Explain How Cells Specialize To Form Tissues And Organs?

cells specialize to form specific tisue and organs because all cells have the same DNA. stem cells can develop into every type of cell inside the body. … the cells are suppose to soak into the problem structure and slowly recreate the persons tissues.Apr 10 2014

Do tissues and organs have specialized cells?

An organ in a multicellular organism is a collection of tissues which are grouped in order to carry out a particular function. Each tissue in an organ consists of similar specialised cells.

How do cells develop into different tissues?

Body tissues grow by increasing the number of cells that make them up. … When cells become damaged or die the body makes new cells to replace them. This process is called cell division. One cell doubles by dividing into two.

How do cells become specialized?

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.

Why do cells need to become specialized?

Multicellular organisms need many different types of cells to carry out the same life processes. Each of these special types of cells has a different structure that helps it perform a specific function. … Cell differentiation is the process by which cells become specialized in order to perform different functions.

How is tissue different from a cell and an organ?

Cells are the smallest functional units of life. Tissues are groups of similar cells that have a common function. An organ is a structure that is composed of at least two or more tissue types and performs a specific set of functions for the body.

How does a cell become Specialised a level biology?

In order for a cell to become specialised a process called Differentiation occurs where unspecialised cells (called Stem Cells) produce cells with specialised structures.

What is a Specialised cell?

Specialised cells have a specific role to perform. Each specialised cell has a different job to do. They have special features that allow them to do these jobs. Muscle cells for example are held together in bundles which pull together to make muscles contract.

How does a stem cell become a specialized cell?

Stem cells produce new cells by dividing. In the right conditions these new cells can then continue to divide and differentiate into specialized cells. Stem cells can also divide to produce new stem cells to replace themselves.

Why do humans need Specialised cells and tissues in order to survive?

Multicellular organisms need specialized systems

The cells get oxygen and nutrients from this extracellular fluid and release waste products into it. Humans and other complex organisms have specialized systems that maintain the internal environment keeping it steady and able to provide for the needs of the cells.

What does cell specialization allow cells to do?

Cell specialization allow for cells to perform different functions that are essential to the functioning of an organism. … Multicellular organisms accomplish this by designating particular functions to particular cells and those cells work together to maintain homeostasis within a larger organism.

What is the role of specialized cells in the body?

Specialized cells allow for different types of tissues to exist in our organs so that the organs can perform different functions in our organ systems.

How are tissues and organs different quizlet?

What is the difference between tissues and organs? A tissue is a group of cells that perform the same function whereas organs is created by a specific type of tissue and made for a specific function.

What is the difference between and organ and an organ system?

An organ is a group of tissues that work together for the overall function of the organ and an organ system is a group of organs that work together to perform a specific function.

How do cells work together to create organs?

Different cells have different jobs to do. Each cell has a size and shape that is suited to its job. Cells that do the same job combine together to form body tissue such as muscle skin or bone tissue. Groups of different types of cells make up the organs in your body such as your heart liver or lungs.

How are Specialised cells formed in plants?

Stem Cells in Plants. Stem cells function as a source of new cells to grow or replace specialised tissues. To perform this function these cells must divide to renew themselves while some of their descendants eventually differentiate to build up new tissues.

What are cells Specialised structures and functions?

This means they are modified by size shape or function according to their purpose. Specialized cells make up tissues tissues make up organs and organs make up the systems that work together to make up our bodies. Nerve cells blood cells and reproductive cells are examples of specialized cells.

What are specialized cells and their functions?

Specialized cells perform specialized functions in multicellular organisms. Groups of specialized cells cooperate to form a tissue such as a muscle. Different tissues are in turn grouped together to form larger functional units called organs.

What is the order of cells tissues organs and organ systems?

The major levels of organization in the body from the simplest to the most complex are: atoms molecules organelles cells tissues organs organ systems and the human organism.

How do cells become specialized so they can have specific functions?

Cells undergo a process called differential gene expression. This process allows cells to become specialized as their structure determines their function. The process begins when a stimulus acts on an unspecialized cell (a cell that has the potential to become any cell in the body- multipotent stem cells).

Why are tissues specialized?

Cells make up tissues and tissues make up organs body systems and flesh. All these create our body. Each different specialized tissue has its own specific function in our body. Breakdown in specialized tissues may lead to disease and/or death.

What do tissues combine to form?

organs

Just as cells join together to form tissues different tissues join together to form organs. An organ is a structure made up of two or more tissues that work together to carry out a specific job.

What is the relationship between tissues and organs?

A group of cells working together is defined as a tissue and several tissues working together comprise an organ. The heart is used as an example of an organ which is made up from muscle and valve tissue.

What is the relationship between cells and tissues quizlet?

Cells make up tissues and tissues make up organ and organs make up organ systems which make up our body.

Can there be tissues organs and systems without cells?

Can be there be tissues organs anf system without cells? … No because a cell is the smallest structural and functional unit of an organism.

What are tissues?

Tissue is a group of cells that have similar structure and that function together as a unit. … There are four main tissue types in the body: epithelial connective muscle and nervous. Each is designed for specific functions.

How will you compare a cell from a tissue and an organ from organ system Brainly?

Cells of the same type make up tissues and different tissues together make an organ that has a destined function. Example: Stomach is an organ involved in digestion. Organ system: Organ system is made by different organs which together perform a one or more biological functions.

How do specialized cells or organs contribute to the function of plants and animals?

In multicellular animals and plants groups of specialised cells work together to create more complex structures: Organs are body parts that are made of several different types of tissue and carry out one or more particular functions.

What is cell specialization and why is it important?

Cell specialization also known as cell differentiation is the process by which generic cells change into specific cells meant to do certain tasks within the body. Cell specialization is most important in the development of embryos.

How are Specialised tissues generated from embryonic stem cells?

All of the cells in an embryo start off identical and undifferentiated. These cells are called embryonic stem cells and can become specialised to form any type of cell. They do this by switching genes on and off. … The embryonic stem cells receive signals from other cells so that they turn the correct genes on and off.

Which type of cells form new cells with specialized functions?

Stem cells provide new cells for the body as it grows and replace specialised cells that are damaged or lost. They have two unique properties that enable them to do this: They can divide over and over again to produce new cells.

Do tissues work together just as the cells do?

Within multicellular organisms tissues are organized communities of cells that work together to carry out a specific function. The exact role of a tissue in an organism depends on what types of cells it contains. … However the multiple cell types within a tissue don’t just have different functions.

Which of the following formed by a group of tissues and organs that are specialized for particular functions?

organ

The Group of tissues performing particular functions in the body is called an organ or an organ is a structure composed of at least two or more tissue types. Each tissue performs a specific function of the body. Several organs together constitute an organ system.
