Part 1: Gymnosperms
1. Draw a Cedar Leaf and Pine Needle.
a. What conditions are these two types of leaves adapted for? Describe the size and
shape of the two types of gymnosperm leaves
2. Draw an Ovulate Cone and a Single Sporophyll.
a. How many seeds on each scale?
3. Draw a Pollen Cone and some Pollen Grains.
Part 2: Angiosperms
1. Describe any differences you observe on the upper and lower surfaces on an angiosperm leaf.
2. Sketch an Anther and Pollen Grains.
3. Sketch the Pistil and label the Ovule and Ovary.
Questions
1. Why is the female cone larger than the male cone?
2. A student has two slides, one of pollen grains and one of fern spores. Using your observations and
sketches from this lab, describe how the student could determine if the slides contained gymnosperm
pollen, angiosperm pollen, or fern spores?
3. Why does the gymnosperm pollen have “wings”? Why didn’t the angiosperm pollen have wings?
