Growth cones are defined as
A)the influences of neighboring cells on differentiation.
B)attractant chemicals that guide axon growth and inhibit meiosis.
C)death genes that are expressed when a cell "decides" to die, leading to the formation of exact replacements for that cell.
D)swollen ends of axons and dendrites that help the branch reach its synaptic target.

Quizplus · Accepted Answer

Growth cones are the swollen ends of axons and dendrites that play a crucial role in directing the growth of neuronal processes towards their targets during development. They respond to guidance cues such as attractants or repellents, and help the extending branch make contact with its target cell.
