Seed Evolution Steps - ANSWER Homospory Heterospory Megasporangium Surrounded by Sterile Telomes Free Tips Phylum Cycadophyta - ANSWER Earliest Gymnosperms Mesozoic Era (65-230 MYA) 11-12 Genera Mostly tropical and subtropical Resemble palms - unlike palms they have a vascular cambium (stem can increase in width) Often highly toxic to dogs, cats, and livestock Reproductive structures associated with modified leaves - microsporophylls and megasporophylls Loosely or tightly clustered ...

Part A All seed plants _____. - are heterosporous Correct: All seed plants produce separate male and female spores. Part A An ancient date palm seed germinated and grew into a healthy plant. What was the source of nutrients for the young sporophyte embryo during germination of the date palm seed? - food stored within the seed Correct: A seed consists of an embryo and a food supply, packaged in a protective seed coat derived from the integument(s). Part A Angiosperms are different from ...

What is the ecological importance (historically and presently) of seedless vascular plants? - Answer - Vascular tissue and lignin enable plants to grow tall and inhabit drier habitats - Increased terrestrial plant abundance and diversity (habitat and food resources) enables increased biodiversity and organism abundance Where do gymnosperms inhabit? - Answer Terrestrial ecosystem What are the characteristics of gymnosperms? - Answer - Cuticle and stomata* - Vascular tissue and lignin*

Question 1. Based on figure 4.1, is it correct to state that we understand deep relationships among Eukaryotes? How do we represent ambiguity in branching pattern on phylogenetic trees? Hint: look at figure 1.27. No, we cannot say we understand deep relationships among Eukaryotes because there is a polytomy that represents ambiguity on the phylogenetic tree. No, you cannot define deep relationships amongst eukaryotes because the nodes include polytomies which signifies ambiguity/indefinite...
