<p>Could someone explain the alternation for me? Are the haploid gamates produced by mitosis and the haploid spores produced by meiosis?</p>
<p>Cliffnotes says, ‘Spores produced by mitosis develop in the capsule.’ so I am really confused.</p>
<p>Basically, there are two life forms of a plant: sporophyte and gametophyte. The diploid sporophyte produces spores via meiosis. These spores mitotically develop into a haploid gameophyte (antheridium is male and archegonium is female). The anteridium produces male gametes, which somehow travel to the inside of the archegonium and join with an ovary to produce a zygote. The zygote will develop into a sporophyte; and the process starts again.</p>
<p>ahhh our teacher never taught us this! can someone explain this with more details? kind of fearing that it will be on the test!</p>
<p>It probably will be on the test. For future reference, if cliffnotes doesn’t help, just use wikipedia:</p>
<p>[Alternation</a> of generations - Wikipedia, the free encyclopedia](<a href=“http://en.wikipedia.org/wiki/Alternation_of_generations]Alternation”>Alternation of generations - Wikipedia)</p>
<p>basically the gametophyte generation = haploid, sporophyte generation = diploid</p>

<p>My teacher has never ever taught us about biodiversity, muscular/immune systems, animal production, animal behaviour and ecology and we’ve done very limited number of labs. I wonder why they still call the course “AP Biology”.
Other courses are even worse…</p>
<p>go get a barrons book and read it. or a cliffnotes one</p>
<p>Cliffsnotes/PR/Barron are my babies. :)</p>
<p>“My teacher has never ever taught us about biodiversity, muscular/immune systems, animal production, animal behaviour and ecology and we’ve done very limited number of labs. I wonder why they still call the course “AP Biology”.”</p>
<p>Don’t worry, my class is the same. We did ecology in two days, and totally skipped a couple of chapters.</p>
<p>I sometimes wish I had enough money to go to a competitive private school. I believe the education quality is way better.</p>
<p>My class didn’t do anything either… barely touched the textbook, and now I will be lucky to get a 4</p>
<p>actually, I’m quite happy with my school. Less competition and better atmosphere :). For everything you don’t learn in school, you can just get a prep book and learn on your own.</p>
<p>@santeria: haha, I’m not worried about bio at this point, but I’m pretty sure I’ll fail mechanics tomorrow :P.</p>
<p>^Yeah I agree. I think I’ve become much more independent.</p>
<p>Gametophytes as in gametes–haploid.</p>
<p>Oh, and bryophytes have the gametophyte as the conspicuous generation. And you know how you can remember?</p>
<p>Because Boys join Gangs</p>
<p>B = bryophytes
G = gametophytes</p>
<p>You can also recognize angiosperms as flowering plants because you can associate “angels” with flowers. Also, angiosperms, gymnosperms, and pteridophytes have the sporophyte generation as their conspicuous.</p>
