Expert Answer
Parenchyma cells can be categorised based on their structure, location and functions performed. The main parenchyma tissues are:
  1. Chlorenchyma: Cells which have chloroplast and perform photosynthesis.
  2. Transfer Cells: They play an important role in the transport of solutes over short distances.
  3. Phloem Parenchyma: It stores food and other materials like resins, latex and mucilage.
  4. Xylem Parenchyma: It stores food materials like starch, fats and other substances such as tannins and crystals.
  5. Storage Parenchyma: These store various substances like water, starch, proteins etc. They act as a food and water reservoir.
  6. Prosenchyma: These are fibre-like elongated cells, which are thick-walled and provide rigidity and strength to the plant.
  7. Aerenchyma: They contain very large intercellular spaces. These are present in aquatic plants.
  8. Epidermis Parenchyma: It is found in the epidermis of the leaves of some gymnosperms.
  9. Conjunctive Parenchyma: This type of parenchyma is present in the root system.
