Features of parenchyma:

• They form basic packing tissue.

• They show large intercellular spaces.
• Cytoplasm is dense with a small nucleus.

• 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.
