dendrites are like ____
A
Popsicle sticks
B
shoe laces
C
a ahir brush
D
tree branches
Explanation: 

Detailed explanation-1: -A dendrite (tree branch) is where a neuron receives input from other cells. Dendrites branch as they move towards their tips, just like tree branches do, and they even have leaf-like structures on them called spines.

Detailed explanation-2: -The Dendrites Dendrites are appendages that are designed to receive communications from other cells. They resemble a tree-like structure, forming projections that become stimulated by other neurons and conduct the electrochemical charge to the cell body (or, more rarely, directly to the axons).

Detailed explanation-3: -Dendrites look like the branches of a tree and receive messages for the cell. Neurons communicate with each other by sending chemicals, called neurotransmitters, across a tiny space, called a synapse, between the axons and dendrites of adjacent neurons.

Detailed explanation-4: -The word “dendrite” is Greek for “tree", and reflects the appearance of the dendrites. Dendrites resemble the branches of a tree as they extend from the soma. The dendrites for a single neuron are collectively called the dendritic tree, and each branch is called a dendritic branch.

Detailed explanation-5: -Dendrites have specialized structures including spines, which are the main excitatory synaptic sites that are not found in axons. Unlike axons, dendrites have tapering processes such that distal branches have smaller diameters than proximal ones.
