Parts of animal cells which can be observed using a light microscope

Answer 1

parenchyma, schelanranchya etc

Answer 2

Using a light microscope, one can view cell walls, vacuoles, cytoplasm, chloroplasts, nucleus and cell membrane. Light microscopes use lenses and light to magnify cell parts. However, they usually can achieve a maximum of 2000x magnification which is not sufficient to see many other tiny organelles.
