no
Yes
Yes. Pretty much any multicelled organism will be eukaryotic.
an organism with many cells. another word for multicelled is multicellular. Its more complex. hope this helps!
The exchange of oxygen and carbon dioxide between an organism and its environment is known as respiration. In this process, oxygen is taken in by the organism and carbon dioxide is released as a waste product. Respiratory surfaces, such as lungs in mammals or gills in fish, facilitate this gas exchange by allowing for diffusion of gases between the organism and its surroundings.
Organ, since it is composed if cells, tissues, molecule, and multi-celled organisms. Multi-celled organisms are only composed of one then one cell.
In the lungs, exchange of gases occurs in the alveoli(sing: alveolus).
Obelia is a multicellular organism. It belongs to the class Hydrozoa, which consists of colonial organisms made up of individual polyps that are interconnected and function together as a single unit.
Not really. Organisms are either one celled or multicelled. Tri-cells can be formed by uni celled organisms for reproduction.
During the stage of photosynthesis, the exchange of gases occur in the leaves.
The primary function of the respiratory system is to provide for the exchange of respiratory gases(O2, CO2) between the organism and the environment.
monera is a single-celled organism. it is very simple and small e.g. bacteria and cyanbacteria
The unicellular organism is able to survive without a specialized respiratory system because it relies on simple diffusion of gases across its cell membrane for gas exchange. Its small size allows for rapid exchange of gases, ensuring the transport of oxygen and removal of carbon dioxide. Additionally, the organism's low metabolic rate allows it to meet its respiratory needs without the need for specialized respiratory structures.
