Define regeneration.

Question

Answer

The action or process of regenerating or being regenerated.

Answer

Regeneration is the process of renewal, restoration, and growth that makesgenomes, cells, organisms, and ecosystemsresilient to natural fluctuations or events that cause disturbance or damage.[1] Everyspecies is capable of regeneration, frombacteria to humans.[2][3] Regeneration can either be complete[4] where the new tissue is the same as the lost tissue,[4] or incomplete[5]where after the necrotic tissue comesfibrosis.[5] At its most elementary level, regeneration is mediated by the molecular processes of gene regulation.[6][7]Regeneration in biology, however, mainly refers to the morphogenic processes that characterize the phenotypic plasticity of traitsallowing multi-cellular organisms to repair and maintain the integrity of their physiological and morphological states. Above the genetic level, regeneration is fundamentally regulated by asexual cellular processes.[8] Regeneration is different from reproduction. For example, hydra perform regeneration but reproduce by the method ofbudding.

Answer

THE process of getting back a full  ..ORGANISM from its body part is called .............REGENERATION...

Answer

When the new organism is produced from the parent organism in many parts ,it is known as regeneration. Eg.planaria

Answer

Regeneration is a type of asexual mode of reproduction in which an organism restores or regenerates the body parts it has lost due to any accident. It might seem similar to fragmentation but fragmentation occurs due to maturity while the latter occurs due to any accident.

Answer

Definition of regeneration. 1 : an act or the process of regenerating : the state of being regenerated. 2 : spiritual renewal or revival. 3 : renewal or restoration of a body, bodily part, or biological system (such as a forest) after injury or as a normal process.

Answer

Regeneration is retained

In biology, regeneration is the process of renewal, restoration, growth that makes genomes, cells, organisms and ecosystem resilient to natural fluctuations or events which cause disturbance or damage.

Answer

It is the process of obtaining the lost part

Answer

Regeneration

Regeneration is the process by which living organisms or cells replace damaged or lost body parts, tissues, or organs to restore their normal form and function. It is a fundamental biological process that occurs in various organisms across the animal and plant kingdoms. Regeneration can occur at different levels, ranging from cellular regeneration to complete tissue or organ regeneration.

Types of Regeneration

Regeneration can be classified into two main types:

1. Epimorphosis:
- Epimorphosis is the process where lost body parts or tissues are regenerated through the proliferation of existing tissues.
- The regeneration occurs by the formation of a blastema, a mass of undifferentiated cells capable of giving rise to various cell types.
- The blastema undergoes cell proliferation, differentiation, and patterning to replace the lost or damaged tissues or organs.
- Examples of epimorphosis include the regeneration of limbs in salamanders and the regeneration of liver tissue in mammals.

2. Morphallaxis:
- Morphallaxis is the process where regeneration occurs by remodeling or reshaping existing tissues without the formation of a blastema.
- The existing tissues undergo remodeling or reorganization to restore the lost or damaged parts.
- This type of regeneration is common in organisms like hydras, planarians, and some sea anemones.

Mechanisms of Regeneration

The process of regeneration involves intricate cellular and molecular mechanisms that vary depending on the organism and the type of tissue or organ being regenerated. Some key mechanisms involved in regeneration include:

1. Cellular Dedifferentiation:
- Dedifferentiation is the process where specialized cells revert to a less specialized or undifferentiated state.
- During regeneration, dedifferentiated cells provide a source of progenitor cells that can differentiate into the required cell types for tissue or organ reformation.

2. Cell Proliferation and Migration:
- Regeneration involves the rapid proliferation of cells in the regenerative zone or blastema.
- These cells migrate to the site of regeneration to replace the lost or damaged tissues.

3. Extracellular Matrix Remodeling:
- The extracellular matrix, which provides structural support to tissues, undergoes remodeling during regeneration.
- This remodeling allows for the proper organization and integration of newly formed cells into the regenerated tissue or organ.

4. Guidance and Patterning:
- Regenerating tissues or organs often require proper guidance and patterning to restore their original structure and function.
- Molecular signals and gradients play a crucial role in guiding cell migration, differentiation, and tissue organization.

Applications of Regeneration

Regeneration has significant implications in various fields, including medicine, tissue engineering, and regenerative biology. Some potential applications of regeneration include:

1. Regenerative Medicine:
- Regeneration holds promise for repairing damaged tissues and organs, offering potential treatments for conditions such as spinal cord injuries, heart diseases, and organ failure.

2. Tissue Engineering:
- Regeneration principles are applied to develop engineered tissues and organs in the laboratory, aiming to replace damaged or diseased tissues.

3. Stem Cell Research:
- Understanding regeneration mechanisms can provide insights into
