Plant Structure and Function
NGSSS:
SC.912.L.14.7 Relate the structure of each of the major plant organs and tissues to
physiological processes. (AA)
Purpose of Lab/Activity:
Students will identify the parts of a plant
Students will be able to relate the structure of plant parts to their function
Prerequisite: Prior to this activity, the student should be able to
Identify parts of a plant and their functions
Materials (individual or per group):
Tea leaves or tea bag (Leaf
One fruit (any kind) (Flower)
Celery plant (Stem and Leaf)
Carrot or onion (Root)
Live green plant (in a pot)
If possible, a leaf sample from an ―Oyster‖ plant (Tradescantia discolor)

What the teacher will do:
a. Prepare materials and display them to the whole class.
b. Engage student prior knowledge and understanding by asking the following
questions:
1. What do all these items have in common
2. What are the basic parts of a plant
3. Where do plants come from
What the teacher will do:
a. Display the green plant
1. Ask students to identify parts of the plant.
2. After identifying the parts of the plant ask students to describe the order
in which the plant will grow starting with the seeds.
3. As students describe the growth of a plant, draw or show pictures of
each part.
b. Engage students in a discussion on the function of each of the following
parts of the plant: Roots, Stems, Leaves, and Flowers.
c. Have students make a table on the structure and function of each part
discussed, providing sufficient examples and descriptions.
What the teacher will do:
a. Assess student understanding of plant structure and function by reviewing
its different parts.
b. For additional reinforcement on the concept of plant structure and function
provide students with the handouts on Major Plant Organs and Functions.
