What organelles are readily seen under LPO and HPO?

Under low power objective (LPO), organelles such as the nucleus, cytoplasm, and larger structures like vacuoles can be readily observed. When using high power objective (HPO), finer details become visible, allowing for the identification of organelles like mitochondria, endoplasmic reticulum, and Golgi apparatus. However, the visibility of these organelles can vary depending on the type of specimen and staining techniques used.
