1. PARTS OF A PLANT

2. Interest Approach
Briefly talk with students about how humans use plants to protect the soil, provide fresh air, and create visual interest. Ask the students if they have thought about plant parts that they eat. As a class, brainstorm edible plant parts. List them either on the chalkboard or on an overhead transparency. After the students have either exhausted their ideas or you think the list is long enough, give each student a copy of WS–A. Have them work in pairs or small groups to identify which category (flowers, fruits, leaves, roots, seeds, or stems) they think each of the foods belong.

3. Student Learning Objectives
1 Identify the parts of a plant.
2 Understand the function of each plant part.
3 Identify the plant parts that are used for
human consumption.

4. There are six main parts of a plant.
Each part is important to the plant’s survival. A. Flower B. Fruit C. Leaf D. Root E. Seed F. Stem

5. OBJECTIVE 2: Understand the function of each plant part.
Each part of the plant has a specific job to do.
Without even one of these parts, the plant, as a whole, would not be able to survive.

6. The Function of Each Plant Part
Flower—The flower is the reproductive organ of the plant that produces seeds.

7. The flower may also attract insects or other animals for pollination, if necessary.

8. B. Fruit
The fruit is the part of the flowering plant that contains the seeds.

9. C. Leaf The leaf is the food factory of the plant.
The leaves use chlorophyll, water, sunlight, and carbon dioxide to make food (sugars) and oxygen.
Photosynthesis!

10. Leaf ANatomy

11. D. Root The root is the anchor of the plant.
The roots also absorb and carry water and nutrients from the soil to the plant.

12. E. SEED
The seed contains an embryo (baby plant) that provides food and water until the plant is able to make food for itself.

13. F. STem The stem holds the leaves and flowers of the plant.
Tubes in the stem transport food and water from the roots to the rest of the plant.

14. OBJECTIVE 3: Identify the plant parts that are used for human consumption.
The fruits, vegetables, and spices that we eat are parts of plants. Many times people incorrectly identify the part of the plant they are eating.
