Steps in Tissue Culture
- Selection and preparation of explant
- Sterilization
- Media preparation (Murashige and Skoog medium)
- Inoculation
- Incubation and maintenance
- Subculturing
- Rooting and acclimatization
Applications of Tissue Culture
- Micropropagation (clonal propagation)
- Production of haploids and dihaploids
- Genetic modification and production of transgenic plants
- Somatic hybridization
- Conservation of endangered species
- Production of secondary metabolites
Advantages and Disadvantages of Tissue Culture
- Advantages (rapid multiplication, disease-free plants, etc.)
- Disadvantages (cost, technical expertise required, etc.)

These topics cover the essential aspects of plant families and tissue culture, crucial for understanding plant classification, propagation, and biotechnology applications, and preparing for NEET Biology.
