What happens to a cell when they undergo differentiation?
Terms in this set (12) Differentiation is the process by which cells change in structure and become capable of carrying out specialized functions. The instructions coded into the cell’s DNA determines its future, and the active DNA directs the cell.
What happens to cells when they undergo differentation?
Cell differentiation is defined as a biological process in which cells gain specialised functions in the body and change from one cell type to another. Everything in the body nails, hairs, organs, and even blood is made up of cells. It is by the process of cell differentiation, that embryonic cells are changed to specialized cells.

What effects does cell differentiation have?
There are few instances leading to cell differentiation:
- Regular turnover of cells (blood cells in mature entities)
- Immature entity growing into an adult
- Damaged tissues undergoing repair when special cells are to be substituted
- Influence of cytoplasm
- Interaction between cells
- Hormones
What happens during cell differentiation quizlet?
As cells differentiate, they become different from one another. They also form groups made of other, similarly specialized cells. These groups then form tissues and organs. Through mitosis and differentiation, the single cell becomes an organism with specialized structures.

Where does cell differentiation happen?
Differentiation from visibly undifferentiated precursor cells occurs during embryonic development, during metamorphosis of larval forms, and following the separation of parts in asexual reproduction. It also takes place in adult organisms during the renewal of tissues and the regeneration of missing parts.
What is meant by process of differentiation?
The loss of ability to divide by taking up a permanent shape, size and function is called differentiation. Cells develop into tissues and organs with the help of differentiation.
What is the result of differentiation?
Differentiation is a process of finding a function that outputs the rate of change of one variable with respect to another variable.
What is cell differentiation simple definition?
Cell differentiation refers to the normal process by which a less specialized cell goes through development and maturation in order to become more distinct in terms of form and function. It is the process in which a cell changes into another cell type.
What happens during the process of differentiation astronomy?
When planets begin to melt, the materials in them begin to separate from one another. The heaviest materials, such as metallic iron, sink to form cores. Low-density magmas rise, forming crusts. This process is called differentiation.
Do differentiated cells divide?
A few types of differentiated cells never divide again, but most cells are able to resume proliferation as required to replace cells that have been lost as a result of injury or cell death. In addition, some cells divide continuously throughout life to replace cells that have a high rate of turnover in adult animals.
What is cell differentiation simple definition?
Cell differentiation refers to the normal process by which a less specialized cell goes through development and maturation in order to become more distinct in terms of form and function. It is the process in which a cell changes into another cell type.
What is cell differentiation GCSE?
Cell differentiation is an important process by which a cell changes to become specialised. Cells that have not differentiated are therefore unspecialised. As an organism develops, cells differentiate to form different types of cells.
What would happen without cell differentiation?
Without cell division, long-term tissue survival would be impossible. Inside every tissue, cells are constantly replenishing themselves through the process of division, although the rate of turnover may vary widely between different cell types in the same tissue.
How does differentiation occur in a cell?
Cell differentiation is how generic embryonic cells become specialized cells. This occurs through a process called gene expression. Gene expression is the specific combination of genes that are turned on or off ( expressed or repressed ), and this is what dictates how a cell functions.
What is cell differentiation?
Let's review. Cell differentiation is the process of cells developing and specializing from generic embryonic cells. Cell differentiation creates all of the different structures in your body, like muscles, bones and organs. Cell differentiation also produces the vast number of organisms on Earth and allows for many different cell structures ...
What is signaling in biology?
Signaling molecules are molecules that bring messages to cells that help the cell know which activities and processes to perform. Signaling molecules carry a message to a cell receptor, which interprets the message through a signal transduction pathway.
Why is differentiation important?
Importance of Cell Differentiation. As your cells develop and differentiate, they become quite different in structure and function. Once this differentiation begins, a cell is bound to that fate and must continue down its path of differentiation .
What is the role of gene expression in cell differentiation?
Gene Expression Regulates Cell Differentiation. Everything in your body is made up of cells: your hair, fingernails, bones, muscles, organs and even blood. All of these cells contain the same genetic material, or DNA, and this genetic material is what makes you a unique individual - it's different from everyone else's DNA.
Why do cells need different structures?
Cells need to have different structures because they have different functions. A sperm cell has a function that is very different from a skin cell or a liver cell. If a sperm cell were not shaped the way it is, it would have a very difficult time swimming to an egg to fertilize it.
Why does gene expression occur?
Gene expression occurs because of certain signals in your body, both inside and outside of your cells. Cell differentiation occurs during multiple stages of development. During cell differentiation, the cell size and shape changes dramatically, as does its ability to respond to signaling molecules. Signaling molecules are molecules ...
Why is cell differentiation important?
This is because of the fact that it causes changes in size, shape, metabolic activities as well as signal responsiveness of cells.
What happens during the final phase of cell differentiation?
During the final phase of cell differentiation, there is formation of several types of differentiated cells from one population of stem cells of the precursor. Here, terminal differentiation occurs both in embryonic development as well as in tissues during postnatal life.
What happens when an egg is fertilized?
As soon as the egg is fertilized, cell multiplication is initiated resulting in the formation of a sphere of cells known as the blastocyst. It's this sphere of cells that attach to the uterine wall and continues to differentiate. As the blastocyst differentiates, it divides and specializes to form a zygote that attaches to the womb for nutrients. ...
What is a cell capable of differentiation?
A cell capable of differentiating into any type of cell is known as "totipotent". For mammals, totipotent includes the zygote and products of the first few cell divisions. There are also certain types of cells that can differentiate into many types of cells.
What is the name of the cell that divides to produce new differentiated generations?
These cells are known as "pluripotent" or stem cells in animals (meristemic cells in higher plants). While this type of cell can divide to produce new differentiated generations, they retain the ability to divide and maintain the stem cell population making them some of the most important cells.
Why are stem cells important?
As mentioned earlier, stem cells are important in that they can develop to any cell type. This makes them very special in that they can differentiate and be used for given treatment purposes. A good example of this is with cells among the older adults. In older years, many of the cells experience wear and tear.
What determines the type of cell that will be created?
The regions (genes) that are expressed determine the type of cell that will be created. While the different types of cells that are formed contain the same DNA, it's the expression of different genes that results in different types of cells. This is to say that not all genes are expressed during differentiation.
Process and Steps of Cell Differentiation
- In Animals
After the process of fertilization in animals, a single-celled organism called the zygote is formed. The zygote is totipotent, and will eventually become an entire organism. Even the largest animal on Earth, the blue whale, starts as a single cell. The complex tissues and organ systems, which a…

Primary Factors Influencing Cell Differentiation
- Once the female egg has been fertilized, thecells formed after cell division contain DNA that is identical. That is, theDNA in all the cells will be identical. However, different regions of achromosome(DNA is wound in to a chromosome) code for different functions andcell type. Here, it's only the regions that are required to perform a givenfunction that are expressed in each cell. …
