How do unicellular organisms transport gases and nutrients?
through their cell wall
Why is diffusion insufficient to meet the oxygen requirement for multicellular organisms like human?
In single-celled organisms the entire surface of the organisms is in contact with the environments for the diffusion of substances. In multi-cellular organisms all the cells may not be in direct contact with the surrounding environment. So simple diffusion will not meet the requirements of all the cells.
How do living organisms in soil help?
organisms decay and also poo there forth that makes methane gases and that's how it happens
What is a transport process by which gases move through a membrane?
Simple Diffusion
What is the correct order of respiration?
1. Glycolysis2. Krebs cycle3. Electron transportBut i have no idea.What_is_the_order_of_events_for_cellular_respiration
How do unicellular organisms transport gases and nutrients?

How do unicellular organisms do respiration?
diffusion of gases through the cell membraine.
What are the limits to diffusion as a means of transport for living organisms?
Diffusion is a rapid process and is therefore limited to shorter distances. Transport is includes the change of wastes, nutrients and gases.
Can unicellular organisms breathe using their cell?
If they're not using their cell, I'm not sure what else they would be using. There's only one cell to be used. If you're asking whether there is a "breathing mechanism" within the cell, then the answer is no. Unicellular organisms don't need an extensive respiratory system like multicellular organisms. Moreover, unicellular organisms couldn't "breathe" because no organelle supports such a thing. Instead, unicellular organisms get oxygen just through diffusion. Because unicellular organisms are small, the diffusion of oxygen into the cell is sufficient for cell respiration. In contrast, larger multicellular organisms can't obtain oxygen through diffusion alone because the oxygen couldn't "get" to every cell.
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
Do multi-celled organisms exchange gases?
no

Describe How the cell of stems exchange gases across their barriers?
Gas flows from higher partial pressures to lower partial pressures between cells
What has the author Gilberto Medeiros Kremer written?
Gilberto Medeiros Kremer has written: 'An introduction to the Boltzmann equation and transport processes in gases' -- subject(s): Transport theory, Kinetic theory of gases
How can gases enter the ocean water?
Their are 4 ways that gases enter the ocean. Gases can enter the ocean from streams, volcanoes, organisms, and the atmosphere.
What part of all organisms is involved in the exchange of gases?
the cells
What are the three phases of transferring gases between the environment and the cells?
The three phases of transferring gases between the environment and the cells: Breathing, the transport of gases and the exchange of gases. (Came straight from my biology textbook)
