Cell Differentistion and Specialisation Flashcards
A specialised cell
A cell that performs a specific function
Cell differentiation
The process by which a cell changes to become specialised job
Function of sperm cell
To get the male DNA to the female DNA
Structure of sperm cells
Long tail and streamlined head to help swim to the egg cell
A lot of mitochondria to provide energy to get to the egg
Enzymes in the head to digest through the egg cell membrane
Function of nerve cells
To carry electrical signals from one part of the body to another.
Structure of nerve cells
Long to carry more distance
Branched connections at the end to connect to other nerve cells
Function of muscle cells
To contract quickly
Structure of muscle cells
Long so they have space to contract
Lots of mitochondria for energy to contract
Function of root hair cells
To absorb water and minerals
Structure of root hair cells
Long hair is to give the plants a big surface area
Function of phloem and xylem cells
To transport substances such as food and water around plants
Structure of xylem cells
Hollow in the centre so substances can flow through it
Structure of phloem cells
Very few sub cellular structures so substances can flow through it
