UNIT NINE:
BOTANY: STRUCTURE AND FUNCTION OF PLANTS
This unit is the introduction to the
characteristics of the plant kingdom.
Since plants range from algae and moss to large trees, a brief overview
of the different phyla of plants will be done.
Students have already studied the way plants make food and why plants
are important to human life, but they have not been introduced to the specific
structures and functions of the plant kingdom.
The internal structure of plants
will be investigated. In addition, the
reproduction of the plant kingdom will be studied. The exploration of stems, roots and leaves will be included as
part of the structure of plants.
Finally, the growth and development of plants will be studied.
The
following terminology will be used within this unit.
