Sclerenchyma
- Sclerenchyma cells have thick, lignified secondary cell walls.
- These walls are rigid and provide structural support to the plant.
- The cell walls contain a high amount of cellulose, hemicellulose, and lignin.
- Sclerenchyma cells are dead at maturity and have no living protoplasts.
Collenchyma
- Collenchyma cells have unevenly thickened primary cell walls.
- The walls are flexible and provide support to growing plant parts.
- The walls are composed of cellulose, hemicellulose, and pectin.
- Collenchyma cells are living at maturity and have a thin layer of cytoplasm lining the cell wall.
Parenchyma
- Parenchyma cells have thin, primary cell walls.
- These walls are flexible and allow for various cellular functions such as photosynthesis and storage.
- The walls are primarily composed of cellulose, pectin, and hemicellulose.
- Parenchyma cells are living at maturity and contain a large central vacuole for storage.
