streamlined head long tail for swimming. many mitochondria release energy for movement. top of head( acrosome ) has digestive enzymesbreakdown outer layers of membrane of egg cell
How are nerve cells specialised?
axonlong so impulses able carried long distances.dendrites able form connections with other nerve cells. nerve endings have mitochondria release energy make neurotransmitters so impulse pass from one cell to another.
How are muscle cells specialised?
special proteinsslide over each other so muscle can contract. lots of mitochondria to release energy for contraction. store glycogen that used in respiration by mitochondria
