Land plants

evolved from one lineage of charophyte algae after formation of ozone layer had made life on land possible

• 1. Byrophytes
• land plants
• seedless
• 2. Seedless vascular plants
• 3. Gymnosperms---seeds
• 4. Agiosperms --- flowering

• early--> gametophyte-> dominant -> diploid
• Present--> Sporophyte-> dominant-> Haploid

• body thallus
• chromosome state - haploid
• gemmae cups produce asexual gemmae (small pieces of plants)
• male and female plants are gametophytes because they eggs and sperm

• Gametophytes
• haploids
• go through mitosis to produce egg and sperm
