Living things are biological structures that respond to changes in the environment or within their own entities. This includes animals, plants, fungi and the single-celled organisms known as bacteria. Living things have complex biochemical organizations that allow them to process substances and utilize energy in order to respond to changes around them.Know More
According to New Mexico Tech, all living things display the seven characteristics of life. The first of these is that they are comprised of cells. Single-celled organisms have only one cell that completes all of the necessary tasks of life, while multicellular organisms have many specialized cells. Living things are also complexly organized, both on the molecular and cellular level. In multicellular organisms, cells are organized into tissues, and tissues are organized into organs.
In order to be considered a living thing, a structure must take in energy and use it not only to respond to the environment, but also to grow and maintain itself. Living things grow in several ways; cells divide to form new cells, cells become larger, and an organism increases in size as its number of cells increases. The sixth characteristic of life is the ability to reproduce, and the seventh is the ability to adapt to the environment. Though individual organisms may not satisfy these final two characteristics, groups of similar organisms must in order to be considered "living things."Learn more about Biology
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 >
Living things reproduce, grow, adapt to the environment, respond to stimuli and metabolize. They also undergo homeostasis, collect and convert nutrients, and use energy. Living things are organized into one or more cells. The five groups of living things are the animal, plant, monera, protista and fungi kingdoms.Full Answer >
A nonliving thing is no longer living or has never had the traits of life including respiration, reproduction, movement, metabolism, sensitivity and growth. Nonliving things do not require energy to continue existing in their current state.Full Answer >
The oldest living thing on Earth is Pando, a grove of quaking aspens located in Utah's Fishlake National Forest. Scientists estimate that Pando is 80,000 years old as of 2014.Full Answer >
