Dominique Key Chapter 29 Outline Morphological and Molecular Evidence: Rosette-shaped cellulose-synthesizing complexes. The cells of both land plants and charophytes have circular, petal-shaped arrays of proteins in the plasma membrane. These protein arrays synthesize the cellulose microfibrils of the cell wall. In contrast, noncharophyte algae have linear arrays of proteins that synthesize cellulose. Peroxisome enzymes. The peroxisomes of both land plants and charophytes contain enzymes that help minimize the loss of organic products as a result of photorespiration, the peroxisomes of other algae lack these enzymes. Structure of flagellated sperm. In species of land plants that have flagellated sperm, the structure of the sperm closely resembles that of charophyte sperm. Formation of a phragmoplast. Particular details of cell division occur only in land plants and certain charophytes including the genera Chara and Coleochaete. For example, in these
