1 UNIT 3 CP BIOLOGY: Cell Structure Page CP: CHAPTER 3, Sections 1-3; HN: CHAPTER 7, Sections 1-2 Standard B-2: The student will demonstrate an understanding of the structure and function of cells and their organelles. Indicators: B-2.1 B-2.2 B-2.3 Recall the three major tenets of cell theory (all living things are composed of one or more cells; cells are the basic units of structure and function in living things; and all presently existing cells arose from previously existing cells). Summarize the structures and functions of organelles found in a eukaryotic cell (including the nucleus, mitochondria, chloroplasts, lysosomes, vacuoles, ribosomes, endoplasmic reticulum [ER], golgi apparatus, cilia, flagella, cell membrane, nuclear membrane, cell wall, and cytoplasm). Compare the structures and organelles of prokaryotic and eukaryotic cells. Vocabulary: Cell Theory Nucleus Prokaryotic Cell Endoplasmic Reticulum Eukaryotic Cell Organelle Cytoskeleton Cytoplasm Ribosome Golgi Apparatus Vesicle Vacuole Mitochondrion Lysosome Cell Membrane Cell Wall Chloroplast Centriole Nucleolus Peroxisome Define the following Vocabulary Terms: Cell Theory: Prokaryotic Cell: Eukaryotic Cell: Organelle:
