Cell differentiation and specialisation Flashcards
What is a specialised cell?
Cells that carrys out a specific function
What happens as cells change?
Develop different subcellular structures
When can most animal cells only differentiate?
in early stages of there life
when can plants differentiate?
Through their whole life
Why do some cells differentiate during animals older ages?
For repairing or replacing cells
What are some different types of specialised cells?
sperm cells, nerve cells, muscle cells, root hair cells, phloem/xylem cells
Sperm cells adaptations
Tails to help them swim, a lot of mitochondria which provides energy for swimming
Nerve cells
Long to cover more distance of the body, branches to connect to other nerve cells
Muscle cells
Long so they have space to contract, lots of mitochondria which provides energy
Root hair cells
Long hairs which stick out of the soil, big surface area
Phloem and xylem cells
To form the tubes they are long and joined end to end, xylem cells are hollow and phloem cells have very few subcellular structures, lot’s of space to flow through them
