Biology EOC Review: Cells Insights

Miss Hamill discusses cell structure, function, and transport. The video covers cell theory, types of cells, and the endosymbiotic theory. It explains the differences between prokaryotic and eukaryotic cells, and details the functions of various organelles. The video also explores cellular movement, including passive and active transport, and the role of the cell membrane.
