Cell differentiation and specialisation
Karten in diesem Stapel (6)
- 1What is differentiation?The process by which a cell changes to become specialised for a job, developing different subcellular structures and becoming a different type of cell.
- 2When does differentiation occur?Mostly as the organism develops. The ability to differentiate is generally lost at an early stage (after they become specialised)
However, lots of plants cells don't ever lose the ability - 3How are sperm cells specialised?For reproduction- to get the male DNA to the female DNA
long tail, streamlined head- to help it swim
lots of mitochondria- supply energy
enzymes in head- break through egg cell membrane - 4How are nerve cells specialised?For rapid signalling- carrying electric signals around body
long- cover more distance
branched connections- connect to other nerve cells and create a network throughout the body - 5How are root hair cells specialised?For contracting quickly
long- more space to contract
lots of mitochondria- supply energy - 6How are phloem and xylem cells specialised?For transporting substances around the plant
Long, joined end to end- form tubes
hollow, few subcellular structure- stuff can flow through
