The common traits of all living things have been identified by biologists. Though nonliving things exhibit some of the same characteristics, all living things are made up of specialized and coordinated parts. All living things contain one or more cells, which are essentially the building blocks of life. The cells themselves are made up of atoms, molecules, cell organelles, and other structures. The cells then collaborate with other tissues to create organs and systems. Among all the similarities in the makeup of all living things, the structure of the body is one of the biggest ones.
There are many types of living things, from plants and animals to fungi and algae. These organisms can be found in every type of habitat on Earth, from lakes and rivers to oceans. And because all living things have a common ancestor, they all share many traits. To begin with, all living things are capable of reproduction. They all use the same kinds of molecules in their bodies and translate these into a range of daily activities.
All life is highly ordered. Cells are made up of cellular structures, and many living things have larger-scale structures, including mitochondria and chloroplasts. Most living things reproduce sexually or asexually, and they grow to maturity. This is how we know they are alive. All living things need water to survive. Moreover, water is essential for many chemical reactions inside cells. It also helps transport nutrients and eliminate waste matter. It is therefore no surprise that water is the most essential of all living things.
