Fission means splitting into two or more parts. In Unicellular organisms like Bacteria and Protozoan the cells split to make two or more new organisms.

What is the shrinkage of a tissue called?

Shrinkage of tissue by a decrease in either cell number or cell size is called atrophy (at′rō-fē). Atrophy may result from normal aging (senile atrophy) or from failure to use an organ or tissue (disuse atrophy).

What does the Bible mean by regeneration?

Spiritually, it means that God brings Christians to new life or “born again” from a previous state of separation from God and subjection to the decay of death (Ephesians 2:5). … Furthermore, there is the sense in which regeneration includes the concept “being born again” (John 3:3-8 and 1 Peter 1:3).

Regeneration is carried out by specialised cells. These cells form a mass of cells which undergo changes to form cells specialised in different functions. In hydra, if the body is cut into half, the lower part will develop head while the upper part will develop a new foot.

What type of cells Cannot regenerate?

What is another characteristic of stem cells?

Stem cells have unique abilities to self-renew and to recreate functional tissues. Stem cells have the ability to self-renew. Unlike muscle cells, blood cells, or nerve cells—which do not normally replicate— stem cells may replicate many times.

What is a blastema mean?

Regeneration BudBlastema, also called Regeneration Bud, in zoology, a mass of undifferentiated cells that has the capability to develop into an organ or an appendage. In lower vertebrates the blastema is particularly important in the regeneration of severed limbs.

What is regeneration and example?

Regeneration is different from reproduction. … Echinoderms (such as the sea star), crayfish, many reptiles, and amphibians exhibit remarkable examples of tissue regeneration. The case of autotomy, for example, serves as a defensive function as the animal detaches a limb or tail to avoid capture.

What is budding class 10th?

Budding is a form of asexual reproduction where a bud or outgrowth from the end or side of the parent organism emerges and develops into a new organism. … Usually, the protrusion stays attached to the primary organism for a while, before becoming free. The new organism is naturally genetically identical to the parent.

What is a regeneration area?

Urban regeneration involves the redevelopment of sites that are currently uninhabitable, creating areas where residential dwellings can be built. The impact of regeneration is often to make these areas desirable places to live and to provide homes that ease the pressure on limited UK property supply.
