Cell Organelles Overview: Functions and Structures in Biology

Learn about the functions and structures of essential cell organelles, such as the plasma membrane, mitochondria, and nucleus. Explore the roles of organelles like ribosomes, Golgi apparatus, and lysosomes in maintaining cellular functions. Understand the differences between plant and animal cells as well as prokaryotic and eukaryotic cells.

  1. Cell Organelles Structure and Function of the Cell

  2. Plasma Membrane • The “__________________” • Separates the cell’s ______________ and _______________ environments • Controls what ______________ and ____________ the cell, helps maintain ______________ • Fluid Mosaic Model –__________________ Bilayer

  3. Cell Wall • Found in ______________ • Provides ___________ • Contains ______________-fiber, the cotton in your shirt

  4. Cytoplasm • The stuff or filling of the cell • All the ___________ float in the cytoplasm • Site of many ____________ reactions

  5. Mitochondria • The _________________ of the Cell • Where __________ conversion takes place • Cells that use more energy, have more mitochondria, like muscles

  6. Chloroplasts • Found in plants where _______________ occurs • Where plants produce ________________
