    I don't know why I still go to school, he explains everything better than my teacher

      It is true that the main reason for school vs simply learning on ones own is credentials but that's not the fault of the teachers! i think a lot of the time when people think that folks on youtube explain better than their teacher it is just because on youtube we can pause and rewind! and also because you're actually hearing the information again, even if you didn't understand it the first time to some extent your brain took in a lot of new concepts.🤗

      @@nosleepdelirium1214 agreed; however, the general consensus of individuals when it comes to youtube being "better" than school, teaching wise, is accurate.

  • @CraigSavageScience
    @CraigSavageScience  12 ปีที่แล้ว

    Yes, they are variations of this theme. In mosses the dominant form is the gametophyte (meaning, when you are looking at a moss you are seeing the haploid generation). There is a short lived and dependent sporophyte stage. In ferns the dominant form is the sporophyte (diploid) and there is a short lived (but independent) gametophyte. Once you get to the seed plants (angiosperms and gymnosperms) the gametophyte stage is smaller (pollen and inside the ovule). Check out my fern and moss videos.

    Oh god this was the most helpful thing ever.
    Some of the other videos are good, but they just launch into this long spiel about haploids and diploids and gametophyte, and I'm like what does it all mean ;___;.
    After you explained everything here, it makes much more sense.

    it is said that in bryophytes, the dominant phase in its life cycle is a gametophyte while in a pteridophytes,the dominent phase is a sporophte.......then how come they are examples of haplo-diplontic life cycles where both the generations should have equal dominance in the life cycle of the plant?

  • @juanding9450
    @juanding9450 10 ปีที่แล้ว

    Wonderful lecture! I have a question, if the spore gives rise to gametophyte which can become either sperm or egg, that means the spore has to have gender as well, right? How can you determine if a spore is going to become a sperm or egg in future?

    • @WartsG
      @WartsG 10 ปีที่แล้ว +1

      There isn't just one spore... Spores develop in either the microsporangium (anther) or macrosporangium (ovule) ... These spores then can only divide via mitosis into their respective gametes. hope this helped
