while a bulb is a modified belowground storage organ
A plant or a vegetal is made of different parts:
root, stalk or stems, leaves, flowers and fruits
Not all need to be present at all plants and some
have different types.
The stem holds and maintains the leaves, flowers
and fruits. Through it a juice circulates with all
minerals that allows life for the plant.
A bulb is a type of stem that grows subterraneous,
toward the inside of earth, it is generally bulky
and contains nutricious substances as a reserve.
Like onion for example.
The root mostly the time is also subterraneous and
has
2 important functions: it fixes and holds the plant at
the earth and absorbs water and minerals from the
soil
that are needed for its life.
