Selectively permeable – Fluid Mosaic Model. 📌 Cell Wall (Plant only): Made of Cellulose – provides rigidity. 📌 Nucleus: Contains DNA + Nucleolus (makes ribosomes). 📌 Mitochondria: "Powerhouse" – produces ATP (Energy). 📌 Ribosomes: Protein synthesis. 📌 Endoplasmic Reticulum (ER): Rough (has ribosomes) → Protein transport; Smooth (no ribosomes) → Lipid synthesis. 📌 Golgi Body: Packaging & secretion. 📌 Lysosomes: "Suicidal bags" – contains digestive enzymes. 📌 Plastids (Plant only): Chloroplast (photosynthesis), Chromoplast (color), Leucoplast (storage). 📌 Vacuole: Storage (large in plants, small in animals). ssc biology chapter 2 hand note exclusive
