- Cell Differentiation And Specialisation
- Cells Differentiate To Become Specialised
- Differentiation Is A Process By Which Cells Change To Become Specialised For Their Job
- As Cells Change, They Develop Different Subcellular Structures And Turn Into Different Types Of Cells
- This Allows Them T Carry Out Specific Functons
- Most Differentiation Occurs As Organisms Develop
- In Most Animal Cells, The Ability To Differentiate Is Lost At An Early Stage After Becoming Specialised
- Many Plant Cells Don't Lose The Ability To Differentiate
- Cells That Differentiate In Mature Animals Are Mainly Used For Repairing And Replacing Celss
- Examples: Skin Cells Blood Cells
- Some Cells Are Undifferentia-ted Cells
- Called Stem Cells
- Nerve Cells
- Specialised For Rapid Signalling
- Function Is To Carry Electrical Signals From 1 Part Of The Body To Another
- Have Branched Connections At Either Ends To Connect To Other Nerve Cells And Form A Network Through The Body
- Sperm Cells
- Function Is To Get The Male DNA To The Female DNA
- Have Long Tails And Streamlined Heads To Help Them Swim To The Egg
- There Are Many Mitochondria In The Cell To Provide The Energy Needed
- Carries Enzymes In Its Head To Digest Through The Egg Cell Membrane
- Specialised For Reproduction
- Muscle Cells
- Specialised For Contraction
- Function Is To Contract Quickly
- These Cells Are Long
- So They Have Space To Contract
- Contain Many Mitochondria To Generate Energy Needed For Contraction
- Phloem And Xylem Cells
- Specialised For Transporting Substances
- Form Phloem And Xylem Tubes, Which Transport Food And Water Around Plants
- To Form The Tubes, The Cells Are Long And Joined End To End
- Xylem Cels Are Hollow In The Centre And Phloem Cells Have Very Few Subcellular Structures, So That Stuff Can Flow Through
- Root Hair Cells
- Cells On The Surface Of Plant Roots
- Grow Into Long Hairs That Stick Out Into The Soil
- Gives The Plant A Big Surface Area For Absorbing Water And Mineral Ions From The Soil
- Specialised For Absorbing Water And Minerals
- Cells On The Surface Of Plant Roots
- Cells Differentiate To Become Specialised
