what are the characteristics of Parenchyma, Collenchyma, and Sclernchyma?
Features of parenchyma:
- They form basic packing tissue.
- Cells of this tissue are relatively unspecialised and may be oval, rounded or elongated in shape.
- Their cell walls are thin.
- These cells are living.
- They show large intercellular spaces.
- Cytoplasm is dense with a small nucleus.
- The celss possess a large central vacuole.
- Parenchyma provides support to plants and also stores food
Features of Sclerenchyma:
- Their cells are dead.
- Cells are long and narrow.
- Cells are empty and devoid of protoplasm.
- Cell walls are highly thickened due to lignin deposition.
- There is no internal space inside the cell.
- Cells are closely packed, with no intercellular spaces.
- It is a strengthening or mechanical tissue.
Features of collenchyma:
- They possess living cells.
- It shows deposition of extra cellulose at the corners of the cells.
- Intercellular spaces are generally absenjt.
- Their cells are elongated in shape.
