Does homeostasis occur in unicellular or multicellular organisms?
Wiki User
∙ 12y ago
The cells of multicellular organisms become specialized for particular tasks and communicate with one another to maintain homeostasis. Specialized cells in multicellular organisms are organized into groups. A tissue is a group of similar cells that performs a particular function.

What is a special type of asexual reproduction that occurs in multicellular eukaryotic organisms?
The 3 forms are budding, regeneration, and runners.
By which method does the development in multicellular organisms occur?
They receive instructions in their DNA.
Homeostasis can occur at the cellular level or the system level true or false?
No organism can "maintain" homeostasis. Everything dies in the long run! Other than that, it depends on the organism. Unicellular organisms like bacteria have no problem maintaining homeostasis at a cellular level, [but complex multicellularorganisms like us are dependent on the other cells and organ systems of our body (not to mention other organisms) to survive].
Why are the levels in multicellular organisms not used to describe unicellular?
The levels in multicellular organisms are not used to describe unicellular organisms because they are not very similar to the other levels. They contain different characteristics so they need their own sub levels.
How does the process of homeostasis help cells of all organisms?
Homeostasis is the process of regulating the internal environment so that it remains constant. This helps cells because it reduces the stress placed on the cell that would occur with changing solute concentrations, temperature, etc.

May occur in the cell shape of some unicellular organisms as life functions are carried out?
Changes may occur in the cell shape
What are three characteristics of algae?
Algae (singular: alga) are photosynthetic, eukaryotic organisms that do not develop multicellular sex organs. Algae can be unicellular, or they may be large, multicellular organisms. Algae can occur in or fresh waters, or on the surfaces of moist soil or rocks. The multicellular algae develop specialized tissues, but they lack the true stems, leaves, or roots of the more complex, higher plants.

A cell normally undergoes apoptosis when?
A cell normally undergoes apoptosis when it dies. It is the process of programmed cell death that might occur in multicellular organisms.
How did cell specialization occur in multicellular organisms?
Specialization occurred during the process that moved from unicellular organisms to multicellular organisms. Selection pressures favored having numerous distinct cells that work in tandem over individual cells that did not and then further cells that were in complete union with each other over those that work in tandem. There are a number of intermediate steps between unicellular and multicellular organisms. Probably the most clear "midway" point is the colonial organism of which the extant Volvox is one of the best examples. (Admittedly Volvox itself is only 200 million years to present old, so it is not a remnant of this transition, but is similar to what scientists surmise was part of the transition that led to the development of multicellular organisms.) In a colonial organism, numerous unicellular organisms work in tandem to achieve goals (similar to how geese fly in flocks even though each is autonomous). The required communication would select cells that more effectively communicate with each other, leading to cells that can function as part of the same organism. In Volvox, we also already see small degrees of specialization. There are distinct somatic cells which perform day to day activities such as motion and photosynthesis and germ cells which are primarily responsible for replication. Since no cell could adequately perform both functions well, this partial specialization is favored. In organisms performing more complex tasks, this differentiation in tasks would naturally be selected for enlargement. You can read more about it in the Royal Society report below.

How does osmoregulation occur in unicellular organisms?
Osmoregulation in unicellular organisms is by active transport. For example in Paramecium - osmoregulation is done by organelles called contractile vacuoles. These contractile vacuoles are spherical shaped structures surrounded by a series of radiating ducts. These ducts collect water and pump it into the central area by means of contractile fibres that contract and force the water into the center. When the vacuoles are full the unicellular organism contracts forcing the water outside the cell.
What is two reasons for cell reproduction in multicellular organisms?
In single-cell organisms it is reproduction by the means of binary fission,where one cell becomes two separate cells. In multi-cellular organisms ( fungi,plants,animals ),it is all about growing
What is the difference between a single celled organism circulatory system and a humans circulatory system?
Unicellular: Exchanges occur directly with enviroment Multicellular: Diffusion is not possible unless diffusion across body surface. Transporting substances over long distance in animals.
