Life Cycle Of Gymnosperms

Gymnosperms, which translates to "naked seeds," are a diverse group of seed plants. The angiosperms are a sister group to one group of gymnosperms (the Gnetales), making the gymnosperms a paraphyletic group, according to the "anthophyte" hypothesis. The …

Life Cycle Of Pteridophytes

They are the first land plants with vascular tissues (xylem and phloem). These vascular plants are classified as vascular cryptogams because they do not contain flowers or seeds. These plants are the most common and visible group of land plants, accounti…

Life Cycle Of Angiosperms
