SCIENCE REVIEW ON CELLS Organelles By Function Plant-Specific Features Chloroplast Control: Nucleus -where photosynthesis occurs. It contains chlorophyll that captures light energy. -Only plant cells have chloroplasts. Manufacturing: Ribosomes, Smooth Endoplasmic Reticulum Cell Wall -A plant cell is surrounded by a protective outer covering called a cell wall. -The rigidity of the cell wall permits plant cells to maintain their shape. Energy Processing: Mitochondria, Chloroplast Storage/Transport: Golgi, CELL THEORY Vesicles CELLS 1. Cell Theory Robert Hooke: Discovered cells in cork Matthias Schleiden: Plants made of cells Cell Structures Cell Types Theodor Schwann: Animals made of cells Prokaryotic Cells Rudolf Virchow: Cells come Cell Membrane No membrane-bound nucleus from existing cells -protective skin Has cell wall and pilus Cytoplasm Free-floating genetic material -jelly like substance Eukaryotic Cells Cytoskeleton Has membrane-bound nucleus -tiny threads that give structure Contains organelles DNA within nucleus
