Eukaryotic cells contain membrane bound organelles, such as mitochondria, a nucleus, and chloroplasts. Prokaryotic cells probably transitioned into eukaryotic cells between 2.0 and 1.4 billion years ago. This was an important step in evolution. In contrast to prokaryotes, eukaryotes reproduce by using mitosis and meiosis. Sex appears to be a ubiquitous and ancient, and inherent attribute of e… WebWhen we breathe in air, it goes into lungs and oxygen diffuses from the lungs into our bloodstream.
