a) Parenchyma - Loosely packed
b) Lumen - Collenchyma
c) Elongated cells - Sclerenchyma
• Note: Both Sclerenchyma and Collenchyma contain lignin but it is wide in Collenchyma whereas it is narrow in Sclerenchyma. In schlerenchyma, there are two main cells - fibers and sclereids. Fibers are elongated cells which are found in stem, roots and vascular bundles of leaves.
