Both unicellular and multicellular organisms share the characteristics of life: they grow, respond to stimuli, maintain homeostasis (an internal balance), reproduce, pass on genetic material to offspring, and obtain or use energy.
Difference Between Unicellular And Multicellular Organisms
Unicellular Organisms | Multicellular Organisms |
---|---|
Unicellular organisms are composed of a single cell | Multicellular organisms are composed of more than one cell |
Simple body organization | Complex body organization |
Unicellular organisms include bacteria, protists, and yeast. For example, a paramecium is a slipper-shaped, unicellular organism found in pond water. It takes in food from the water and digests it in organelles known as food vacuoles.
Unicellular sentence example
Multicellular organism, an organism composed of many cells, which are to varying degrees integrated and independent.
Plants are all multicellular and consist of complex cells. In addition plants are autotrophs, organisms that make their own food.
Multicellular sentence example
Examples of organism in a Sentence A human being is a complex organism.
Protists sentence example I must admit that I always get confused by all these little flagellated protists . The Museum’s enormous collections are ranked 4th in America in size, and include protists , plants, invertebrates and vertebrates. It is not so difficult to raise Paramecium or other protists with a hay culture.
Homeostasis sentence example. Consuming foods that contain probiotics is just one way of encouraging your body’s homeostasis . It is essential to maintain the homeostasis between the body’s biological processes.
The maintenance of healthy blood pressure is an example of homeostasis. Your body (and a healthy intake of fluids) maintains a proper water balance so that neither of these situations occurs. Calcium levels in the blood must be maintained at proper levels. The body regulates those levels in an example of homeostasis.
Homeostasis, from the Greek words for “same” and “steady,” refers to any process that living things use to actively maintain fairly stable conditions necessary for survival.
Other Examples of Homeostasis
What is another word for homeostasis?
equilibrium | balance |
---|---|
evenness | stability |
equanimity | equipoise |
endocrine system
However, the organ systems also work together to help the body maintain homeostasis. For example, the cardiovascular, urinary, and lymphatic systems all help the body control water balance.
Some organs are in more than one system. For example, the nose is in both the respiratory system and also is a sensory organ in the nervous system. The testes and ovary are both part of the reproductive systems and endocrine systems.
Introduction. The tendency to maintain a stable, relatively constant internal environment is called homeostasis. The body maintains homeostasis for many factors in addition to temperature. For instance, the concentration of various ions in your blood must be kept steady, along with pH and the concentration of glucose.
