Simple fruits - these result from the ripening of an ovary in a flower with only one pistil. They can be fleshy e.g., orange, tomato, gooseberry, and cherry, or they can be hard and dry e.g., nuts such as walnuts, hazelnuts, and oak acorns.

Aggregate fruits - these result from the ripening of an ovary in a single flower with numerous pistils. Each pistil forms a fruitlet, and collectively the fruitlets form a larger fruit e.g., the raspberry, the blackberry, and the strawberry.

 

 

 
Multiple fruits - these are formed from a cluster of flowers on a plant. Each flower produces a fruit, but these mature into a single mass e.g., pineapples, mulberries, and breadfruit.

Vegetables or Fruits?

We think of these as being vegetables.
Contrary to this conventional thinking, these are all ripened ovaries and are
really fruits-the products of fertilization.
If it grows from a flower, it's a fruit!
