what is the difference between determination and differentiation? determination is the process in
which embryonic stem cells commit to
one specialized function. differentiation is the process in which cells develop their specialized shapes and functions.
What is differentiation and determination?
The main difference between cell determination and cell differentiation is that the cell determination is the
assignment of the fate of the cells
whereas, the cell differentiation is the morphological modification of the cells to perform the assigned function.
What is the relationship between determination and differentiation?
Explanation: Once a committed cell begins to develop specialized functions, it is known as differentiation. Before a cell differentiates, it
makes a commitment to a certain cell type
, first by specification, which is reversible, and then by determination, which is irreversible.
What comes first cell determination and differentiation?
Primary Factors Influencing Cell Differentiation
Gene Structure
– This is the most important factor when it comes to cell differentiation. Each of the viable genes contains important information that determine the cell type and physical attributes of the animal (host).
What is the difference between differentiation and development?
Plant development comprises both
growth and differentiation
. Over time and space, growth and differentiation lead to the formation of an organism having metabolic and structural complexity. Development encompasses the activities resulting from growth and differentiation.
What triggers cell determination?
Cell determination usually takes place as a result of
inductive signaling between nearby cells
. … Differential gene expression refers to the ability of a given unspecialized cell to express different genes and therefore produce different proteins and structures found within that final specialized cell.
What is the process of cell determination?
The process in which
a previously undifferentiated cell is already programmed to become a specific cell type by following a specified path towards cell differentiation
. Cell determination is influenced by the action of the extracellular environment and the contents of the cell’s genome.
What is determination in development?
In classical embryology, the term ‘determination’ was used to
describe the process by which a region of the embryo became committed to form a particular part of the body
and it was understood that there was a particular stage of development at which determination occurred with respect to each decision
1 – 3
.
What is the most significant cause of cell differentiation in a multicellular organism?
Usually, the
cell changes to
a more specialized type. Differentiation occurs numerous times during the development of a multicellular organism as it changes from a simple zygote to a complex system of tissues and cell types. … Some differentiation occurs in response to antigen exposure.
What are the two main influencing factors that affect cell differentiation briefly explain each?
Factors involved in triggering cell differentiation include
cell signaling, environmental influences and the level of development of the organism
. Basic cell differentiation occurs after a sperm cell fertilizes an egg and the resulting zygote reaches a certain size.
What is an example of cell differentiation?
An example of cell differentiation is
the development of a single-celled zygote into a multicellular embryo that further develops into a more complex multisystem of distinct cell types of a fetus
. … A cell that underwent differentiation is described as differentiated.
What happens after cell differentiation?
The final stage of differentiation often involves
the formation of several types of differentiated cells from one precursor or stem cell population
. Terminal differentiation occurs not only in embryonic development but also in many tissues in postnatal life.
What are the advantages of cell differentiation?
The main advantage of cell differentiation is that
cells become specialised to perform specific functions efficiently
. E.g. the cell loses its protoplasm and develops a lignified cell wall to facilitate the transport of water by tracheary elements of the xylem.
When it comes to human development What does the term differentiation mean?
In a developing organism, differentiation implies
increasing structural and functional complexity
. One kind of differentiation concerns changes in gross shape and organization. Such activities, related to molding the body and its integral parts into form and pattern, comprise the processes called morphogenesis.
What are the processes of growth and differentiation?
Growth means increase in size due to an increase of existing structural (and functional) units. Differentiation is
a process whereby a relatively simple system is changed into a more complicated one
.
What occurs in cell differentiation and morphogenesis?
Differentiation refers to how cells become specialized
, whereas morphogenesis refers to the development of the forms of living organisms.
