  1. Mosses and Ferns Sections 3.2

  2. Mosses • One of the first types of plants to live on land • Have a thick cell wall • Special storage area for water and nutrients

  3. Mosses • Do not grow large • Have simple structures that function like roots, stems and leaves • Nonvascular – No vascular tissue (xylem, phloem) • Bryophyta

  4. Moss Reproduction • First generation grew from spores • Wind carries spores away from parent • Within a clump of moss are male and female reproductive structures Start here

  5. Moss Reproduction • When water is present sperm can swim to egg to fertilize • Second generation grows into spore producing plant

  6. Moss Reproduction • Also able to reproduce asexually • Broken pieces can form new plant • New plants can branch from old ones • Allows for quick growth

  7. Ferns • Vascular plants • Able to grow tall • Have true leaves, stems and roots • Tracheophyta

  8. Fern Reproduction • Spores grow into structures that are low to ground and produce sperm and egg • Water is needed to have sperm fertilize eggs • Fertilized eggs grow into plants with fronds that grow spores
