These flowers have hairs associated with their stamens which consist of filaments of cells. These cells are ideal for studying the plant cell because they are not embedded in a tissue and because they lack chloroplasts, and, hence, it is easier to observe the ultrastructure of the cell. Students should clearly discern, the cell wall, cytoplasm, the nucleus, the location of the vacuolar membrane (the tonoplast), cytoplasmic threads transversing the vacuole, and also observe the phenomenon of cytoplasmic streaming.
