Give examples of Specialised Cells; |
Sperm Cells - function is to get the male DNA to the female DNA. It has a long tail+streamlined head to help it swim. Moreover, it carries enzymes to digest through the egg cell membrane. Nerve Cells - function of nerve cells is to carry electrical signals from one part of body to another. The cells are long to cover distance and have branched connections to connected to other nerve cells and form a network throughout the body. Muscle Cells - the function is to contract quickly, cells long and contain lots of Mitochondria to generate energy needed for contraction. |
