Question
Chapter 25.2, Problem 1TYK
Summary Introduction
Introduction:
The process of conversion of plant or animal to fossil is termed as fossilization. It is a very rare process, in which only small number of plants or animals participates. Various biochemical components in plants are converted into fossil as these components are very hard to be decayed by the microorganisms.

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.arrow_forward

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_forward
- Review the life cycles of the three major plant groups (bryophyte or non-vascular plants, seedless vascular plants, and seed plants). Be able to identify the gametophyte and sporophyte generations in each plant group. Make one graph that shows patterns of changes in the following characteristics, as the different plant groups (bryophytes or non-vascular plants, seedless vascular plants, and seed plants) appeared or evolved on land through time. 1) size of the gametophyte generation 2) size of the sporophyte generation 3) biomass (amount of organic material) stored in the sporophyte 4) degree of dependence on water for fertilization Make sure the y- and x- axes of the graph, labels and title are included and correctly applied.arrow_forwardI am studying a plant. The sporophyte is the physically largest phase of this plant’s life cycle. This plant is a _____. Group of answer choices a fern It could be a fern, a pine tree or a rose bush. a rose bush a moss a pine treearrow_forwardWhile exploring a forest, you come upon a plant that you haven't seen before. 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 phylum 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_forward
