer of the fruit wall.
Mesocarp
This is the INNER LAYER of a pericarp
Endocarp
This is the OUTERMOST LAYER of the fruit wall.
Exocarp
