know that apple trees do not "breed true"? This means that if
you plant seeds from an apple, say a Granny Smith, you will get
apple trees, but they will make apples that are actually
different than Granny Smiths. So how do farmers produce new
Granny Smith trees? They use a method called vegetative
propagation. For instance, they may cut a branch off of a tree
that grows Granny Smith apples and attach the branch onto a
different tree trunk. This method of making new trees is called
vegetative, or asexual propagation because the tree was not
produced by the usual mixing of pollen (male) and ovule (female)
to form a seed. In this plant biology science fair project, you
will investigate the factors that influence the success of
vegetative propagation, using the popular spider plant.   The
