Tissue is the next level after the cell. Your hand note should classify tissues like this:
| Feature | Prokaryotic | Eukaryotic | | :--- | :--- | :--- | | Nucleus | No true nucleus (Nucleoid) | True nucleus with membrane | | Organelles | Only ribosomes | All organelles (Mitochondria, ER, etc.) | | Size | 1-10 µm | 10-100 µm | | Example | Bacteria, Cyanobacteria | Plants, Animals, Fungi | ssc biology chapter 2 hand note exclusive
| Fact | Memory Trick | | :--- | :--- | | Plant tissues: Meristematic + Permanent | “MP” (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” | Tissue is the next level after the cell
