Cell differentiation and Specialisation Flashcards
What is cell differentiation?
Cell differentiation is a process in which cells change to become specialised for its job.
How are sperm cells specialised?
Sperm cells has a long tail and streamlined head that helps it swim faster. It also has a lot of mitochondria which supplies it with the energy it needs to swim.
How are nerve cells specialised?
Nerve cells are long and have branched connection at their ends that connect to other nerve cells and makes a network around the body. They are long in order to allow signals to travel faster and cover more space.
How are muscle cells specialised?
Muscle cells are long and contain lots of mitochondria which allows them to contract faster.
How are root hair cells specialised?
They grow out into long hairs which gives them a larger surface area, therefore, allowing them to absorb a lot more water.
How are Phloem and Xylem cells specialised?
Xylem cells are hollow in the centre and phloem cells have very few sub-cellular structures, so that substances can flow through them.
