Episode notes
How Colors Mix
- Color perception is due to light reflecting off objects.
- Mixing blue and yellow paints creates green because they absorb all other colors.
Blood in Humans vs. Insects
- Human blood is a closed, pressurized circulatory system delivering oxygen and nutrients.
- Insects have an open system with hemolymph, explaining why squished cockroaches appear to bleed yellow or black.

- Plants grow from their tips, with meristematic cells differentiating into various plant parts.
- The hormone auxin controls branching, and the golden ratio optimizes leaf and branch placement for sunlight.
