Cell differentiation

• Chromosomes carry genetic information in a molecule called DNA.
• Xylem vessels are specialised to transport water and dissolved minerals from the roots, up the plant.
• A type of cell division called mitosis ensures that when a cell divides each new cell produced has the same genetic information.

• Growing points are cells of the meristem specialised to produce new cells as they divide.
• Cells of the circulatory system are specialised to transport substances, defend the body, and regulate temperature.
• Cells of the meristem are specialised to produce new cells as they divide.
• Cells of the reproductive system are specialised to bring about fertilisation to produce new offspring.
• Cells of the muscular system are specialised to bring about movement.
• Specialised cells in animals are cells of the circulatory system, excretory system, muscular system, nervous system, respiratory system, and reproductive system.
• Cells of the spongy mesophyll are specialised to allow gases to circulate for the exchange of gases between the leaf and the environment, carry out some photosynthesis, and defend the body against pathogens.
• Cells of the phloem sieve tubes are specialised to transport products of photosynthesis, including sugars and amino acids, from the leaf to where they are needed.
• Cells of the companion cells are specialised to provide the energy required for transporting substances in sieve tubes.
• Cells of the nervous system are specialised to respond to internal and external stimuli and conditions, carry messages for the body, and work as a coordinated whole.
• Cells of the respiratory system are specialised to deliver oxygen for respiration and remove waste.
• Cells of the skeletal system are specialised to bring about movement, support and protect internal structures, produce blood cells, store and release calcium.
• Cells of the xylem xylem vessels are specialised to transport water and dissolved minerals from the roots, up the plant.
• Cells of the leaf are specialised to carry out photosynthesis.
• Cells of the excretory system are specialised to remove waste products and unwanted substances, and regulate the water content of the body.
• Cells of the guard cells are specialised to open and close to control the exchange of gases – carbon dioxide, water vapour and oxygen.
• Cells of the leaf palisade mesophyll are specialised to carry out photosynthesis.
• Cells of the xylem xylem vessels are specialised to transport water and
