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.
How do unicellular and multicellular organisms differ and how they meet their needs?
Unicellular organisms consist of a single cell that performs all necessary functions for survival, such as nutrient uptake and waste elimination, often through processes like diffusion. In contrast, multicellular organisms are made up of multiple cells that specialize in different functions, allowing them to efficiently meet complex needs through coordinated systems, such as circulatory and respiratory systems. While unicellular organisms rely on their environment for immediate resource access, multicellular organisms can transport resources internally and regulate their internal environments more effectively. This specialization in multicellular organisms enables them to thrive in diverse environments and perform more complex biological processes.

How do the cells of a multicellular organism function?
The main system that serves the needs of individual cells in multicellular organisms is the circulatory system. This is used to take waste away from individual cells and bring in new fuel such as proteins, glucose, and oxygen.
What are the basic needs that both unicellular and multicellular organisms need?
Both unicellular and multicellular organisms require basic needs for survival, including nutrients for energy and growth, water for biochemical processes, and a suitable environment to maintain homeostasis. Additionally, they both need to eliminate waste products to prevent toxicity. While multicellular organisms may have specialized systems for these functions, the fundamental requirements remain similar across both types of organisms.
Why is there a ventilation systems in multicellular organism?
Ventilation systems in multicellular organisms are important for the exchange of gases, such as oxygen and carbon dioxide, which are necessary for cellular respiration. These systems help ensure that oxygen is delivered to tissues and carbon dioxide is removed efficiently, supporting the metabolic needs of the organism.
Distinguish between unicellular and multicellular organisms?
Unicellular organisms have only one cell. They have a large surface area to volume ratio and rely on simple diffusion to meet their needs. Multicellular organisms have many cells. The cells are specialized and have a certain job to do.
Is eukaryotic multicellular?
Yes, eukaryotic organisms can be unicellular or multicellular. Eukaryotes, like animals, plants, fungi, and protists, are characterized by having cells with a true nucleus and membrane-bound organelles.
What is more advanced a unicellular or multi-cellular?
Multi-cellular organisms are more advanced than unicellular organisms because they have specialized cells that can perform specific functions, allowing for complex structures and functions to develop. Multi-cellular organisms also exhibit division of labor among cells, which enables them to adapt to a wider range of environments and challenges.
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.
Do all organisums have an organ system?
No. Organ systems only develop in larger, complex organisms. E.g. amoeba, a single celled organism, is small enough that all its needs can be obtained by the relevant organelles through diffusion. A dog, a large multi-cellular organisms, needs a system to deliver its requirements to the necessary tissues .
Why are multicellular organisms more efficent than unicellular organisms?
Multicellular organisms work like an assembly line, and if one part of a multicellular organism dies, it can be replaced, but if a part of a unicellular organism dies, the entire organism dies. The assembly line process is called specialization.
