PPT-Cells organelles

Before we begin what are organelles Cells organelles If we have organs cells have Organelles Specialized parts of the cell with specific functions Cells organelles. Both are chemically similar in that they contain nucleic acids, proteins, lipids, and carbohydrates. They use the same sort of chemical reactions to . metabolise. food, build proteins and store energy. Cell theory. Cell organization and homeostasis. Studying cells – microscopy and fractionation. Eukaryotic vs. prokaryotic cells. Compartments in eukaryotic cells (cell regions, organelles). Cytoskeleton. Organelles do the work of cells. each structure has a job to do. keeps the cell alive; keeps you alive. Model Animal Cell. 1. Cells need power. !.
