== <span style="color: #FFFFFF;">Remembering</span> == * '''Morphogenesis''' β The biological process that causes an organism to develop its shape. * '''Pattern Formation''' β The process by which embryonic cells "Form ordered structures" in space. * '''Morphogen''' β A signaling molecule that flows through an embryo to tell cells "Where they are" and "What to build" based on its concentration. * '''Apoptosis''' β "Programmed Cell Death" used to "Shape" the body (e.g., removing the tissue between fingers to make "Hands"). * '''Cell Migration''' β The movement of cells from one part of the embryo to another (the "Travel" phase of development). * '''Cell Adhesion''' β The "Stickiness" of cells; how they "Recognize" and "Cling" to their neighbors to form "Sheets" or "Organs." * '''Cadherins''' β The "Molecular Glue" proteins that help cells stick together. * '''Polarity''' β The "Directional Sense" of a cell (which way is "Up," "Down," "Front," or "Back"). * '''Epithelial-Mesenchymal Transition (EMT)''' β A process where "Fixed" cells (Epithelial) become "Mobile" (Mesenchymal), allowing them to "Crawl" to new locations. * '''The 'Hox' Genes''' β The "Master Switches" that define the "Body Plan" and ensure your "Legs" don't grow where your "Arms" should be. </div> <div style="background-color: #006400; color: #FFFFFF; padding: 20px; border-radius: 8px; margin-bottom: 15px;">
