|
During a cell’s development, it differentiates. How does differentiation occur?
|
|
a developing cell receives hormonal messages from endocrine glands that instruct the cell’s chromosomes
|
|
|
certain genes are turned on and other are turned off; this action produces adult cells that are specialized
|
|
|
a developing cell’s function is determined by the number of organelles it contains
|
|
|
as a cell mature, genes that are not necessary to its function are ejected out of the cell through active transport
|
Explanation:
Detailed explanation-1: -Cell differentiation is the process by which dividing cells change their functional or phenotypical type. All cells presumably derive from stem cells and obtain their functions as they mature. Cellular composition is often modeled as a hierarchical scheme with stem cells at the top of the hierarchy.
Detailed explanation-2: -The process of turning genes on and off is known as gene regulation. Gene regulation is an important part of normal development. Genes are turned on and off in different patterns during development to make a brain cell look and act different from a liver cell or a muscle cell, for example.
