How do unicellular organisms transport gases and nutrients?
Unicellular organisms transport gases and nutrients through simple diffusion across their cell membrane. This process allows molecules to move from an area of high concentration to an area of low concentration without the need for specialized structures like a circulatory system. This works efficiently due to the small size and high surface area-to-volume ratio of unicellular organisms.
How unicellular organisms and multicellular organisms exchange materials?
Unicellular organisms exchange materials through diffusion or active transport across their cell membrane. Multicellular organisms exchange materials through specialized structures like respiratory and circulatory systems that transport gases and nutrients throughout the body, as well as through cellular communication and coordination.
How do unicellular organisms meet their basic needs?
Unicellular organisms meet their basic needs by metabolism (eating, drinking, breathe, and excrete) , growth (how big do they grow), Reproduction, irritability (how do they react to heat and cold, how do they react to danger), adaptation (how do they compete for food and space to survive) and movement (how do they move).
Give two reasons why lower organisms eg bacteria and simple multicellular do not have an elaborate transport system?
Lower organisms like bacteria and simple multicellular organisms do not have an elaborate transport system because their small size allows for nutrients and gases to easily diffuse across their cell membranes. Additionally, their simple body structures do not require the complexity of a specialized transport system as they can rely on passive diffusion for their basic needs.
How multicellular organisms exchange materials?
Multicellular organisms exchange materials through mechanisms such as diffusion, active transport, and bulk flow. These processes occur through specialized structures like cell membranes, blood vessels, and respiratory or digestive systems, enabling the transport of gases, nutrients, and wastes throughout the organism's body.

How do unicellular organisms do respiration?
diffusion of gases through the cell membraine.

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?
In unicellular organisms, gases are exchanged through simple diffusion across the cell membrane. Oxygen from the environment diffuses into the cell, while carbon dioxide produced by the cell diffuses out. This process is driven by concentration gradients, where gases move from areas of higher concentration to areas of lower concentration.
How does the method of internal transport of gases differ in earthworms and planarians?
Earthworms utilize their moist skin for gas exchange through diffusion, while planarians have a branching system of tubes called flame cells that help transport gases using cilia-driven fluid movements. This difference in internal transport of gases reflects the varying complexities in respiratory systems between the two organisms.
Does an amoeba have a heart?
No, an amoeba does not have a heart. Amoebas are single-celled organisms that do not possess a circulatory system like more complex organisms. They rely on diffusion to transport nutrients and gases within their cell membrane.
Do bacteria have blood?
no it does not, only living organisms that are vetebrates have blood

What transport mechanism do one celled colonial and simple multicellular organisms rely on?
These organisms use simple diffusion as a transport mechanism.This is possible because of the small size of the organisms. Diffusion is effective over small distances but as size increases it becomes less and less efficient.
Unicellular organisms can perform all of their own functions including respiration and ingestion and digestion and excretion and reproduction?
Yes, unicellular organisms are capable of performing all of these functions independently because they consist of just one cell that can carry out various life processes on its own. They can respire by exchanging gases through their cell membrane, ingest and digest food within their single cell, excrete waste products, and reproduce through binary fission or other forms of asexual reproduction.
