Which of the following types of cells undergo regeneration?

Stem cells are the type of cells that undergo regeneration.

Stem cells are unspecialized cells that have the ability to divide and differentiate into various types of cells in the body, depending on the signals they receive from their environment. Stem cells can be found in various tissues and organs in the body, such as bone marrow, skin, and the digestive system.

Stem cells play an important role in regeneration because they have the ability to replace or repair damaged tissues and organs by differentiating into the specific cell types needed for the regeneration process. This makes stem cells a promising area of research for the development of new therapies for a wide range of diseases and conditions, including heart disease, diabetes, and neurological disorders.

Onion cells, plant cells, and leaf cells do not undergo regeneration to the same extent as stem cells. However, some plant cells are capable of regeneration under certain conditions, such as when a plant is wounded or injured. In these cases, specialized cells called meristematic cells can differentiate into different cell types to repair the damaged tissue.
