Mosses and Ferns
Sections 3.2
Mosses
• One of the first types of plants to live on land• Have a thick cell wall• Special storage area for water and nutrients
Mosses
• Do not grow large• Have simple structures that function like roots, stems
and leaves
• Nonvascular – No vascular tissue (xylem, phloem)
• Bryophyta
Moss Reproduction
• First generation grew from spores
• Wind carries spores away from parent
• Within a clump of moss are male and female reproductive structures

Moss Reproduction
• When water is present sperm can swim to egg to fertilize
• Second generation grows into spore producing plant
Moss Reproduction
• Also able to reproduce asexually–Broken pieces can form new plant–New plants can branch from old ones–Allows for quick growth
Ferns
• Vascular plants• Able to grow tall• Have true leaves, stems and roots• Tracheophyta
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
