Fleshy Fruits

What is the difference between the gynoecium and the carpel?: The gynoecium contains all the carpels

What parts make up the carpel?: stigma, style, ovary

Fleshy Fruits

What happens after fertilization?

• Seeds develop into fruit

• What is a fruit → a mature ovary (remeber, it can contain more than one carpel and thus more than on eseed)

• Fruits can be simple or compound. We’ll see some examples from lab.

Fruit types

• Fleshy fruits — all 3 types look similiar from the outside, you have to dissect them to determine what type of fruit you have

  • drupe: have a single hard pit in the center (ex: peach or olive)

    • most common fleshy fruit

    • single hard pit in center

      • Compound drupes

        • can be a multiple or aggregate, of drupes or drupelets (little drupes)

          • Aggregate of drupes: one flower that produces many tiny drupes clustered tightly together, like raspberries and blackberries

        • 

  • berry: are fleshy throughout (blueberry)

    • Berries are fleshy throughout, with small seeds embedded

  • pome (have a papery core (ex: apple)

    • paper core

    • fleshy fruit with thin skin and papery cartilaginous structures enclosing the seeds int he center, often in a star shape

    • flesyy part is swollen receptacle tissue and not an ovary, which is why they are sometimes called “false” fruits

    • ovary is the “core” which has the seeds

    • all pomes are in the Rosaceae family but not all fruits in Rosaceae are pomes)
