Question

What 3 cell organelles are easily seen by a microscope at either 40, 100 or 400X magnification?

Answer 1

Under a microscope at magnifications of 40x, 100x, or 400x, three cell organelles that can be discernible are the nucleus, chloroplasts in plant cells, and mitochondria. Light microscopes typically provide these magnification levels, while electron microscopes offer much higher magnification and resolution for finer details.

Step-by-step explanation:

The question pertains to cellular structures that can be seen under a microscope at magnifications of 40x, 100x, or 400x. Three cell organelles that are easily visible at one or more of these magnifications are:

1. Nucleus: It is the largest organelle within a cell and houses most of the cell's genetic material. Under a light microscope, the nucleus is conspicuous and can be identified at lower magnifications, such as 100x.
2. Chloroplasts (in plant cells): These are involved in photosynthesis and are relatively large, easily spotted by their green color due to the presence of chlorophyll under a magnification of 400x.
3. Mitochondria: Known as the powerhouses of the cell, mitochondria can be seen under higher magnification settings such as 400x, due to their size and distinctive structure.

It is important to mention that while light microscopes in a college biology lab can magnify up to approximately 400 times, electron microscopes provide much higher magnification and resolution, allowing for detailed study of cellular structures.
