Paul Andersen explains how the cell cycle is used to create new cells. The creation of identical diploid daughter cells, through mitosis, is described. The creation of unique haploid daughter cells, through meiosis is also described. ...

Parrots have different parts than humans. Some of their parts look pretty weird to us, so if something on your parrot is tripping you up and you don't know if it's normal, this video is for you. Also, you can just watch for all the cute...

Hank gets down to the nitty gritty about meiosis, the special type of cell division that is necessary for sexual reproduction in eukaryotic organisms.

Ever wonder why we aren’t exact clones of our parents, or why siblings aren’t exactly alike? The reason traces back to meiosis. In this episode of Crash Course Biology, we’ll discover how egg and sperm cells get made and learn why you’re...

What’s the life of a cell like? In this episode of Crash Course Biology, we’ll follow a cell’s life cycle, from its beginning as a shiny new cell all the way to division via mitosis. We’ll learn how our cells control this process, and...

Discover how Dobson uses a childhood memory of meeting an old man to explore human connections.

An old man and a child gaze out over the landscape. A morning mist has spread out over the hills. The two individuals never talk – they...

Explore the processes of cell division and reproduction in animals and plants. Learn about mitosis, the process by which cells replicate and repair damaged tissue, and meiosis, the method of cell division involved in sexual...
