IB Biology: C3.1-Ripening of Fruits and Ethylene

Front

What changes occur during the ripening of fruits?

Back

Changes in color, softening of the flesh, conversion of acids and sugars into sugar, synthesis of volatile substances or scents.

Front

What stimulates the ripening of fruits?

Back

A gaseous phytohormone called ethylene or ethene, produced by a ripening fruit.

Front

How does ethylene affect nearby fruits?

Back

Exposure to ethylene stimulates more ripening in nearby fruits, promoting the production of more ethylene.

Front

What type of feedback mechanism is involved in the ripening of fruits?

Back

Positive feedback control mechanism, as the release of ethylene leads to more release of ethylene.
