Chapter 29 An Overview of Land Plant Evolution 1. Describe four shared derived homologies that link charophyceans and land plants. a. The complexes that produce cellulose are rose shaped in both charophyceans and land plants. Next both have peroxisome enzymes that help minimize the loss of organic products from photorespiration. The structure of their flagellated sperm is very similar. Finally‚ both form a phragmoplast during cell division. 2. Distinguish among the kingdoms Plantae‚ Streptophyta
