MODULE 5 L2: FRUITS AND SEEDS Flashcards
a characteristic of flowering plants. Once pollination and fertilization occur, the ovary of the plant becomes the fruit and the ovules become the seeds.
FRUIT
They can be fleshy or dry
FRUITS
Main purpose is that they protect the seeds during
development.
FRUITS
often colorful and emanate a delectable odor, they help in attracting birds and other animals to eat seeds. This way the seeds get dispersed to other areas for generating new plants.
FRUITS
FRUIT REGIONS
- The skin
EXOCARP
FRUIT REGION
- The inner boundary around seed(s)
ENDOCARP
FRUIT REGION
- The tissue between exocarp and endocarp
MESOCARP
3 regions is collectively called
PERICARP
CLASSIFICATION OF FRUITS
- one fruit that has developed from one single flower
SIMPLE FRUIT
CLASSIFICATION OF FRUITS
- one flower that produces tiny fruits clustered tightly together
AGGREGATE FRUIT
CLASSIFICATION OF FRUITS
- fruits from many different flowers which develop closely together to form one bigger fruit

PERICARP
- EXOCARP
- MESOCARP
- ENDOCARP
BASED ON THE ORIGIN
- Fruit that develops after fertilization
NORMAL
BASED ON THE ORIGIN
- Fruit that develops without fertilization
PARTHENOCARPIC
BASED ON THE NUMBER OF OVARIES INVOLVED IN ITS FORMATION
- Developed from one ovary
SIMPLE FRUIT
BASED ON THE NUMBER OF OVARIES INVOLVED IN ITS FORMATION
- Develops from several ovaries
COMPOUND FRUIT
BASED ON THE NUMBER OF OVARIES INVOLVED IN ITS FORMATION
Types of Compound fruit
AGGREGATE AND MULTIPLE
BASED ON THE NUMBER OF OVARIES INVOLVED IN ITS FORMATION
Types of Compound fruit
- Develops from several ovaries of a single flower
AGGREGATE
BASED ON THE NUMBER OF OVARIES INVOLVED IN ITS FORMATION
Types of Compound fruit
- Develops from several ovaries of a compact inflorescence
MULTIPLE (collective)
Example of Aggregate fruit
ATIS (Annona squamosa)
Example of Multiple fruit
PINEAPPLE (Ananas comosus)
BASED ON CONSISTENCY
- Legume of Pod
- Follicle
- Capsule
- Silique
PERICARP DRY AND DEHISCENT
BASED ON CONSISTENCY
PERICARP DRY AND DEHISCENT
- Arises from a single carpel which maturity splits along two sutures
- With the shell, pericarp enclosing the seeds
Ex. Peanut, sitao, batao, patani
LEGUME OR POD
BASED ON CONSISTENCY
PERICARP DRY AND DEHISCENT
- Develops from single carpel and opens along one suture
Ex. Camachile
FOLLICLE
BASED ON CONSISTENCY
PERICARP DRY AND DEHISCENT
- Derives from an ovary with 2 or more united carpels, each carpel producing few to many seeds and splits in various ways.
Ex. Banaba, okra, cotton
CAPSULE
BASED ON CONSISTENCY
PERICARP DRY AND DEHISCENT
- Derived from superior ovary consisting of two locules which at maturity separates into three portions with the seeds attached to the central, persistent portion
Ex. Malunggay
SILIQUE
BASED ON CONSISTENCY
- Achene
- Grain (Caryopsis)
- Samara
- Schizocarp
- Nut
PERICARP DRY AND INDEHISCENT
BASED ON CONSISTENCY
PERICARP DRY AND INDEHISCENT
- Commonly called ‘seeds’ buy when the pericarp is broken, the seeds within is seen to be attached to the ovary wall at one point.
Ex. Sunflower
ACHENE
BASED ON CONSISTENCY
PERICARP DRY AND INDEHISCENT
- Like the achene, it is also one seeded, but the pericarp and seed coat are firmly united.
Ex. Corn, Rice
GRAIN (caryopsis)
BASED ON CONSISTENCY
PERICARP DRY AND INDEHISCENT
- May be one-seeded or two-seeded and has wing like outgrowth of the ovary wall.
Ex. Narra, Maple
SAMARA
BASED ON CONSISTENCY
PERICARP DRY AND INDEHISCENT
- Derived from 2 carpels which splits when mature
Ex. Mustard family
SCHIZOCARP
BASED ON CONSISTENCY
PERICARP DRY AND INDEHISCENT
- One seeded fruit with a hard or stony pericarp commonly called the “shell”.
Ex. Cashew, Pistachio, Walnut, Chestnut
NUTS
BASED ON CONSISTENCY
- Berry
- Hesperidium
- Pepo
- Drupe
- Pome
PERICARP FLESHY
BASED ON CONSISTENCY
PERICARP FLESHY
- The pericarp is soft and fleshy
- Usually many seed are embedded in a fleshy part which is both endocarp and mesocarp
Ex. Eggplant, Tomato, Grapes
BERRY
BASED ON CONSISTENCY
PERICARP FLESHY
- Type of berry with a thick, leathery exocarp, and with thick juicy mesocarp.
Ex. Orange, Dalandan, Calamansi
HESPERIDIUM
BASED ON CONSISTENCY
PERICARP FLESHY
- Berry-like fruit with hard exocarp while the fleshy part of the fruit is principally mesocarp and endocarp.
Ex. Watermelon, Cucumber
PEPO
BASED ON CONSISTENCY
PERICARP FLESHY
- Usually ine seeded, exocarp is thin, mesocarp may be fleshy or fibrous and the endocarp is hard.
Ex. Coconut, Mango, Avocado
DRUPE
BASED ON CONSISTENCY
PERICARP FLESHY
- With thin, papery exocarp
- Derived from an inferior ovary, the fleshy part is the enlarged floral tube and the core comes from the ovary.
Ex. Apple, Pear
POME
This accessory ‘fruit’ is actually an enlarged receptacle
STRAWBERRY
Embryotic plants enclosed in a protective outer covering.
