What to Focus On
- Cell is the structural and functional unit of all living organisms.
- Robert Hooke first observed cells in 1665 using a cork slice.
- Prokaryotic cells lack a membrane-bound nucleus (e.g., Bacteria).
- Cell wall is present only in plant cells, fungi, and bacteria — NOT in animal cells.
- It is non-living and freely permeable.
- Made of cellulose in plants, chitin in fungi, and peptidoglycan in bacteria.
- Cell membrane is present in ALL cells — both plant and animal.
- It is living and selectively permeable.
- Made of phospholipid bilayer with embedded proteins — described by Fluid Mosaic Model.
Common Mistakes to Avoid
Cell wall and cell membrane are the same thing — both are the outer boundary of a cell.
Lysosomes are present in both plant and animal cells.
Mitochondria only produce energy (ATP) and have no other role.
Memory Tips
Cell is the basic structural and functional unit of life
Cell Wall — freely permeable, non-living, made of cellulose, only in plant cells
Cell Membrane — selectively permeable, living, made of lipid and protein
Nucleus — controls all cell activities, called the brain of the cell
