In mosses gametes are produced by _____; in ferns gametes are produced by _____.
answer
mitosis ... mitosis
question
Bryophyte structure
Bryophyte structure
answer
Part A: sporophyte (seta + sporangium) Part B: seta (just the stem) Part C: sporangium (the weird bulb thing at the top) Part D: foot (base of the stem) Part E: gametophyte (the green fernish bits) Part F: rhizoid (it's just the fricckin roots)
question
Life cycle of mosses
answer
1: Mature sporophytes produce haploid spores, dispersed by the wind 2: Separate spores into female and male gametophytes 3:Haploid eggs form in archegonia, and haploid sperm form in antheridia 4: Haploid gametes undergo fertilization, forming a diploid zygote 5: The diploid zygote develops into a sporophyte

answer
a sporophyte
