Simple Fruits : one fruit that has developed                  used by all living things.
from the ovary of a single flower. Simple
fruits may either be fleshy, like plums and
peaches, or dry, such as walnuts and hazelnuts.
e.g. apples, pears, plums, tomatoes, peaches
Aggregate Fruits : a fruit formed from
several ovaries of one flower that produces
many tiny fruits clustered tightly together. e.g.
raspberries, blackberries, strawberries
Multiple Fruits : a fruit formed from the
fusion of the ovaries of many different flowers
which develop closely together to form one
bigger fruit. e.g. pineapples, figs, breadfruit,
mulberries
