What to Focus On
- Totipotency means a single cell can form a whole plant.
- Term coined by Morgan in 1901.
- Basis of plant tissue culture technology.
- Six steps: medium preparation, sterilization, explant preparation, inoculation, incubation, acclimatization.
- All steps require aseptic conditions.
- Success depends on proper nutrient supply and growth regulators.
- Contains macro and micronutrients, vitamins, sugars, and amino acids.
- pH maintained between 5.6 and 6.0.
- Agar used as solidifying agent.
Common Mistakes to Avoid
Any plant part can be used as an explant without sterilization because plants are naturally clean.
Totipotency means any cell can grow into a plant without any special conditions or nutrients.
The nutrient medium only needs soil and water to work like in natural conditions.
