Water vs Land
Algae – mainly aquatic
Moss – damp, shady locations
What challenges do plants have to overcome to live on land?
Non-vascular plants (no pipes)
Transport water by osmosis
Found in moist shady areas
One cell thick leaves;
lack cuticle = more evaporation
Rhizoids – anchor to ground
Rhizome – underground stem
Lack true roots, do not play a major role in absorption
3 Main types
Class Musci: true moss
Male and female usually separate
Similar to algae
Water transports sperm to egg in moist environment
What are the three groups of bryophytes?
Algae live mainly in the water and mosses live on land. What features do mosses have that have allowed them to do this?
What features do more complex land dwelling plants have that mosses lack?
Are the gametes of bryophytes haploid or diploid? Are the spores of bryophytes haploid or diploid?
Describe the life cycle of a moss. You can draw a labelled diagram if you want.
Is the dominant part of the mosses life cycle spent as a sporophyte or gametophyte?
