What is the advantage of using oil-immersion objective lenses when viewing small specimens?

Answer 1

The low power objective is useful for allowing you to focus your lens on the object that you wish to study without too much difficulty. Then it should be possible to simply switch to a higher power objective lens without having to do more than make a small adjustment to the fine focus knob. Another advantage of the lower power lenses is to allow scanning for something that may be of interest, without needing to examine each field in minute detail when the organism/organelle of interest is not present. When you see something of potential interest, you can then switch to a higher power lens.

Answer 2

As protozoa are rather large on the micro scale, one does not need oil immersion lenses or high power. analogy- one does not need extreme lens speed or shutter speeds to photograph large stationary objects such as Bridges or buildings! moving targets are another matter.

Answer 3

You are working on a workbook called symbolis, aren't you? I don't know.

Answer 4

what advantage does the low power objective have over oil immersion in viewing fungi

Answer 5

Fungi have large cells and are better viewed structurally under a low light, which also allows better depth of vision and can use lower light.

Answer 6

Live fungal cells can be observed for a long time.
