It follows that no other cell in the body performs a neuron's exact functions.
<h3>
What about neurons?</h3>
- Information is transmitted via neurons.
- They communicate between various brain regions and between the brain and the rest of the nervous system through electrical impulses and chemical signals.
- The basic building blocks of the brain and nervous system are neurons (also known as neurones or nerve cells).
- The cells known as neurons are responsible for receiving sensory data from the outside world, sending commands to our muscles, and converting and relaying electrical signals at various points along the road.
- The bulk of neurons in vertebrates are found in the central nervous system, however some are found in peripheral ganglia and many sensory neurons are found in sensory organs like the retina and ear.
- A neuron is made up of a cell body, which includes a nucleus and cytoplasm, from which long, thin portions that resemble hair grow.
- The neuron's lone long component, known as the axon, is responsible for carrying nerve impulses to various body areas.
- Dendrites are the short, branching components of the neuron.

Nucleus and ribosome are the correct answers.
<h2>B) option is correct </h2>
Explanation:
- Mosses are waxy little plants with no leaves and no stem that use each other to stay upright, their grouping helps them retain water in the area
- A waxy covering across their bodies helps keep water from evaporating and are usually found in moist areas out of the direct sunlight
- In mosses, gametophyte (1N multicellular adult plant) is the dominant portion
- When top of the female gametophyte plant is sectioned longitudinally and examined with a microscope, several egg-producing structures called archegonia are present, two archegonia each produces one 1N egg cell
- The egg is clearly visible in the archegonium at the left and only part of the egg cell is visible in the archegonium on the right
- Once sperm have been splashed to the female plants, sperm swim into the archegonium and fuse with the egg, the process is called fertilization
- A single 2N cell called the zygote (or fertilized egg) is formed
- Zygote further undergoes mitosis many times to eventually form a multicellular 2N plant called the sporophyte
