Select the correct answer to
complete the table provided. (A) Round, biconcave cells that
have large surface areas with no nuclei. (B) Long cells, with branching
dendrites that connect to other neurons. (C) Short, spherical cells that
have large nuclei. (D) Filamentous cells that contract
and relax.
In biology, structure and function
are closely related concepts. The structure of a cell or its
components often relate to its function. Cells that have specific structures
and functions are said to be specialized. A sperm cell is an example of a
specialized cell. Its long tail allows it to swim
toward the egg in order to fertilize it. Another type of specialized cell is
a neuron, whose function is to transmit electrical signals from one part of the body
to another. To do this, these cells can be very
long with multiple branching dendrites to connect to other neurons.
Therefore, the option that best
describes the structure of a neuron is given by answer choice (B): long cells, with
branching dendrites that connect to other neurons.
