Submicroscopic, optical microscope, and microscope can see what the cell structure is
Microstructure refers to the structure that can be observed under an optical microscope.
For cells: cell walls, nuclei, endoplasmic reticulum, mitochondria, chloroplasts, Golgi bodies, etc. can be directly observed under an optical microscope and belong to the microstructure;
Note that only the shape of organelles can be seen, and the internal detailed structure is invisible. For example, chloroplasts can only be seen as green oval particles, and the grana inside is a submicroscopic structure.
Submicroscopic structure refers to the structure that can be observed under the electron microscope.
For cells: cell membranes, ribosomes, various membrane structures, and the internal detailed structures of various organelles are submicroscopic structures.
Therefore, chromosomes can be seen with a high magnification lens (belonging to optical microscope, microstructure).
Chromatin cannot be seen but can be seen under an electron microscope.
Chromatin is highly helical into chromosomes, and chromosomes can be observed under high-power microscope after staining with basic dyes.
