Cell Specialisation Flashcards

All 6 cards in this deck

What is a specialised cell?: A cell whose structure and sub-cellular structures allow it to carry out one particular function.
How is a sperm cell specialised for its function?: It has a tail to swim to the egg, many mitochondria to release the energy for swimming, and enzymes in the head to digest the egg's membrane.
How is a nerve cell specialised for its function?: It is very long, so impulses are carried over long distances, and has branched endings to connect to other cells.
How is a muscle cell specialised for its function?: It contains long protein fibres that can contract (shorten) and many mitochondria to release the energy needed.
What does it suggest about a cell if it contains a large number of mitochondria?: The cell is very active and needs a lot of energy released by aerobic respiration.
True or false? Every cell in a multicellular organism contains exactly the same sub-cellular structures.: False. Specialised cells have different sub-cellular structures suited to their particular function.
