1/28/2009 1 Plant Structure Goals of the lab: to observe the major cell types in plants to observe important 1 o and 2 o tissues in plants to distinguish between monocots and dicots to observe tissue arrangement in stems and roots Common Plant Cell Types Parenchyma cells Collenchyma cells Parenchyma cells are “generic”, relatively undifferentiated plant cells. Collenchyma cells cells have unevenly thickened cell walls; they are often found in tissues that lend structural support to the plant. Common Plant Cell Types There are 2 types of sclerenchyma cells: fibers and sclereids . Both have very thick cells walls, often embedded with a strengthening compound called lignin . Fibers are long cells, and usually dead at maturity. Sclereids are short & broad; their heavy, thick cell walls provide protection against herbivores. Common Plant Cell Types Vessel members and tracheids are dead at maturity. They function as “pipes” in roots to transport water and dissolved
