Flower Dissection — Part 2

Pick a flower from your yard, a public location, or somewhere in your neighborhood.
Start by removing the sepals of the flower with a tweezer. If you do not have a tweezer, a small pair of scissors will also work. It may be easiest to do this if you hold the flower with your finger from below the pedicel (small stalk just underneath the flower) and begin to remove the sepals with a pair of tweezers.
Using tweezers, place the sepals on the labelled printable worksheet, and tape them in place.
Repeat the same procedure for the petals and pistil.
Remove all but one of the stamens and tape them onto the worksheet.
On your printable worksheet, you should have sepals, petals, stamens and one pistil.
Take a picture of your worksheet with the flower pieces placed correctly, and save it on your computer. You will attach and submit this with your assessment questions.

Plant Tissues

What are three characteristics that all species belonging to the plant kingdom have in common?
How will the numbers of stomata differ in tropical plants and desert plants? How does this help protect the health of a plant?

Why do we compare the dermal tissue of plants to human skin? Explain your answer.
Would a plant be able to survive if the ground tissue was damaged? Explain your answer.

Flowering Reproduction

Describe how flowering plants reproduce.
How do flowers help other organisms in our environment?
Which parts of a plant are responsible for reproduction? Describe the role that each of them will play.
Describe what occurs during the process of seed development.
