Prokaryotic cells were simple enough, but eukaryotic cells are much more complex! They have so many more little features and compartments, like the deluxe model of your car. We have to learn about every single one of these organelles and other components before we move on to other areas of biology, so let's take a tour of the eukaryotic cell, starting with animal cells!

Wow - Prof Dave explained 30-40 pages of textbook in just 14-15 mins, with enough level of detail to really remember something valuable. Really cool!

@@quinndenver4075 Because as you get older, start working, start studying other courses, things like this are forgotten. Yes we knew this when we were younger, then we forgot it. Also med school moves much faster so this is maybe 1 or 2 days worth of lecture and then move on to other things. So it's a lot of information in a short time

@madisondampier3389 2 года назад

I just need to say, knowing this is how the very basis of intelligent life is organized, is much more profound and spectacular of a perspective on the world than the religious ideology I grew up with. Seeing how everything is explained here is a much richer understanding of the subject than I ever learned at school, the specific functions of every organelle and what they're made of had never been explained to me before, and the teacher was not so fond of actually teaching us the subject, I think she hardly spoke except to tell us what the assignment was. You've filled a lot of the gaps in my knowledge and for that I appreciate this series a lot. Life is so much more complex than people give it credit for, no book could ever be printed containing the full knowledge of the outcomes nature is capable of; not one that could ever be carried around, that is! It's a joy to know a person like you is here to share with anyone what the reality is behind everything around us.

I've been waiting for this video for a long time. Congratulation it's a really complete video. Thanks for investing you time and knowledge with eukaryotes organisms like us. God bless. now my question is, if mitochondrias have their own DNA how do they transfer it during the mitosis of the cell? Can a mitochondria divide itself?

@ProfessorDaveExplains 7 лет назад

i believe it can! i'll have to do a little research

@pramitlahiri1978 6 лет назад

Idk whether mitochondria can divide itself, but it does so during the interphase. At that time, even the DNA within in it divides to form it's clone.

Excellent factory analogy sir. But my greatest doubt from many years is that factory must produce a product and deliver out for a purpose. But cell itself is like a factory that uses it own produced product to live. So my doubt is why should it work? Why should it gather in a place and work to gather to stay alive? There will be a core inbuilt reason for all of their hard work. Please clarify sir. Anyway I love this channel and views a lot of content. My love and graceful respect for providing knowledgeable and needful content sir.

According to endosymbiotic theory billions of years ago some bacteria were photosynthetic some can respire and they then merge resulted in an eukaryotic cell, but my Q is how can an isolated organelle (bacteria) can function independently?

@ProfessorDaveExplains 6 лет назад

it's a very good question! i mean, if an organelle is generating a surplus of ATP, i can see how that could escape its membrane by diffusion and be available to the larger host cell, but as to how they slowly merge to become one organism is unclear to me. how they can function independently is no problem, as they are separate organisms that previously were surviving separately. but i'm sure there is some information out there even if still incomplete!

@comment8767 Год назад

So was there one, original entry event that created the symbiosis? Or did this happen many times. If the latter, it would seem that there should be plural, distinct kinds of mitochondria. But it seems like they all come from the same genetic history. Why would such an event happen only once, or a limited number of times? Same goes for chloroplasts. If a symbiotic event is unique, it would seem to be possible only under very special conditions... perhaps in a laboratory aboard some UFO or the like. If it is an easy process, we should be able to duplicate it in a terrestrial lab. I have not heard of someone doing this.

@ProfessorDaveExplains 4 года назад

No, it doesn't point to anything of the sort. You just believe in god, and are projecting your belief on everything you see.

@DylanBobeck 4 года назад

How so? Just because a cell functions properly doesn't mean it was created. Saying something points to an intelligent creator isn't evidence for said creator. Come back with some legitimate evidence, because I would love to see it.

@Traumbewusstsein 2 года назад

It is astonishing how all this came into being and it is understandable that one infers an intelligent designer because of the sheer complexity, efficiency and beauty of living things. How could something like this possibly evolve without some sort of intention? Yet, we just can't really grasp the time scales of evolution and the possibilities occuring in situations of large numbers. We can only calculate and observe and none of it requires an intelligent designer as a cause.
