What we have learnt
- All living organisms are composed of one or more cells.
- Cells are classified into prokaryotic and eukaryotic based on structural features.
- Plant and animal cells differ in several key aspects, including the presence of a cell wall and chloroplasts in plant cells.
Key Concepts
- -- Cell Theory
- A foundational concept in biology stating that all living organisms are made up of cells, they are the basic unit of life, and all cells arise from pre-existing cells.
- -- Prokaryotic Cells
- Cells that lack a true nucleus and membrane-bound organelles, exemplified by bacteria and blue-green algae.
- -- Eukaryotic Cells
- Cells that contain a true nucleus and various membrane-bound organelles, including plant and animal cells.
- -- Organelles
- Specialized structures within a cell that perform distinct processes necessary for cellular functionality.
