Question

True or False. A. Eukaryotes cannot be viewed with a compound light microscope.

B. Eukaryotes have membrane-bound organelles that can be seen under low or high-dry powered objectives.

C. Prokaryotes can be seen easily using a wet mount and don't require staining because of their large size.

D. Prokaryotes are larger than eukaryotes but require staining view.

E. Prokaryotes have membrane-bound organelles but their thick cell wall prohibits this observation.

Answer 1

A. Eukaryotes cannot be viewed with a compound light microscope. False

Eukaryotic cells can be viewed under a compound light microscope. under light microscope one can view cell walls, vacuoles, cytoplasm, chloroplasts, nucleus and cell membrane.

B. Eukaryotes have membrane-bound organelles that can be seen under low or high-dry powered objectives. False

Light microscope have a limited magnification of about 2000x, which is not sufficient to see many tiny membrane bound organelles like ribosomes, endoplasmic reticulum, lysosomes, centrioles, golgi bodies. They can be visualized only under an electron microscope. They use a beam of electrons to illuminate a specimen and produce an image. The magnification is about 10,000,000X.

C.Prokaryotes can be seen easily using a wet mount and don't require staining because of their large size. False

Yes, Prokaryotes can bee seen easily usinf a wet mount without any staining procedure. But on the size front Eukaryotic cells are generally much larger than prokaryotic ones.

Prokaryotic specimens can be prepared in either wet mount or dry mount depends on the type of specimen being viewed and the purpose for preparing the slide. When making a quick preparation of a specimen, the wet mount is ideal.

When more detail is required about the specimen, a dry mount of the specimen is recommended. A dry mount allows the user to heat-fix the specimen to the slide. Then different dyes that stain the structures inside the cell can be added to further examine the cell.

D. Prokaryotes are larger than eukaryotes but require staining view. False

Prokaryotic cells are significantly smaller (0.1 to 5 um in diameter) than Eukaryotic cells, which have diameter ranging from 10-100 um. The prokaryotes can be viewed under light microscope without any staining procedure.

E. Prokaryotes have membrane-bound organelles but their thick cell wall prohibits this observation. False

Prokaryotes does not contain any membrane bound organells like neuleus or mitochondria. The gram positive group of bacteria have thick cell wall, however that do not interfere with observation.
