Living things differ from non living things because they are made of cells and contain DNA, transform and metabolize energy, and reproduce. They also grow and develop, respond and react to internal and external influences, and can evolve and adapt.Continue Reading
Anything in this world is either living or non-living. All living things, from simple unicellular organisms like amoeba to multicellular organisms like humans, are composed of one or more cells and contain a genetic code in the form of DNA. Since life forms require energy to sustain life they have metabolic processes to transform, store or release energy and synthesize nutrients. For example, humans inhale oxygen during respiration to release energy from foods consumed. Plants absorb light energy to manufacture nutrients during photosynthesis.
Living things grow and mature during their life circle. Their cells increase in number or grow in size, and differentiate into specialized groups. Living things have variety of methods to reproduce. Eventually all living things die and are transformed into other types of energy. They also respond to different internal and external stimuli.
Movement and excretion are two similarities between living things and some non-living things. For example, a car can move, break down fuel and release carbon dioxide.Learn more about Biology
Adenosine triphosphate, or ATP, is the energy currency of life, the way that individual cells store and use chemical energy. Any food or other source of energy a cell takes in is converted to ATP, in which form the mechanisms of the cell can easily use it. It does this by shedding a phosphate group, becoming adenosine diphosphate, or ADP, a highly energetic reaction that powers all of a cell's molecular machinery.Full Answer >
Characteristics that all living things have in common are: growth, reproduction, they are made up of cells, they respond and adapt to their environment, and obtain and utilize energy. An organism must exhibit all of these characteristics to be classified as a living thing. However, living organisms can have different levels of cellular organization.Full Answer >
The characteristics that all living things share are cells, growth, reproduction, adaptation, homeostasis, use of energy and response to the environment. Using these characteristics, it is easy to determine if something is living, dead or non-living.Full Answer >
The main purpose of cellular respiration is to convert biochemical energy from nutrients into adenoside triphosphate, or ATP, a chemical energy needed by cells to perform certain functions. Muscle and brain nerve cells require energy that contains a high number of mitochondria to perform effectively.Full Answer >
