Greek words that mean "naked-seeded‚" in reference to the fact that gymnosperm seeds are produced out in the open on cone scales‚ while the seeds of flowering plants are produced completely enclosed within fruits. In the previous lab we learnt that bryophytes and Pteridophytes of the kingdom Plantae‚ reproduce by spores. In gymnosperms and angiosperms (flowerng plants)‚ however‚ dispersal is primarily by means of seeds‚ which are considerably more complex and larger than spores. In contrast to the

This ultimately created a doseresponse experiment in which it was detectable whether or not radish seeds were a reliable bioassay for the toxicity of NaCl.

microwaves positively or adversely affect the growth of grass seeds? This experiment could shed light on the effects of radiation on living things.
