Unit 2 Labs: Exploring Plants and Flower Dissection
Lab #2: Exploring Plants
Problem: How are plants adapted for different environments?
Hypothesis: Write in an if…then…format
Materials: outdoor space
Method:
Part A: Plant Walk and Observations
Go on a walk…around your yard, neighborhood, a local park…observe at least 5 kinds of plants. If possible, name them using an identification key.
Fill in the table in the results section as you make your observations. Make at least 2 drawings as well.
Part B: Parts of Plant
Learn about different parts of plants in Supermarket Botany.
First learn about the plants and the parts they are made of.
Then take the challenge. Choose 6 different plant parts to learn about and complete the chart in the results for part B.
Results:
Part A: Plant Walk and Observations
Name of Plant
Describe the Stem
Describe the leaves
Describe the
seeds (if present)
Describe the flowers (if present)
Plant 1
Plant 2
Plant 3
Plant 4
Plant 5
Part B: Parts of a Plant (from Supermarket Biology)
Plant Name
Plant Part?
Explain why it’s that part
Discussion/Analysis:
Describe the environment you walked through on your plant walk. How were the plants you noticed adapted to this environment?
How are the plant parts similar? How were they different?
Describe how roots, stems, and leaves are adapted for their various functions in the plant.
If a plant is aquatic what adaptions might it have to its environment?
Conclusion: Answer the problem question. Was your hypothesis correct? Was there anything you didn’t understand?
Lab #3: Flower Dissection
Problem: How are plants adapted for reproduction?
Hypothesis: Write in an if…then…format
Materials: flower, knife
Method:
Obtain a flower that you can dissect. Good choices include lilies, tulips, and daffodils.
Draw and label the whole flower.
Lay the flower on a cutting surface. Using a knife (be careful!), cut the flower in half. You will cut through the petals and the ovary.
Draw a cross-section (one of the halves) and label the major parts you observe.
Results: please note I want to see a drawing you’ve done for this part. Use section 2.3 to help you label.
1. Drawing of entire flower with labeled parts
2. Drawing of cross-section with labeled parts
Discussion/Analysis:
If a flower is pollinated by the wind, what would you expect it to look like? Would it be large or small? Have bright colors? Etc.
If a flower is pollinated by an insect, what would you expect it to look like? Would it be large or small? Have bright colors? Etc.
What adaptations do flowers have to protect the ovules and pollen?
Conclusion: Answer the problem question. Was your hypothesis correct? Was there anything you didn’t understand?
