Complex organisms need cells that perform many different functions. Complex organisms are capable of a lot of different things, and that variety needs to be supported on the cellular level. Without them, complex organisms cannot perform different functions.

Why unicellular organisms do not have specific organs?
Unicellular organisms are composed of only one cell and thus do not have the need for specialized organs like complex multicellular organisms. Instead, they carry out all necessary functions within a single cell, such as obtaining nutrients, metabolizing, reproducing, and responding to the environment using simple structures like organelles. This efficiency allows unicellular organisms to survive and thrive in diverse environments.
Do more complex organisms need more energy than simpler organisms?
Yes, generally more complex organisms require more energy to support their increased metabolic demands. This is because complex organisms have more specialized cells and tissues, perform more complex functions, and require larger and more efficient organ systems to sustain their body functions.
How is the cell of a one-celled organism different from the the cells of many-celled organisms?
One cell or unicellular organism cells are of simpler forms mostly prokaryotes. In one cell organisms all the vital functions which are necessary for the life is carried by the same cell. In many cell or multicellular organisms the cells are complex and are called eukaryotic cells. In multicellular organism the cells are divided and are specialized in performing different functions according to need as some cells like blood work to carry oxygen, some cell hv functions like secreating some fluids like hormones or vitamins.
Why does complex multicellular organisms need a nervous system?
Complex multicellular organisms have specialized cells that need to communicate quickly and efficiently to respond to external stimuli, coordinate movement, and maintain internal balance. The nervous system allows for rapid communication through electrical impulses, enabling these organisms to adapt to their environment and survive.
Why do cells in your body need to be specellized?
Multicellular organisms are much more complex. The body needs to supply food and nutrients, transport materials, remove wastes, and fight infections. Specialized cells carry out different functions in order for the body to function properly.
Why are complex organisms made up of specialized cells?
Complex organisms need cells that perform many different functions. Complex organisms are capable of a lot of different things, and that variety needs to be supported on the cellular level. Without them, complex organisms cannot perform different functions.

Why do multicellular organisms need specialized tissues?
Cell specialization is necessary to support multicellular life because multicellular organisms need different tissues. This means it needs cells to make up those tissues and perform different functions.

Why is there no hierarchy of organization within single celled organisms?
Because there is only one cell and they are not as complex as multi celled-organisms. Example: A rabbit needs to perform more functions, while a single celled organism, such as amoeba, doesn't need to perform a lot of functions. The rabbit is more complex, so it has a hierarchy of organization.
When government became more complex was there need for specialized workers?
true
Distinguish between unicellular and multicellular?
The main distinction between unicellular and multicellular is the number of cells. Unicellular organisms survive on a single cell while multicellular means that they need a number of cells to survive.
Why does complex multicellular organisms need a nervous system?
Complex multicellular organisms have specialized cells that need to communicate quickly and efficiently to respond to external stimuli, coordinate movement, and maintain internal balance. The nervous system allows for rapid communication through electrical impulses, enabling these organisms to adapt to their environment and survive.

How do you simple single celled organisms get oxygen?
Simple single-celled organisms like bacteria and protozoa absorb oxygen directly from their environment through their cell membrane. This allows them to take in the oxygen they need for respiration without the need for complex respiratory structures.
What the advantages of having different type of cell?
Having different types of cells allows for specialized functions within an organism, leading to efficient division of labor. This specialization enables complex organisms to perform a wide variety of tasks. Additionally, different cell types can work together to carry out complex biological processes essential for survival and growth.
