Does any one have the comparison between the sizes of cell organelles and also what kind of structures can be observed under each of the light and electron microscope?

Cell (per side)

50 um

Nucleus (diameter)

7 um

Cell membrane

7 nm thick

Endoplasmic reticulum

.2 um, each layer (.1 um between)

Golgi complex

7 nm thick, each layer


30 nm in diameter


2.5 um in diameter

Cell wall

2 um thick


1 x 3 um

Lysosomes (diameter)

1 um

Vacuoles (diameter)

3 um

Organelles which can be seen under light microscope are nucleus, cytoplasm, cell membrane, chloroplasts and cell wall. Organelles which can be seen under electron microscope (highest magnification to more than 200,000x) are ribosomes, endoplasmic reticulum, lysosomes, centrioles, and Golgi bodies.

I think you can see the golgi body and the centriole in a very high quality light microscope as well

Is it really necessary to know the sizes of each organelle?
I haven’t seen a question about it
Maybe i missed?!:woman_shrugging:t2:

Thank you Armita.
I just wanted to know it in more detail… that’s why I asked here.

@Armita obviously not. You don’t need to know the exact sizes. I just wanted to study further:/
