Magnification WKSHT

This document contains a series of microscopy images along with questions to test understanding of cell structure, types of cells, magnification, and organelle identification. Images show a bacteriophage, plant cell structures like leaf veins, animal cells in mitosis, and a prokaryotic cell. Questions assess identifying image details, distinguishing prokaryotic and eukaryotic cells, magnification levels, organelle functions, and differences between plant and animal cells. The goal is to build knowledge of cell biology concepts through analyzing microscope images at varying magnifications.
