| Organelle | Found in | Function | | :--- | :--- | :--- | | | Both | Controls all cell activities; contains DNA & Chromosomes. | | Mitochondria | Both | Powerhouse of cell; produces ATP energy. | | Ribosome | Both | Protein synthesis. | | ER (Endoplasmic Reticulum) | Both | Transport of materials. (Rough ER = protein; Smooth ER = lipid) | | Golgi Body | Both | Packaging & secretion of cell products. | | Lysosome | Animal | Suicidal bag ; digests waste & germs. | | Chloroplast | Plant | Photosynthesis (contains green pigment Chlorophyll ). | | Cell Membrane | Both | Semi-permeable; controls entry/exit of substances. |
: Cells with a true nucleus and membrane-bound organelles (e.g., plant and animal cells). 2. Key Cell Organelles & Functions : Known as the ssc biology chapter 2 hand note exclusive
This report synthesizes the core concepts found in the "SSC Biology Chapter 2: Cells and Tissues of Organisms" exclusive hand notes. The chapter serves as a foundational pillar for secondary biology, focusing on the microscopic structure and functional organization of living beings 1. Cellular Foundations | Organelle | Found in | Function |
: Found throughout the cytoplasm, they digest and break down old organelles. | | ER (Endoplasmic Reticulum) | Both |
| Fact | Memory Trick | | :--- | :--- | | Plant tissues: Meristematic + Permanent | (Meristem = growth; Permanent = fixed work) | | Animal tissues: Epithelial, Connective, Muscular, Nervous | “ECMN” (Every Cell Makes Nerve) | | Mitochondria function | “ATP factory” | | Lysosome function | “Police + Cleaner” of cell | | Cell wall composition | “Cellulose = Cement of plant cell” |
