Lesson 11: sporophytes

Question 1

alternation of generations:

Answer 1

• starts with a haploid gametophyte
• this makes sperm and egg cell using mitosis
• through syngamy, it will form a zygote (diploid)
• this will then form a sporophyte (diploid plant)
• sporangia (diploid) then also make spores through mitosis (haploid)
