Projections in cells, such as axons and dendrites in neurons, play a crucial role in facilitating communication and signaling. These extensions allow cells to connect and transmit information over distances, enabling complex processes such as reflexes and cognitive functions. The structure and organization of these projections are directly linked to the efficiency and speed of signal transmission, thereby influencing overall cell function and intercellular interactions. Understanding these projections helps elucidate how cells coordinate activities within tissues and systems.
It is the basic building block of life
The modern version of these cells is called a virus.
No.
Muscle cells have visible projections called myofibrils, red blood cells lack visible projections due to their biconcave disc shape, and sperm cells have a visible projection called a flagellum which helps in motility.

Its structure determines the function it has. For example, red blood cells are biconcave discs, kind of thinner in the middle and thicker around the outside. As it turns out this is the ideal surface area to volume ratio for exchanging things between the inside of the cell and outside. When you consider that the function of red blood cells to carry oxygen to the cells of the body the structure of the RBC is ideally suited to its function.
