4 - Cell Differentiation And Specialisation Flashcards
What is differentiation
It is the process by which a cell changes to become specialised for its job.
When a cell changes, what does it develop
It develops different subcellular structures and turn into different types of cells.
When does differentiation occur the most
When an organism develops.
What is the difference between animal and plant cells differentiation ability
Animal cells lose to ability at an early stage whereas plant cells don’t ever lose this ability
What is an undifferentiated cell
It is called a stem cell
What are sperm cells specialised for
They are specialised for reproduction
What is the function of a sperm cell
It’s function is to get the Male DNA to the female DNA
What are the features of a sperm cell to help it swim to the egg
It has a long tail and a streamlined head
What does the sperm cell have a lot of
It has a lot of mitochondria to provide the energy needed
What is in the head of a sperm cell
It has enzymes in its head to digest through the cell membrane
What are nerve cells specialised in
They are specialised for rapid signalling
What is the function of nerve cells
It’s function is to carry electrical signals from one part of the body to another
Why are nerve cells long
They are long to cover more distance
How do nerve cells get along the body
They are long and have branched connections at their end to connect to other nerve cells and form a network throughout the body
What are muscle cells specialised for
Muscle cells are specialised for contraction
