How do unicellular organisms transport gases and nutients?
Unicellular organisms transport gases and nutrients through processes like diffusion or active transport. Diffusion allows these molecules to move across the cell membrane from an area of high concentration to low concentration. In active transport, the cell uses energy to move molecules against their concentration gradient.
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.
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.
Transport system needed multicellular organisation?
A transport system is needed in multicellular organisms to efficiently distribute essential nutrients, gases, and waste products throughout the body. This system allows for the rapid and coordinated movement of materials to and from cells located far from the external environment. In multicellular organisms, individual cells are specialized for specific functions, and a transport system ensures that these specialized cells can work together effectively to maintain homeostasis and support the overall functioning of the organism.
What are the limits to diffusion as a means of transport for living organisms?
Diffusion becomes ineffective for larger distances or larger organisms because it is a slow process that relies on random movement of particles. Additionally, diffusion is not efficient for transporting materials against a concentration gradient, such as from low to high concentration. In larger organisms, diffusion is often supplemented by other transport mechanisms like circulatory systems to overcome these limitations.
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.
