#SCPH01 Biochemistry

  1. If a small piece of tissue from a plant stem or leaf is placed on a solid agar medium containing the appropriate nutrients and growth hormones, the cells will start to divide to form a disorganized mass of cells known as a callus.

  2. If a small piece of tissue from a plant stem or leaf is placed on a solid agar medium, it does not need any nutrients and growth hormones, the cells will start to divide to form a disorganized mass of cells known as a callus.
  3. The callus cells are then separated and grown in liquid culture, again containing the appropriate growth hormones

  4. In suspension culture, some of the callus cells divide to form small cell clusters. These cell clusters can resemble the globular stage of a dicotyledon embryo, and with further culture on solid medium, develop through the heart shaped and later stages to regenerate a complete new plant.
