You have access to the sequence genomes for moss and the lycophyte Selaginella. Your goal in analyzing the data is to write a ground-breaking paper that answers an important question about the evolution of plants. What questions would you try?
Plants made the leap from water to land during the late Ordovician period (we think). In order to make it, various physical obstacles had to be overcome.
Choose one adaptation and explore it further. What evidence do we have of this change? Are there specific fossils of plants that exhibit it? How do we think it may have developed? Not all of these changes occurred at the exact same time. Was your chosen adaptation one of the first or late to the game?
including references are appreciated.
You are asked to survey an area and identify all plant and animal species you come across. On your
survey, you come across a plant you are not familiar with and must do some research to figure out what it
is. To do this, your first step is to determine whether this plant is classified in the class Monocotyledonae
or a Eudicotyledonae. Explain how you can tell if this plant is a Monocot or Eudicot by describing the
differences in their flowers, seeds, roots, stems, and leaves.

- working in the field, you discover a fossil of a previously undescribed plant species. the specimen is small and may not be complete; the parts you have do not include any floral organs. what sort of observations(evidence) would you need in order to classify the fossil as a vascular plant with reasonable accuracy? what evidence would you need to distinguish between an angiosperm and a gymnosperm?arrow_forwardPut the following 3 fictional plants in order from earliest to most recent according to their characteristics: A. The Terpad Plant: This plant reproduces using spores and has proper leaves and vascular tissue. B. The Feltris Plant: The Feltris plant lives in moist environments since it doesn't have any vascular tissue to maintain hydration throughout the plant. This plant has no roots either but has small root-like structures called rhizoids which help anchor them to the ground. Water is also required in order for fertilization. C. The Lancelot Plant: This plant can grow in either moist or dry environments, has true roots, stems and leaves and reproduces via seeds which develop within an ovary.arrow_forwardDiscuss and explain the origin of plants to green algae.arrow_forward

You dig it up and take it back to your lab for further inspection. Back at the lab, you observe the characteristic structure of the plant and make some notes. Then, you carefully dissect the stems and leaves and look at the tissue under the microscope. Finally, you are able to determine the type of plant it is. Use the notes below to identify the class to which this plant belongs. Notes on physical characteristics of the specimen: the plant has no leaves or roots, but has hair-like rhizomes which anchors it in the soil the stems are highly branched sporangia are present at the ends of each stem dissection of the stem shows the presence of vascular tissue in the form of a xylem and phloemarrow_forwardThe Apiaceae is closely related to the Araliaceae, the family to which ginseng and octopus tree belong.
