Peace
13:3 And it is He who spread the earth and placed therein firmly set mountains and rivers; and
from all of the fruits He made therein two mates; He causes the night to cover the day. Indeed in
that are signs for a people who give thought.
The verse speaks of pollination or the continuance of the fruit species.Some monoecious fruit tree flowers are often referred to as "perfect" flowers, meaning both the
female and male parts are contained in the same flower. Others monoecious fruit trees have
separate male and female flowers but on the same tree.
Some types of fruit trees require two trees to insure a fruit crop -- but not all do. Flowering plants,
including fruit trees, require pollination before fruit is produced. When pollen, the male contribution,
finds its way to the female structure, fertilization occurs and a fruit is born. Whether or not two trees
are needed depends on whether the plant produces both male and female flowers or only one of the two.
