Characteristics of Living Things
Organisms make more organisms of the same type
Reproduction
Autotrophs can make their own, while heterotrophs must consume other organisms to get this.
Energy
Living things always have __________ but nonliving things will never have _________.
Cells
These particles are not living things. They often affect the cells of one specific species. They cannot reproduce on their own, but do evolve very quickly.
Viruses
Living things have to carry out a lot of processes to stay alive. This characteristic is all about how those processes are powered...
Obtain and Use Energy
These prokaryotes are very simple organisms. Many types are helpful to humans, like those in the gut that help us digest food and obtain nutrients. Others are harmful and cause infection.
Bacteria
This idea is no longer believed to be true because we now know that living things only come from other living things through reproductive processes.
What term is used to describe the idea that living things can come from nonliving things? (for example it was thought that maggots came from rotting meat)
Spontaneous Generation
Living things get larger and mature or change forms.
Growth and Development
A living thing changes its behavior based on signals from their internal or external environment
Response to Stimuli
These organisms are decomposers. Some can be helpful for humans, while others can be harmful.
Fungi
When a living thing has a bacterial infection, this treatment can help kill the bacteria.
Antibiotic
Prokaryotes are generally much simpler and smaller than eukaryotes. What is the other major difference between these types of organisms/cells?
Prokaryotes have no membrane bound organelles (like a nucleus) while eukaryotes do have membrane bound organelles.
Organisms must maintain a stable internal environment. This is sometimes called regulation.
Homeostasis
Over many generations, a species adapts to the environment
Evolution
This kingdom is full of eukaryotes that cannot be categorized into the other kingdoms in the Eukarya domain (plants, animals, or fungi)
Protists
A small amount of an inactive virus can help train the immune system to recognize and destroy a virus before it makes someone sick
Vaccine
How do multicellular organisms FUNCTION differently than unicellular organisms?
In unicellular organisms, one cell must carry out all the processes to stay alive.
In multicellular organisms, cells can specialize to perform specific jobs. They work together to carry out life's processes and keep the organisms alive.
