Life Cycle Of Bryophytes
A group of plant species that utilize spores, instead of flowers or seeds, for reproduction is known as a bryophyte. The non-vascular seedless plants which include mosses, liverworts, and hornworts are classified as bryophytes. There are over 20,000 spec…
Plant Biometry
Biometry is the science that deals with the statistical investigation of biological observations and phenomena. It is very important in the development of sound and effective agricultural research practices. It is a Greek-derived word wherein 'bio' means…
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…
