Describe the structure of a neuron. Include the cell body, dendrites, and axon in your description. How does the structure of a
igomit [66]

Answer: A neuron has three main parts: dendrites, an axon, and a cell body or soma , which can be represented as the branches, roots and trunk of a tree, respectively. 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.

The axon (tree roots) is the output structure of the neuron; when a neuron wants to talk to another neuron, it sends an electrical message called an action potential throughout the entire axon.

The features of neurons help them to carry out their function efficiently:

they have a long fibre (axon) so they can carry messages up and down the body over long distances

in a stimulated neuron, an electrical nerve impulse passes along the axon

the axon is insulated by a fatty (myelin) sheath - the fatty sheath increases the speed of the nerve impulses along the neuron

at each end of the neuron are tiny branches (dendrons), which branch even further into dendrites - the dendrites receive incoming nerve impulses from other neurons

The organelle shown consists of a stack of flattened membranes.

What is the primary function of this organelle?

  • attaching amino acids to tRNA molecules
  • long-term storage of molecules in the cell
  • production of large and small ribosomal subunits
  • repackaging proteins for export from the cell

Answer:

  • repackaging proteins for export from the cell

Explanation:

The organelle consisting of a stack of flattened membranes is the Golgi apparatus.

The Golgi apparatus is like the packaging centre of the cell. It modifies, sorts, and packages proteins and from the endoplasmic reticulum to be stored in the cell or released outside the cell

DerKrebs [107]

Answer:

Cell membrane is considered as boundary of the cell.

Explanation:

Cell membrane is the boundary of the cell which is selectively permeable that allows the micro-nutrients, water and gases like oxygen and carbondioxide etc through the process of diffusion. When the water goes inside due to diffusion it is the indicator that there is less quantity of water present inside the cell as compared to the external environment, this phenomena is called hypertonic.
