Answer:

Different types of cells shapes effect the function of the cells. Muscle cells are shaped like they are because they have to perform a certain function to meet the critia of what the body is telling it what to do.

Explanation:

Skeletal muscle cells are located in a bundle of linear fibers. These are thin chains of the proteins actin and myosin that cause muscle contraction. The elongated shape of muscle cells allows contractile proteins to place themselves in an overlapping pattern that allows muscle flexion.

Sarcomere

Explanation:

A myofibril or muscle fiber under an electron microscope shows alternate light band and dark bands.  These bands give the skeletal muscle and cardiac muscle a striated appearance. The light band is called the I- band or isotropic band, and the dark band is known as A- band or anisotropic band. In the center of the I-band Z-line is present. It is discovered from a German term Zwischenscheibe (between the disc). The portion of myofibril between one Z-line to the next Z-line is called sarcomere.

The plant cells communicate across cell walls through Plasmodesmata.

how do plant cells communicate across cell walls?

  • Between tiny channels woven through the walls of neighboring plant cells, plant cells can communicate with one another through channels referred to as plasmodesmata.
  • These channels enable chemicals to move freely between cells, allowing plants to grow regularly and form tissues and organs.
  • However, plasmodesmata also act as entryways that viruses can employ to infect an increasing number of cells.
  • Given these advantages and disadvantages, plants must balance the permeability of their plasmodesmata in order to move materials from one cell to another while preventing the spread of infection.
