Microscope Slides 1. Examine a prepared slide of a longitudinal section through a mature pine pollen cone. Label a pollen sac in Figure 15.7a and a pollen grain in Figure 15.7b. A pollen grain has a central body and two attached hollow bladders. How do these help in the dispersal of pine pollen? One pollen grain cell will divide to...

1. When you look at a pine or maple tree, the plant you see is a _____. 2. The Brazil nut tree, Bertholletia excels (n = 17), is native to tropical rain forests of South America. It is a hardwood tree that can grow to over 50 meters tall, is a source of high-quality lumber, and is a favorite nesting site for harpy eagles. As the rainy season ends, tough-walled fruits, each containing 8-25 seeds (Brazil nuts), fall to the...
