The cell (from Latin cella, meaning "small room"[1]) is the basic structural, functional, and biological unit of all known living organisms. Cells are the smallest unit of life that can replicate independently, and are often called the "building blocks of life".
In chapter one of Essential Biology by Campbell summarizes how the world operates, the way organisms operate and the different cells that make up an organisms . Chapter one also speaks about Darwin’s theory of survival of the fittest and lastly the process of the scientific method. Firstly there are seven properties to which we associate with life. Order is one of the main properties of life because without any order our bodies would not be able to function properly. Different cells …show more content…

Some people live their lives not realizing how their body works or how their world works around them. There are reasons behind our body temperature dropping; one will get sick because we need to maintain a certain temperature for our bodies to work properly. This is called regulation and how our bodies react to the environment through sweating to cool our bodies when its hot so we can maintain our body temperature. Another property associated with life is growth and development which is why organisms do not stay a baby forever with time they grow from a child to a teen to an adult. When a bird is first born they are unable to fly but through growth and development, they mature enough to learn the process of flying. In order for an organism’s bodies to work, energy is needed. The food they digest is turned into energy so that they can function properly throughout the day. This process is called energy processing. Many people become confused between response to the environment and regulation. Regulation is how organisms react to the environment that is what is expected to happen like sweating when it's hot which is an inner body reaction. Response to the environment is more …show more content…

The biosphere is the earth, the higher power that houses every living thing and non living thing, ecosystems, communities, populations and organisms. Then the organ systems and organs, tissues, cells, organelles and molecules, atoms all make the organism. This goes back to one of the seven properties of life known as order that is showing the organization and the different stages which make up the biosphere. Ecosystems are a place where all living and nonliving things exist. For example in the rainforest there are water, trees, animals and everything needed for all living things to survive. Living things need to interact with nonliving things such as animals drinking water in order to keep them hydrated and healthy. Within an ecosystem, there are communities. Within an ecosystem, you will not see a fish living in a tree. They would be in their community, the ocean, along with whales, seaweed, plants and jellyfish. Within the community, there are different types of species such a group of whales that are one species or a group of jellyfish another species. One cannot class a whale with a jellyfish. Although they live in the same communities they carry different DNA and are from different populations that also goes back to reproduction; organisms can only reproduce their kind. Then there are organisms meaning one specific living thing such as a jellyfish or a human. Organisms are
