This book focuses on plants evolutionary impact on the rest of the Earth. It begins by focusing on the importance of leaves to plants, as well as the presence of genes in earlier plants, without the genes necessarily being activated. It moves to a basic overview of greenhouse gases before continuing onto oxygen’s history on earth and its effects on almost all organisms. The book also comments on plants’ interaction with oxygen and the cycling of oxygen. The next couple of chapters focus especially on plants’ effect on the atmosphere. They also consider plant fossil’s ability to show evidence of different atmospheric variants, such as ultraviolet radiation and carbon dioxide levels. Then the book goes on to explain how plant fossils can also show how very different the plant was millions of years ago, by the anatomy and physiology of the plants as well as the location of the fossils. It then continues on how plants with different strengths interact with each other and end up affecting the Earth’s biosphere and atmosphere. An example is gymnosperms which use wind pollination and can colonize recently devastated ecosystems, and angiosperms with flowers and fruits, which focus on insect and animal pollination, meaning they do better in established ecosystems. …show more content…
Plants have persisted through many mass extinction events, and even today continue to cover most of the planet. It also points out ferns being some of the first organisms to re-inhabit a habitat recently wiped of life, whether by volcanoes or fire. The book further explains why there is so much variation in plants, the benefits and downfalls, of these, and the correlating effects. The author additionally puts a strong emphasis on the people and scientists who effected palaeobotany research and many research assumptions and discoveries. While plants have changed our planet greatly, by studying them, we can also solve some of science’s other
Fossils Tell of Long Ago uses accessible language and illustrations to aid all students in vocabulary and new concept growth. Explicit instructions, reading the book allowed to the class, and allowing conversation among individual students as they work through learning new words will aid ELL students in expanding their word knowledge. Furthermore, having ELL students translate new word to into their native language will help them activate their previous knowledge. Encouraging all students to be actively engage in learning words will ensure that ELL students and all students will gain knowledge and make connections to new words.
From a diagram of an idealized flower, correctly label the following structures and describe the function of each structure:
Plants are found everywhere on earth, up high on the ridge and down low in caves and caverns. The types of plants that live in these places depends on many factors. These factors are separated into two different categories, the biotic factors and the abiotic factors. Some of the biotic factors include, predation, competition, and habitat destruction. Plants with limited competition and large amounts of resources will be in a higher abundance than plants with limited resources and higher competition rates will be confined to areas and either out competed or will be the dominant species. Certain plants adapt to these factors and thrive and others don’t do as well. Some of the abiotic factors include, sunlight, water, temperature, and wind. These
Ruby Hamad’s article, published on the 27th of October, 2014 was discussing the three men from the group “Faceless”, who walked into parliament house on the 26th of October, 2014 wearing a motorcycle helmet, a Niqab and a Klu Klux clan outfit. Their argument was that allowing women into parliament wearing a niqab or burka was sexist and a privilege towards these women.
The skeletal characteristics of these hominines suggest that their mode of locomotion was likely a cross between occasional bipedalism and obligate bipedalism. From the reading we have learned that obligate bipedalism is bipedal locomotion that is practiced all of the time while occasional bipedalism is bipedalism that is practiced on occasion. The ratio of arm length to leg length (longer arms) suggests that they did spend time climbing trees, however the cranial and post cranial traits of these fossils suggest that they spent much of their time on the ground and likely ambulating bipedally combined with a variation of upright walking and knuckle walking. This is evidenced by two factors: the fact the foramen magnum of the skull is centrally located, and the ratio of arm to leg length. In creatures with bipedal ambulation, the foramen magnum is located in the center of the base of the skull to keep the head aligned over the center of gravity of the creature. If the fossils were walking primarily with their knuckles, the
First, the reading passage poists that the Yellowstone fire caused termendus damage to the park's trees and other vegitation. The professor contradicts this notion by stating that the scorched area was a suitable place for emergence of new plants which were unable to grow before the Yellowstone fire. Thus, according to the professors claims, this area will have more diversy vegitation than before the Yellowstone fire.
Second, the reading states that park wildlife was affected as well. In contrast, the professor in the lecture averts that the small plants that grow create ideal
Introduction: Fossils are defined as a physical trace or evidence of life from a prior geological time period which has been preserved. Examples of fossils include burrows, indentations or bite marks, footprints or other impressions, coprolites, hard animal body parts such as bone, shells or horns or mineralized plant remains embedded in stratified rock.
Plant life appeared almost 2 billion years ago. There has been estimated that over 5 billion species have formed and have become extinct. Only 14% of our current species have been documented and described. Even today geological change has been happening and our species hasn’t stopped evolving. But that is getting ahead of
Throughout history, land employed for agricultural production has caused greater environmental change to the biosphere than any other land use (Gliessman, 2010).

The warming of earth proved to be a great advantage for the mass expansion of plants and a coinciding gain for humans as well, since a vast amount of plants were beginning to exist closer to humans according to Elizabeth Pollard et al. in Worlds Together, Worlds Apart (22). During this era, humans gained control over the reproduction of
Marijuana is a very controversial issue in society today. There have been many false claims about cannabis, but the truths are starting to resurface. Marijuana has many good purposes other than creating the feeling of a “high” and i think that is what people need to understand. You will many times hear the stereotypical view of what people see as a “pot smoker” who is lazy and unmotivated and while that may seem true, it isn’t entirely correct. If someone is lazy and unmotivated before using weed, they will remain the same after. Though there are many cons about marijuana, they aren’t entirely true and marijuana has many benefits that will help everyone. I strongly believe that marijuana should be used for all uses.
In addition, biodiversity will be crucial for humanities continued survival in the case of climate change or widespread crop failures. The majority of people on earth are reliant on four crops for subsistence; wheat, rice, corn, and millet. (11) These crops are threatened by climate change and the spread of disease facilitated by modern transportation. If humanity is to survive such an eventuality it must be ready to draw upon the earth’s biodiversity for replacements. And while there are approximately 50 thousand plant species that could offer alternatives, this bank of resources is quickly thinning as various ecosystems are being destroyed. (11)
When the author reflects on meanings of the finds we again observe the fact that although initially there was relatable and similar fraction in the early onset of the post-fire succession inevitably over time a gradual decrease in fraction was observed. The author also notes that native-exotic correlations not only vary across communities and spatial scales but as he finds through time as well. The author revealed that in the infantile stages of the post-fire chaparral succession exotics such as short lived herbs tended to emerge first followed by native and exotic perennials, and then ultimately the dominant native species such as the previously mentioned shrubs. Guo also noted that this study yielded the findings that in the California chaparral community in which he conducted his experiment,
