Materials:
- flower
- colored pencils
- tweezers
- magnifying glass (optional)
Procedure:
- Locate the outermost layer of flower parts. These are the sepals. Draw and label the sepals to begin your flower diagram.
- Carefully remove the sepals.
- Petals form the next layer of flower parts. Draw and label the petals in your drawing.
- Carefully remove each petal.
- Stamens - the male flower parts should now be exposed. Add the stamens to your drawing and label them.
- Carefully remove the stamens.
- Only the female flower parts should remain. Add the pistil to your drawing. Label the pistil, stigma, style, and ovary
Analysis Questions:
- Write the function of the following structures next to their labels in your drawing:
- sepals
- petals
- anther
- filament
- stigma
- style
- ovary
- Do flowers usually contain more stamen or pistils? Support your answer.
- What does the position of the anthers relative to the position of the stigmas suggest about how this flower is pollinated?
