 The Parts of a
Flowering Plant |
 Roots
The root is one of the
first parts of a plant that starts to grow. A primary
root develops from a plant's seed and
quickly produces branches called secondary
roots. |
 Stems
make up the largest parts
of some kinds of plants. |
 Leaves
are the main food-making
parts of almost all plants. They capture energy
from sunlight and use it to make food out of
water from the soil and carbon dioxide. This food
provides plants with energy to grow, to produce
flowers and seeds, and to carry on all their
other activities. |
 The Parts of a Leaf
Most leaves have two main
parts: (1) the blade and (2) the petiole, or
leafstalk. The leaves of some kinds of plants
also have a third part, called the stipules. |

stalk. The flower consists of four whorls,
or sets, of parts. These whorls are (1) the
calyx, (2) the corolla, (3) the stamens, and (4)
the pistils. |
 Seed
Parts Seeds consists of three main parts: (1)
the seed coat, (2) the embryo,
and (3) the endosperm. |
