What is the correct order of appearance in the fossil record, starting with the earliest: flowering plants, ferns, gymnosperms?
Step by step
Solved in 2 steps
- During what era and period did the first vascular plants,such as ferns, appear?Draw a phylogeny of the following groups of the Archiplastida: red algae, charophytes, mosses, lycophytes, pterophytes, gymnosperms, angiosperms. Mark on the phylogeny at least six evolutionary transitions in life cycle. Can you please draw on a sheet of paperWhat is the correct order of appearance in the fossil record, starting with the earliest: flowering plants, ferns, gymnosperms?
- What is the evolutionaryimportance of the emergenceof seeds in the plant kingdom?The earliest fossils clearly recognizable as parts of flowering plants are _____________________ __________________ in rocks more than ______________ million years old.According to the cladogram in Figure 27-5, which plants evolved first: nonvascular bryophytes, seedless vascular plants, or seed plants?
- If Rhynia or its contemporaries were the ancestors to the ferns, how did the gametophytes and sporophytes change during evolution?When did plants first emerge? What kinds of fossils were found to give us some ideas about the timeline? What group of green algae is most closely related to plants? How do we know?What key traits distinguish each group from the other listed in the comparison? A) All land plants from green algae? B) Pteridophyta (ferns) from Bryophyta (mosses)? C) Angiosperms from ferns?
- In the vascular bundles of flowering plants, protoxylem is closest to the center of the stem, and metaxylem is farther out. Is this an endarch or an exarch arrangement? Seed plants always have just this one arrangement, but what about the early vascular plants? Were they endarch or exarch, or did both types occur originally?List the signiicant events in the evolution of land plants.using the geologic time scale, what era and period did the first flowering plants appear?
