Study Notes
Fruit Functions and Types
- The main function of a fruit is to protect and disperse seeds.
Fruit Scars
- Fruits typically have two scars: the stem end (hilum) and the blossom end (stigma).
True Fruits
- A fruit is considered a true fruit if it develops from the ovary of a flower.
Composite Fruits
- A composite fruit is formed from multiple ovaries in a single flower, which merge to form a single fruit.
Fruit Development
- Fertilization leads to the development of the gynoecium, resulting in fruit formation.
Multiple Fruitlets
- When the ovaries increase in size and become aggregated together after fertilization, a fruit type called an aggregate fruit is formed.
Dehiscent Fruits
- Dehiscent fruits are characterized by a dry pericarp that remains attached to the plant, splitting when ripe to release the seeds.
Drupes
- A drupe is a fruit type formed from an ovary with a hard and woody endocarp, fleshy mesocarp, and leathery epicarp, enclosing one seed.
Schizocarps
- Schizocarps are fruits that split up into a number of one-seeded, indehiscent parts called mericarps upon ripening.
Berries
- Berries are fruits that are usually many-seeded and have one or more carpels with entirely fleshy pericarp.
