Episode notes
Cells: Basic Life Units
- Cells are the smallest units capable of life and comprise all living organisms.
- They perform essential functions like transport, energy acquisition, waste disposal, replication, and environment response.
Why Cells Stay Small
- Cells remain small due to volume increasing faster than surface area, limiting nutrient intake.
- They adapt by having membrane folds to enhance surface area for nutrient exchange.
Prokaryotic vs Eukaryotic Cells
- Prokaryotic cells lack a nucleus and organelles, are smaller, and include bacteria.
- Eukaryotic cells have nuclei, many organelles, are larger, and evolved later, forming complex life.
