Final answer:
Tissue culture allows rapid propagation of orchids with desired traits for commercial purposes.
Step-by-step explanation:
Tissue culture is used to produce a commercial orchid by allowing rapid propagation of orchids with desired traits. The process starts by sterilizing a part of the plant, such as a stem or leaf, and placing it on a plant tissue culture medium that contains all the necessary nutrients. The plant part forms an undifferentiated mass called a callus, and individual plantlets begin to grow from it. These plantlets are then separated and grown under greenhouse conditions before being transferred to the field for commercial cultivation.
