Answer:
Desmosomes
Explanation:
The plates holding cells together in tissues are called desmosomes. Desmosomes are the tissue basement. They hold the cells together. So the tissues retain in a definite shape. These are the intermediate filaments and make a net-like structure. These are made up of keratins. It is a structural protein found exclusively in nails and hairs. The desmosomes are 3 types- spot desmosomes, belt desmosomes, and hemidesmosomes. Desmosomes are the connection between 2 cells.
To be more correct, the left side is alkali metals

Answer:
Electron microscopes use a beam of electrons instead of beams or rays of light. Living cells cannot be observed using an electron microscope because samples are placed in a vacuum. ... the scanning electron microscope (SEM) has a large depth of field so can be used to examine the surface structure of specimens.
