Cell Structure & Organelles Difference B/T Plant & Animal Cells

Cell Organization (Eukaryote cells) • Cytoplasm: portion of cell outside the Nucleus • Organelles: structures in cell, act like specialized organs • Nucleus: contains cells DNA

Cellular Boundaries Regulates what enters & leaves a Cell, also protect & support Cell Membranes: lipid bi-layer (2 lipids) selectively permeable (some things pass, some don’t)

Cell Walls (not animal) Just outside cell wall Give support, shape & protect cell Allow water, carbon dioxide (in) & oxygen (out) Give plants strength to stand

Organelles that Capture & Release Energy • Chloroplast: only plants like solar power plants capture energy from SUN & convert into chemical energy stored in food during photosynthesis • Mitochondria: All CELLS Power plant of cell Converts chemical energy stored in food molecules into compounds that are easier for the cell to use The folds give the mitochondria more surface area to aide in energy conversion

Organelles that Build Proteins • Ribosomes: Proteins are assembled on Ribosomes • Endoplasmic Reticulum: (rough & smooth) Proteins enter the rough ER from the Ribosomes, where they are chemically modified • Golgi Apparatus: Modifies, sorts & packages proteins

Organelles that store, clean up & support • Vacuoles: Store salt, water, proteins & carbohydrates Plants: LARGE CENTRAL VACUOLE: rigid, store liquid Animal: much smaller • Lysosomes: only in animal cells Filled with enzymes Break down Lipids, Carbohydrates & proteins that can be used by rest of the cell • Cytoskeleton: Helps cells maintain their shape Involved in movement
