If plants are cross-pollinated by another species, plants may not grow true to the seed-parent plant. The seeds are close to the skin so avoid cutting to deep. Seedless vascular plants reproduce through unicellular, haploid spores instead of seeds; the lightweight spores allow for easy dispersion in the wind. Chapter 24-Page 10/28.
