FRUITS Flashcards
Dramatic changes in the flower occur after
the union of gametes
results in the embryonic plant
fertilization of the egg
stores food for the embryonic plant and becomes the seed
ovule
becomes mature and changes to the fruit
ovary
develop mechanisms to facilitate seed dispersal
fruits
fruit wall thick and can be differentiated into three layers
pericarp
pericarp three layers
exocarp (outer layer), the mesocarp (the middle layer) and the endocarp (inner layer.)
Fruits can be classified based on its origin:
- Simple fruits
- Aggregate fruits
- Multiple fruits
is derived from a single ovary (consisting of one or several fused carpels) of one flower (ex. Banana)
Simple fruits
originates from one flower with many ovaries (ex. Sugarapple (“atis”))
Aggregate fruits
different types of simple fruits can be further classified according to the texture of the mature pericarp or the fruit wall
A. Fleshy fruits
B. Dry fruits
several flowers of an inflorescence crowded together on one stem (ex. Pineapple)
Multiple fruits
characterized by a dry pericarp at maturity. It can either be dehiscent or indehiscent.
dry fruits
a pulpy fruit throughout from one or more carpels that develops few to many seeds.
Berry
Fleshy fruits
characterized by a succulent fruit wall.
