Fruit, False Fruit and Seedless Fruits (Leaving Cert Biology): Flashcards

After fertilisation

Enlarges to protect and nourish seeds

Seeds

Growth regulators (auxins) from seeds

Swell with water and food (e.g., plums, oranges)

Swell with food only (e.g., beans)

Wall of fruit (from ovary wall)

Protect seeds and aid seed dispersal

Apples, pears, strawberries

Receptacle (not ovary)

Seedless fruit formation without fertilisation

Bananas, pineapples

Spraying with growth regulators (auxins, gibberellins)

Removes green colour and ripens fruits

Stops ripening, allows long-term storage
