Key Concepts
- Scientific investigation follows: Observation โ Hypothesis โ Experiment โ Analysis โ Conclusion
- A model is a simplified representation of reality โ not an exact copy
- Variables: Independent (you change), Dependent (you measure), Controlled (stays same)
- A scientific theory is strongly supported by evidence โ not just a guess
Important Terms
- Hypothesis: Testable prediction made before an experiment
- Variable: Any factor that can change in an experiment
- Control group: Receives no treatment; used as a baseline for comparison
- Data: Recorded observations or measurements
Process Flow
QuestionโบHypothesisโบExperimentโบObserveโบAnalyseโบConclude
Common Mistakes
- Writing the conclusion before the experiment โ science follows evidence
- Changing multiple variables at once โ only one should change at a time
- Treating a hypothesis as a proven fact before testing it
Quick Revision
- Scientific knowledge changes as new evidence emerges
- Repeating an experiment increases reliability
- Qualitative data = descriptive; Quantitative data = numerical
- A control group shows what happens without the experimental treatment

Key Concepts
- Cell = basic structural and functional unit of all living organisms
- Cell Theory: All organisms are made of cells; cells arise from pre-existing cells
- Prokaryotes (bacteria) = no membrane-bound nucleus; Eukaryotes = have a nucleus
- Cell membrane is present in ALL cells; cell wall only in plant/fungal cells
Important Terms
- Cell membrane: Thin flexible layer โ controls entry and exit (selectively permeable)
- Nucleus: Contains DNA; directs all cell activities (absent in prokaryotes)
- Mitochondria: Site of cellular respiration โ produces ATP energy
- Chloroplast: Site of photosynthesis โ contains chlorophyll (plant cells only)
Process Flow
SunlightโบChloroplastโบPhotosynthesisโบGlucose + Oโ
Common Mistakes
- Confusing cell membrane (flexible, all cells) with cell wall (rigid, plants only)
- Thinking all cells look alike โ they are highly specialised
- Placing the nucleus outside the cell membrane in diagrams
Quick Revision
- Animal cells = no cell wall, no chloroplasts, have centrioles
- Plant cells = have cell wall, chloroplasts, large central vacuole
- Mitochondria have their own DNA โ evidence of endosymbiotic origin
- Robert Hooke first observed cells in cork in 1665

Key Concepts
- Tissues = groups of similar cells working together for a specific function
- Animal tissue types: Epithelial, Connective, Muscular, Nervous
- Plant tissue types: Meristematic (dividing) and Permanent (non-dividing)
- Hierarchy: Cell โ Tissue โ Organ โ Organ System โ Organism
Important Terms
- Epithelial tissue: Covers surfaces and lines organs โ protective
- Meristematic tissue: Actively dividing cells found at growing points
- Xylem: Dead tissue โ transports water and minerals upward
- Phloem: Living tissue โ transports food (sugar) in both directions
Process Flow
CellโบTissueโบOrganโบOrgan SystemโบOrganism
Common Mistakes
- Confusing organ with tissue โ tissue = one cell type; organ = multiple tissues
- Thinking xylem is living โ it is made of dead cells that form hollow tubes
- Placing meristematic tissue only at root tips โ also at shoot tips
Quick Revision
- Striated muscle = voluntary control; Smooth muscle = involuntary
- Xylem = dead cells; Phloem = living cells
- Sclerenchyma gives mechanical strength to plants โ also dead cells
- Nervous tissue has the longest cells in the body โ nerve cells (neurons)
