Question

organisms which can. be seen only under a microscope​

Answer 1

Explanation:

Since the introduction of electron microscopes in the 1930s, scanning electron microscopy (SEM) has developed into a critical tool within numerous different research fields, spanning everything from materials science, to forensics, to industrial manufacturing, and even to the life sciences.

As soon as microscopic information about the surface or near-surface region of a specimen is needed, SEM becomes a necessary tool. For that reason, the method finds applications in nearly every branch of science, technology and industry.

Answer 2

Answer:

Unicellular

Explanation:

• An organism can only be seen under a microscope. Bacteria, amoeba, algae, and fungi are examples of microorganisms. Viruses are not living beings, but they are occasionally categorized as microbes.
• The majority of unicellular creatures are tiny in size and so categorized as microorganisms; for example, phytoplankton and protozoa range in size from around 0.001 mm to about 0.25 mm.

• The majority of multicellular creatures and vertebrates can be seen with the naked eye, implying that they can be observed without the need for a microscope.
