Final answer:
An accessory fruit is a fruit that develops from tissues other than the ovary. Examples include strawberries, apples, and pears.
Step-by-step explanation:
Fruits that develop from tissues other than the ovary are known as accessory fruits. These fruits are not derived from the ovary but from another part of the flower, such as the receptacle or the hypanthium. Examples of accessory fruits include strawberries, which develop from both the ovary and the receptacle, and apples and pears, which develop from the ovary and the hypanthium.
