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*

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 ...

Coffin Correct Answer-A case or receptacle for dead human remains which is anthropoid in shape Casket FTC Correct Answer-a rigid container which is designed for the encasement of human remains and which is usually constructed of wood, metal, or like material and ornamented and lined with fabric.

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...

Bryophytes Characteristics Vascular: no Seed Bearing: no Dominant Generation: gametophyte Examples/Phyla: liverwort, mosses, hornwort Special features: use spores, no seeds, need water for reproduction Paleozoic or Mesozoic: Paleozoic Ferns Characteristics Vascular: yes Seed Bearing: no Dominant Generation: sporophyte Examples/Phyla: monilophyta Special features: have sporangium Paleozoic or Mesozoic: Paleozoic Gymnosperms Characteristics Vascular: yes Seed Bearing: yes Dominant...
