Why is it difficult to see in focus on all parts of a large organism under high magnification?

Light microscopes require light to be reflected from the base of the microscope, up through the organism, and into the eye. If an object you are trying to view is too thick, the light will not pass through the specimen as easily. Also, thicker objects cause more light to refract so that less of it passes through the pinholes, thus making it difficult to focus on.
Here's a helpful website on microscope optics:

Confocal Microscopes can focus on thicker images because they use laser technology, and spinning disk confocal microscopes can actually view live cells. However, high magnification on these types of microscopes often requires either a water or oil immersion lens.

∙ 11y agoAt a high magnification, the image of the organism is 'zoomed in', and it is possible to see the image in great detail. However, this means that you're only looking at a very small part of the organism -- in order to see more, you need to 'zoom out'. It's a trade - off between seeing a small area in great detail, or seeing a large area in less detail.

What is dissecting?
A dissection microscope is called a stereoscopic microscope. It has low magnification that is useful for viewing large, thick objects.
Why would a scientist use a lower power magnification on a microscope?
If he/she was looking at something like a plant cell he would use the smaller lens because they would be much larger then something like a cheek cell which would need the medium or large magnification

What is the term for an organism that has an unusually large effect on the ecosystem?

What are the large and small knobs on the side of a microscope?
The knobs on the side of a microscope are the focus knobs. The large one is the course focus, and the smaller one is the fine focus.
What is Power of magnification?
Example: 2* magnifacaition makes the focused area twice as large as the actual size.

What is the large knob on a microscope?
it is the course focus
What is the maximum magnification of a SEM?
A scanning electron microscope has a very large depth of field which makes the images produced appear three dimensional. Magnifications from 25X to 250,000X (250 times the magnification limit of a light microscope) are possible. Although my Science Text book says it can reach a magnification of 300 000X, but most specimens are easier to view at magnification less than 10 000X.
List of advantages and disadvantages of using low magnification?
Advantages: easy to use, inexpensive (comparatively), can look at live specimens (but its kinda hard to do so), Disadvantages: cannot magnify over 2000 times, poorer resolution (comparatively) ,

How does surface area to volume ratio affects an organism?
If the surface area of the organism is small, then there is no problem with getting all the oxygen needed. If the surface area of the organism is large, therefore a special respiratory surface is needed. An example is lungs, gills. The ratio of surface area to volume in a small organism is greater than the ratio in a large organism.
What is the difference between a body and an organism or are the two words interchangeable?
A body is like a solid, large living object, but an organism can be a tiny cell with no body. Basically, a body is an organism, but an organism is not a body.
What is an example of a large molecule in a living organism?
water (H20)
What is a large organism made up of many millions of?
