1. Definition of Cell
- Basic structural and functional unit of all living organisms.
- All organisms are made of cells; cells arise from pre-existing cells.
- True nucleus present with nucleolus.
- Ribosomes are 80S (larger).

- Cell wall (in plants) is made of cellulose.
- Cross-section of a leaf (showing tissues)
- Animal cell vs. Plant cell
- Mitosis stages (any one stage – usually Metaphase)
- Single membrane sacs containing hydrolytic enzymes.
- "Suicidal Bag" – dig worn-out organelles or the cell itself during stress.
The second chapter of SSC biology is titled "Structure of Living Organisms."
