deep in the tropical rain forest, a botanist discvoered an unusual plant with vascular tissurs, stomata, a cuticle, flagelleated sperm, conelike reproductive tructures bearings seeds, and an alternation-of-generation cycle. he was very excited baotu this discovery becasue it would be rather unusaul for a plant to hav both
