3) Leaves are photosynthetic organs found on the sporophytes of most extant vascular plants. Based on a combination of molecular data and fossil evidence, it appears that leaves have evolved more than once. Using the information in Figure 29.13 (p. 629 of your textbook), explain leaf evolution in the vascular plants by answering the following questions. a. Lycophyta are a clade of vascular plants that have leaves called microphylls. Do microphylls represent a synapomorphy or a homoplasy in the Lycophyta?...

Below is a phylogenetic tree of a few major groups of photosynthetic organisms. At each node on the tree (branching point) we can list specific features, indicated by numbers, that are characteristic of the organisms higher on the tree. Using only the features provided in the list below, denoted by letters, place each feature in its appropriate spot on the tree. Each feature should be used only once. - Chlorophytes - Charophytes - Bryophytes - Club Mosses - Horsetails Terrestrial...

In vascular plants: a) the xylem transports solutes throughout the plant, while the phloem is responsible for water transport. b) vascular tissue is only found in the flowers. c) water loss by evaporation is reduced by the waxy cuticle and apical meristems. d) water is drawn up from soil to the leaves in a process called transpiration.
