Total questions: 13
Worksheet time: 7mins
Cells differentiate to perform different functions because
all genes are turned on inside that cell
all genes are turned off inside that cell
different genes are turned on inside that cell
different genes are turned on or off inside that cell
During the process of differentiation
all sections of DNA are activated to determine the structure of a body cell
ONLY ONE section of DNA are deactivated to determine the structure of a body cell
only specific sections of DNA sequence are activated to determine the structure and functions of a body cell
Unspecialized cells in our body that has the ability to differentiate into different types of cells are called
specialized cells
differentiated cells
nerve cells
stem cells
Which best explains why muscle cells are different from blood cells?
Muscle cells are produced by the brain, but blood cells are produced by the heart.
Different genes are activated in muscle cells than in blood cells.
Muscles cells experience different environmental influences than blood cells.
A mutation occurs during the development of muscle cells but not in blood cells.
What is cell differentiation?
Process by which cells produce more cells
Process by which cells become specialized
Process by which cells become unspecialized
Process by which cells die
Which of the following best describes Specialized Cells?
They can divide rapidly
They are identical to all other cells in the organism
They have specific structures and functions
They are only found in cancerous cells
Cell differentiation is critical during embryonic development. The process of cell differentiation results in the production of many different kinds of specialized cells. This process is most directly influenced by
DNA
Lipids
Carbohydrates
ATP
What is the function of red blood cells?
Help to digest your food.
Help you breathe.
Provide nutrients to your organs.
Carry oxygen throughout your body.
What is the function of nerve cells?
Allow for gas exchange to happen.
Transport oxygen throughout the body.
Control DNA expression.
Transmit electrical signals to different parts of the body.
Muscle cells are long, thin fibers.
This statement describes a STRUCTURE.
This statement describes a FUNCTION.
Muscle cells become shorter and thicker when they contract the muscle.
This statement describes a STRUCTURE.
This statement describes a FUNCTION.
Each of the following is an example of a specialized cell in animals except
stem cells
muscle cells
nerve cells
blood cells
