Abstract

Hands-on experimentation with polyploidy is a useful approach to connect research with classroom teaching. The following activity uses marigolds to explore the effects of differing chromosome number on plant cell size. Researchers have documented a correlation between plant ploidy and guard cell size, and its correlate, density (Masterson 1994). Guard cells control opening and closing of stomates on the leaf surface.
