How do plant cells placed in a medium for tissue culture change answer in terms of their degree of specialization?
In tissue culture, plant cells undergo dedifferentiation, where specialized cells revert to a more generalized, undifferentiated state. This process allows them to proliferate and form callus tissue, which can then differentiate into various types of cells depending on the provided growth conditions. Consequently, the degree of specialization decreases initially, as cells lose their specific functions to regain the ability to develop into new plant structures. Ultimately, with the right cues, these cells can redifferentiate into specialized tissues again.

How do the plant cells placed in the medium for tissue culture change in terms of their degree of specialization?
In tissue culture, plant cells often revert to a less specialized state, becoming more embryonic or callus-like as they adapt to the in vitro environment. This de-differentiation allows them to proliferate and regenerate into new tissues or organs. As they grow, they may then re-differentiate into specialized cells under the influence of specific growth regulators, allowing for the development of whole plants from these initially unspecialized cells. Thus, tissue culture facilitates both the reduction of specialization and the potential for subsequent specialization in a controlled setting.
How do the plant cells placed in a medium for tissue culture change in terms of their degree specialization?
In tissue culture, plant cells typically undergo a process of dedifferentiation, where specialized cells revert to a more generalized, meristematic state. This allows them to regain the ability to divide and differentiate into various cell types needed for growth and development. As a result, these cells can adapt and form new tissues or organs, making them less specialized than they were in their original context. Ultimately, this process enhances their potential for regeneration and propagation in a controlled environment.
When light enters from denser medium to rare medium what happens to its phase change?
When light enters from a denser medium to a rarer medium, the phase change it experiences is a shift towards a longer wavelength, known as refraction. This shift in phase is due to the change in the speed of light as it travels through the different mediums.
Different ways of inoculating a culture medium?
Some common methods of inoculating a culture medium include streaking with an inoculation loop, spreading with a sterile spreader, and pouring a liquid culture onto the medium. Additionally, a pipette can be used to spot-inoculate specific areas on the medium or a swab can be used to directly streak the surface.
What is it called when feces are placed in a growth medium for bacterial analysis?
This process is called fecal culture or stool culture, where feces are placed in a specific growth medium to allow bacteria to grow and be identified.

How are acids detected in a culture medium?
use glucose phosphate broth , inoculate the organism in that broth and incubate at 37 degree celsius for 24 hrs.
What factor can cause cells to divide in a culture medium?
Protein signals cause cells to divide in a culture medium.
What is Stuart's medium?
Stewart's medium is a type of culture transport medium (in broth form) used to preserve bacteria until it is cultured. Stewart's medium can be found in specific culture test tubes.
How are acid and alkaline products typically detected in a culture medium?
Acid and alkaline products in a culture medium can be detected using pH indicators that change color based on the acidity or alkalinity of the medium. pH strips or pH meters are commonly used to measure the pH levels of the medium and determine the presence of acid or alkaline products. Additionally, microbial growth patterns and metabolic byproducts can also indicate the presence of acid or alkaline substances in the culture medium.
Why is there no refraction when a wave enters a new medium at exact 90-degree angle?
When a wave enters a new medium at a 90-degree angle, it doesn't change its direction because the boundary between the two media is behaving like a mirror, reflecting the wave back with no refraction. Refraction occurs when the wave enters the new medium at an angle other than 90 degrees, causing it to change speed and direction.
What is a culture medium consisting of agar human blood and beef heart?
Complex medium
Different ways of inoculating a culture medium?

What happens to the light that is directed to a medium with different density?
When light travels from a medium with one density to a medium with a different density, it can change speed and direction. This change in speed and direction is called refraction. The degree of bending of the light depends on the difference in densities between the two mediums.
What is it called when feces are placed in a growth medium for bacterial analysis?
This process is called fecal culture or stool culture, where feces are placed in a specific growth medium to allow bacteria to grow and be identified.
