FRUIT. FRUIT FUNCTION FRUIT ORIGIN (I): OVARY.

Fruit. Most people think of fruit as something fresh from the market, or canned or frozen, to which you may want to add sugar before eating. However,

FRUITS Fruits can be divided into three categories: 1. Simple fruit

Definition: the fruit is the whole product of the development of the gynaecium as a result of fertilization. Sometimes other parts of the flower in addition.

FRUIT. Fruit Functions Fruit = mature, ripened ovary 1.Prevent the seeds from drying 2.Disperse the seeds May be either fleshy or dry.

From Flowers to Fruits How did that happen? Let’s find out!

HORTICULTURE.  When you think of fruit you typically think of a juicy edible object, such as an apple, orange or banana. However fruit includes many.

Pollination Occurs when pollen reaches the stigma

F r u i t

1. Pear = Simple (fruit develops from single,ripened ovary) fleshy/Pome 2. Strawberry = aggregate (fruit develops from many small ovaries within a single flower) Green leaflike structure = sepal Seeds found= outside on receptacle inside seed (achene)

3. Maple= Simple/Dry/ Indehiscent/ Samara 4. Olive= Simple/Fleshy/Drupe 5. Pea Pod= Simple/Dry/Dehiscent/Legume(Pod)

6. Sunflower= Simple/Dry/Indehiscent Achene 7. Tomato = Simple/Fleshy/Berry How many locules are in this sample? 7 8. Grape = Simple/Fleshy/berry

9. MILKWEED = Simple/dry/Dehiscent/ Capsule 10. ACORN = Simple/dry/ Indehiscent/nut Ovary ( thick hard wall) Cup like structure is made of modified leaves.

11. Coconut= Simple/Fleshy/DRUPE White of coconut: Endosperm (food for embryo) Embryo behind the 3rd soft eye.

12. PINEAPPLE MULTIPLE How many flowers are in section of fruit? 12

13. KERNAL OF CORN (Corn on the Cob) Simple/Dry/Indehiscent/Grain What is the function of the silk? Female—long stigmas.

14. ORANGE Simple/ fleshy/Berry 15. Avocado Simple/fleshy/Drupe 16. Banana Simple/fleshy/Berry What causes the browning on the banana? Ethylene gas

17. APPLE= Simple/fleshy/Pome 18. PAPAYA = Simple/fleshy/Berry

SPIKE FRUIT = berry Cactus Pear = berry Starfruit = berry

FIG= Multiple fruit Synconium  seed is an Achene Peach = Pome Lemon = Berry Lime= Berry Grapefruit= Berry

Cantaloupe= Berry Honeydew= Berry Watermelon = Berry Kiwi= Berry Blueberry= berry Cucumber = Berry

Peanut = legume(Pod) Raspberry = Aggregate Mango = Pome Pecan = Nut

S e e d s A “packaged“ plant . Contains the plant embryo & nourishment for the new plant .

Analysis: 1.Formation of fruit/seed in a simple fruit After fertilization the OVARY wall develops 3 layers (endocarp, mesocarp, exocarp) Exocarp  enlarge become fleshy or dry fruit OVULE  SEED Receptacle can be fruit

2. Fruits where seeds are eaten are: Sunflower, beans, peas, peanuts 3. Distinguish the fruit from other parts of the flower by: Fruit has one or more ovaries with a seed or seeds. 4. An aggregate fruit differs from a multiple fruit by: Aggregate  fruit with many ovaries in a single flower Multiple  many flowers

5. An aggregate fruit is similar to a multiple fruit by: Both develop specialized tissue in addition to the ovary.
