• Gamatangia
• ? gametes ( and -)
• ? zygote (Often the only diploid form)
• ? spores (haploid)
• ASEXUAL
• Break apart and continue to grow
• Sporangia
• ? spores

7
Vocabulary

• Diploid (2N)
• Two complete sets of chromosomes
• Haploid (N)
• One set of chromosomes

8
Spreading Their Domain

• Weightless spores
• Very light, wind borne
• Numerous spores (millions)
• Large numbers increases success
• Animal attraction
