In and out, in and out. Staying alive is about doing things. This very second, your cells are combusting glucose molecules with oxygen to make energy available, which keeps you alive for another precious moment. To get the oxygen to your cells you are breathing.
Breathing is an answer to a very hard problem: How do you get the resources that your cells need to survive, from the outside, to the inside of your cells? Every living thing has to solve this problem and the solution is surprisingly different depending on one of the most important regulators of life: Size.

    I swear the internet is better than my school Kurzgesagt taught me science. Bill Wurtz taught me history. Vsauce made me have an aneurysm. A hundred different people taught me math and English. SVname alone gave me more knowledge and entertainment than nine years of classes.

  • The Eyebrows
    The Eyebrows

    There is a single celled organism that is far larger than 1mm, in fact it's even bigger than an insect. It's the Caulerpa, a kind of green Algae. They can grow up to 12 inches, but do this by using specialized evolved organelles that imitate plant structures like stems and roots. So a bacteria might be able to get larger but would need to evolve some very specialized organelles.

    5:44 Life avoided that problem by forming multicellular organisms. Bhut why? Why do life wants us to be better and modified? Why do nature wants life to form, survive and improve? Why do the nature wants life to exist, that it is helping it?

    • Lünkel

      Nature doesn't want anything. What you're looking for here is evolution. The basic concept is the following: 1) organisms produce slightly different offspring, some are better and some worse (mutation and recombination) 2) Organisms which are better at reproducing become more common because, well, they make more offspring (natural selection) 3) These traits that were selected for then get passed on to future generations (heredity)

  • Vikas S

    "So at the very beginning LIFE needed to find a way to get good things in and bad things out" "So LIFE avoided this problem by forming a multicellular structures" "LIFE solved the diffusion problem by having holes and caves and tunnels and by folding in on itself" This is a design..Life is a design and it can't have started and developed on it's on..and for each and every design to exist there must be a's sad to see people be arrogant and never believe no matter how many evidence they find on his existence..

      Sorry man but NATURAL SELECTION 😎 Science does not require magical father in the sky or all those bullsh*t stories to explain human existance and can be understand and explored with scientific methot.
