Concept 5: Ground Tissues

The three types of ground tissue, parenchyma, collenchyma, and sclerenchyma, function in photosynthesis, storage, regeneration, support, and protection.

Use information from the table to help answer the questions below it.

Ground Tissue Function Cell Types in This Tissue
Parenchyma Tissue
  • Photosynthesis
  • Food storage
  • Healing and tissue regeneration
Parenchyma cells
Collenchyma Tissue
  • Support in young stems, roots, and petioles
Collenchyma cells
Sclerenchyma Tissue *
  • Rigid support
  • Protection
Sclereid cells & fiber cells
* Some texts include tracheids and vessels as components of sclerenchyma tissue.
