This study guide covers key concepts about cells including the cell theory, parts of microscopes, differences between cell types and organisms, cell structures, transport mechanisms like diffusion and osmosis, and levels of organization in multicellular organisms. Students are instructed to learn about early discoveries in cell biology, organelles, differences between plant and animal cells, the cell membrane and cell wall, and cellular processes like endocytosis and exocytosis.
