A cell becomes a brain cell, or a neuron, through a process called neurogenesis, where stem cells differentiate into neural progenitor cells and then into neurons, influenced by specific genes and environmental signals. Similarly, a skin cell, or keratinocyte, arises from stem cells in the epidermis, where signals from surrounding cells and factors like growth factors drive the differentiation process. Both types of cells undergo specific gene expression changes that dictate their unique functions and characteristics. This differentiation is crucial for the development of specialized tissues in the body.

How do one cell become a brain cell ad the other a skin cell?
Cell differentiation occurs when a single fertilized egg divides and its cells begin to specialize into different types. This process is guided by gene expression, where specific genes are activated or silenced in response to various signals, such as chemical cues from surrounding cells. As a result, one cell may express genes that lead it to become a brain cell, while another cell may activate genes that guide it to become a skin cell. This specialization allows for the formation of diverse tissues and organs within an organism.
How do some cells become brain cells and others become skin cells when the DNA in all the cells is exactly the same in other words if the instructions are exactly the same how does one cell become a b?
Although all cells contain the same DNA, different genes are expressed in different cell types, leading to their specialization. This process is influenced by various factors, including chemical signals, the cell's environment, and transcription factors that activate or silence specific genes. For example, a cell destined to become a brain cell might express genes that promote neural development, while a skin cell expresses genes related to skin formation. This selective gene expression is what ultimately determines a cell's identity and function.
How is does one cell become a brain cell and another a skin cell?
The differentiation of cells into specific types, such as brain cells and skin cells, is driven by gene expression. While all cells in an organism contain the same DNA, different genes are activated or silenced in each cell type due to various signals and environmental factors. This process is influenced by transcription factors, epigenetic modifications, and signaling pathways that guide the development of stem cells into specialized cells. Ultimately, the unique combination of expressed genes determines the structure and function of each cell type.
Is the brain one cell?
No.
A brain stem cell only produces its own type of cell which type a stem cell is this brain stem cell?
Unipotent
Is it true that Humans are made of one single cell?
No. Humans are made of billions if not trillions of cells that work together to form all of the systems in your body such as skin, the brain, blood and organs. These cells also are not the same type of cell, for example, a skin cell differs from a red blood cell as well as a brain cell. But each person can be said to begin from one, single cell that results from the merging of ovum and sperm.
Do unicellular organisms have skin cells?
No First of all, a skin cell is not an organism on its own. It has to join other cells to form and organism. Second of all, a skin cell is only one cell. Multicellular organisms have more than one cell.
What is a basal cell and what is it's purpose?
A basal cell is a type of cell found in the innermost layer of the epidermis, the outermost layer of the skin. Its main purpose is to continually divide and differentiate to replenish skin cells that are lost through normal wear and tear. Basal cells play a critical role in maintaining the integrity and function of the skin.
What part of a cell acts as the skin?
no plant cells have cell wall and cell membrane animal cells have only cell membrane, or only cell wall (i don't remember)
How long does it take for one parent cell to become two daughter cells?
The process of cell division, where one parent cell divides to form two daughter cells, typically takes about 24 hours in human cells. This process involves multiple stages such as growth, DNA replication, and division.
What is an example of a nucleaus in science?
An example is like the nucleys is like the brain of the cell... If your body was one huge cell your brain would be the nucleus... see if that helps
Is a brain cell a organism?
No, a brain cell is not an organism. It is a fundamental unit of the nervous system that transmits information through electrical and chemical signals. Organisms are living beings that can carry out life processes on their own.
