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.

    A very large but thin bacteria could exist -- this maximizes surface area and minimizes interior. It could survive by capturing animals that trample on it and holding them til they die, expanding out over them to digest them after they've bit the dust.

    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?

      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)
