Why must complex muticellular organisms have transport systems?

∙ 11y ago
Large organisms need transport systems to supply all their cells with food, oxygen and other materials.Multi-cellular organisms are too big and not all of their cells have contact with the external environment. All organisms need to exchange substances with their environment - take in needed molecules and get rid of waste. A uni-cellular organism can use the processes of osmosis, diffusion and active transport to transport substances in and out of the organism, which is in this case just one cell. But as organisms increase in size, they need a specialized transport system to exchange substances between the internal environment and the external environment. Interestingly enough, osmosis and diffusion are still the important mechanisms at the cellular level.

Are arthropods complex or simple organisms?
Arthropods are complex organisms. They are made up of cells, tissues, organs, and organ systems.
Which organism lacks a specialized transport system?
Certain organisms lack a specialized transport system for moving nutrients around the body. These organisms generally lack advanced circulatory systems.
How do organs and organ systems evolve and change from simple to more complex organisms?
Through DNA code that tells the cells how to evolve.
What is the definition of complex adaptive systems?
Complex adaptive systems are genetic algorithms which involve many components that adapt as they interact. Properties of complex adaptive systems include:Emergent behaviorAdaptationSpecializationDynamic ChangeCompetitionCooperationDecentralization
In what ways are the transport systems different for plants and animals?
Plant transport systems help to get water through the roots, stems and leaves. Animals transport systems get oxygenated blood around the system.
Are arthropods complex or simple organisms?
Arthropods are complex organisms. They are made up of cells, tissues, organs, and organ systems.
Least comlex to most complex?

Which organism lacks a specialized transport system?
Certain organisms lack a specialized transport system for moving nutrients around the body. These organisms generally lack advanced circulatory systems.
What is the difference between simple and complex organisms?
Simple Organism some simple organisms are made of single cell. Others are made of many cells that are similar Complex organisms in complex organisms, cells are organized into tissues, which make up organs. Organs form organ systems.
How does the list from simplest to the most complex go?
Cells, Tissues, Organs, Organ Systems, Organisms.
What is an applied science that is concemed with biological systems living organisms or derivatives thereofto make products for specific use?
Complex systems biology
What is level or organization?
Multicellular organisms have 5 levels of organization ranging from simplest to most complex...cells, tissues, organs, organ systems, organisms.
Do all organisms have organs tissues and organ systems give examples to support your answer?
No. Single celled organisms such as amoeba obviously don't have them. Slightly more complex organisms such as sponges don't have organs or organ systems though they might be said to have tissues.
What are complex organisms?
Complex organism generally means multicellular, but in that category there are different levels of complexity. Sponges are multicellular, but don't have distinct tissue, for example. Generally, any living thing that you can see with your naked eye is extremely complex.
Why human considered as complex organism?
Humans are considered to be complex organisms as the numerous organ systems present in it work simultaneously and help the human body work. The complexity of the body lies in the simultaneous working of the organ systems.
How are complex organisms organized?
Usually, complex organisms consist of many organ systems, which comprise from two or more organs, which is from two or more tissues, which comes from two or more cells working for the common function.
Do all organisums have an organ system?
No. Organ systems only develop in larger, complex organisms. E.g. amoeba, a single celled organism, is small enough that all its needs can be obtained by the relevant organelles through diffusion. A dog, a large multi-cellular organisms, needs a system to deliver its requirements to the necessary tissues .
