Cell Differentiation & Specialisation Flashcards
What is cell differentiation & specialisation?
Process by which cell change to become specialised is called differentiation
When cells change what do they develop?
Different subcellular structures
What does turning into a different type of cell allow?
Allows them to do a specific function
What stage do animal cells differentiate?
Early stage of animal life
When does differentiation occur?
When an organism develops
How long can differentiation happen in plant cells?
Their whole lives
What are differentiated cells mainly used for in adult animals?
For repairing and replacing cells
What are differentiated cells mainly used for in adult animals?
For repairing and replacing cells
What are undifferentiated cells called?
Stem cells
What are examples of specialised cells?
Sperm cell
Nerve cell
Muscle cell
Root hair cell
Phloem cell
Xylem cell
What do sperm cells do?
Takes make DNA to egg
What do nerve cells do and involve?
Carry electrical signals around body and are long to cover distance and branches to connect to other nerves
What do the muscle cells do and involve?
Contract
They are long so they can contract and have lots of mitochondria for energy to contract
What do root hair cells do and involve?
Absorbs water and minerals
Long so they can stick out of soil and have big surface for absorbing water and minerals
What does the phloem cell do and involve?
Transports food
It had few subcellular and has lots of space inside for stuff to flow in
