The type of microscope that we use in our school laboratories is :

1. Simple microscope
2. Electron microscope
3. Compound microscope
4. Both (1) and (2)

Compound microscope

Reason — The type of microscope that we use in our school laboratories these days is the compound microscope. It is used to observe cells, tissues, microorganisms, and prepared slides.
Simple microscope has only one lens and not typically used for detailed observations in school biology labs. Electron microscope requires electricity and special preparation of specimens.
