Procedure X-2-5: Observing Reproductive Structures

In this procedure, we’ll dissect and examine the reproductive structures of angiosperms: flowers, fruits, and seeds. Flowers are the primary reproductive structures. Flowers are hugely diverse in shape, color, size, and other characteristics, but all produce the fruits and seeds from which new plants originate.

It’s useful to have a wide selection of live flower, fruit, and seed specimens available. Here are some good choices for each:

Flowers

Any live flower can be used for dissection, but it’s easier to work with flowers whose internal structures are relatively large. (Flowers like carnations and daisies, despite their large petals, have small internal structures.) Gladioli are a good choice, as are azaleas, daffodils, lilies, roses, or tulips. You can find suitable specimens at a florist, the supermarket, or perhaps in your yard.
