How does exchange of gases takes place in unicellular organisms?
Gas exchange takes place at a respiratory surface-a boundary between the external environment and the interior of the organism. For unicellular organisms the respiratory surface is governed by Fick's law, which determines that respiratory surfaces must have:a large surface areaa thin permeable surfacea moist exchange surface.Read more: How_does_gas_exchange_take_place
Why must complex muticellular organisms have transport systems?
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.
A source from which organisms generally takes elements is called?
It is an exchange pool.
What is the source from which organisms generally take elements is called?
Exchange pool.
Describe How the cell of stems exchange gases across their barriers?
Gas flows from higher partial pressures to lower partial pressures between cells
How do Unicellular organisms exchange gas eliminates wastes and absorbs nutrients?
directly through their cell membranes

Where diffusion occur in living organisms?
Diffusion is one of the processes of transferring materials within the cells of living organisms. An example of diffusion is the exchange of gases in the lungs.

1. What basic life processes must all unicellular organismsperform in order to survive?
All unicellular organisms must perform basic life processes in order to survive. These processes include: Metabolism: Unicellular organisms need to generate energy from the consumption of food and other organic molecules. This energy is used for various activities such as growth, reproduction, and movement. Growth: Unicellular organisms must grow and divide in order to increase their population size. Movement: Some unicellular organisms have the ability to move in order to find food, avoid predators, and reproduce. Reproduction: Unicellular organisms must be able to reproduce in order to increase their population size. This can be done asexually, through binary fission, or sexually, through the exchange of genetic material. Excretion: Unicellular organisms must excrete waste products in order to maintain homeostasis. Sensing the Environment: Unicellular organisms must be able to sense their environment in order to detect changes in temperature, pH, and other factors that could affect their survival. Responding to Stimuli: Unicellular organisms must be able to respond to changes in their environment by making appropriate adjustments in order to survive. In summary, all unicellular organisms must perform basic life processes such as metabolism, growth, movement, reproduction, excretion, sensing the environment, and responding to stimuli in order to survive.
Which body system Transportsneeded materials to the cellsand carrying the wastes away from cells?
The circulatory system - capillaries exchange oxygen for carbon dioxide, as well as transport materials into and out of the cell.
Why are the levels in multicellular organisms not used to describe unicellular?
The levels in multicellular organisms are not used to describe unicellular organisms because they are not very similar to the other levels. They contain different characteristics so they need their own sub levels.
