Why fastidious organism grow poorly in chemically defined medium?
Fastidious organisms have complex nutrient requirements that may not be fully met by a chemically defined medium, which contains a limited set of known nutrients. These organisms may need additional growth factors or specific conditions that are present in more complex, undefined media. The lack of essential nutrients or factors in a chemically defined medium can result in poor growth or failure to grow at all for fastidious organisms.
Which tissue is responsible for transportation in a human body?
Blood - a fluid connective "tissue" - is the primary transport medium of substances, such as oxygen and nutrients, in the body.
How would you design another medium that would select for the same group of organisms?
One way to design another medium to select for the same group of organisms is to replicate the environmental conditions where these organisms thrive. For example, if the organisms grow well in acidic conditions, you could design a medium with a pH level that mimics their natural habitat. Additionally, you could include specific nutrients or substrates that the organisms prefer to consume.
Does nutrient agar supports the growth of more or fewer organism than a complex medium?
Nutrient agar supports the growth of fewer organisms compared to a complex medium because it contains fewer nutrients. Complex media typically have a more diverse array of nutrients, allowing for the growth of a wider variety of organisms.
What are 2 ways solutions are important for living things?
Solutions provide a medium for transportation of essential nutrients and waste products within living organisms. They also help in maintaining the proper pH levels in cells and body tissues, crucial for proper functioning of biological processes.
What life functions are carried out by unicellular organisms?
Well you see unicellular organisms are very unique in the fact that they live all on their own and move around with a flagellum or little motor, but to the point unicellular organisms carry out esscentally every function in life and they must in order to simply survive. One function is reproduction and they reproduce asexually

Do unicellular organisms need water?
All organisms, whether unicellular or not, need water to hydrate the surface of their cells. Without it, they would shrivel up and die. This is why germs like to grow on warm, wet surfaces (an orthodontic retainer, for example).
Are there any living creatures who do not have blood?
basic function of blood or a transport medium is to transport material within the body..there are unicellular (like bacteria) n simple multicellular organisms or u can say simple creatures do not have blood or any other transport medium..
What does medium contain?
Medium contains a suspension of cells or microorganisms, along with nutrients and other components necessary for their growth. It provides an environment for these biological entities to thrive and multiply. The composition of the medium can vary depending on the specific needs of the organisms being cultured.
What role seawater play in the hydrosphere?
Seawater is a major component of the hydrosphere, covering about 70% of the Earth's surface. It plays a crucial role in regulating the Earth's climate through its capacity to store and release heat. Seawater also helps support marine life by providing habitat, nutrients, and serving as a transportation medium for various organisms.
Why do most multi-cellular organisms have a circulatory system?
Unicellular and some simple multicellular organisms get nutrients from and dispose of waste products into the surrounding environment directly through their cell membranes (mainly by diffusion, molecular pumps, and endo/exocytosis). This is only energy efficient when a large enough surface area of the organism can be exposed to the surrounding medium because it's difficult to transport materials across more than a few layers of cells. Larger organisms get around this by utilizing circulatory vessels to bring nutrients to and waste products away from cells deeper in the organism's interior. An analogy would be using aqueducts to get water in and sewer plumbing to get waste out of the interior portions of a land mass. This is also why generally single celled organisms tend to be very small. Otherwise their surface area-to-volume ratio would be too large to get nutrients into the cell's interior.
What is the difference between complete and minimal medium?
Complete medium contains all the nutrients required for the growth of a particular organism, while minimal medium contains only the essential nutrients necessary for growth, often lacking specific components that the organism may be able to synthesize on its own. Complete medium is used for general growth of organisms, while minimal medium is used for specific studies or to select for strains able to synthesize missing components.
