In an ideal world, plants would not be cut down; in an ideal world, animals would be allowed to survive; in an ideal world, humans would value the life that grew around them. Sadly, this is not our world. Every year, nearly 900,000,000 trees are cut down. In this decade alone, our percentage of deforestation has increased by 8.5 percent. How can humans allow this to go on? Why do they not see the true value of plants? Why can they not appreciate the beautiful mechanics of these fine specimen? Plant lives matter. Like humans, they have cells that make up their foundation. Like humans, they are made up of several organelles. Like humans, they are alive. In chapter 7, section 3 of Biology, the Dynamics of Life, they teach students about the organelles …show more content…
While there is a nice structure to the plant cell, it's the numerous functions that are carried out daily, that are truly impressive. For instance, within the cytoplasm, the cytoskeleton lurks. Like the skeletal system in the human body, the cytoskeleton provides structure to the cell. Also, it helps maintain a stable internal structure. Peroxisomes, which are also located in the cytoplasm, aid in destroying toxins that enter the cell. When the cytoplasm works in tandem with the cytoskeleton and the peroxisomes, the cell is more stable. Furthermore, in a plant cell, there is a series of highly folded membranes known as the endoplasmic reticulum (ER). The ER is divided into two sections. There is the smooth endoplasmic reticulum (SER) and a rough endoplasmic reticulum (RER). While the RER has ribosomes on its surface, the SER is bare. Furthermore, the RER houses protein synthesis, while the SER plays an important role in the cells metabolism. Working with the ER, the Golgi Apparatus, an organelle, takes the proteins from the RER and modifies/distributes them. Also, like any life form, a plant cell stores food and waste. Inside of the cell is an organelle called a vacuole. A vacuole is a sac that is used for storage. While they are usually small in animal cells, vacuoles are very big in plant cells. This is due to a need for long-term storage. Finally, for the plant cell to use all its organelles, it needs energy! The powerhouse of the cell, the mitochondria, is a star! By breaking down carbohydrate and sugar molecules, the mitochondrion generates energy. The chloroplast, which takes light energy and converts it into chemical energy, uses the mitochondria as a backup when there is no light to obtain energy from. In the end, the plant cell features all sorts of unique

Factors That Influence Senior School Students’perception of Biology in Ilorin-South, Kwara State by Salam, Wahab Adeiza 10/25pa044 a Project Submitted to the Department of Science Education, Faculty of Education,

...CHAPTER ONE INTRODUCTION Background to the Problem Education has been very important through the ages and it can be defined as an organized and sustained instruction designed to communicate a combination of knowledge, skill and understanding valuables for all activities of life. Numerous groups during this century have identified what they believe the goals of education should be. One of the most widely cited reports is that of the commission on the reorganization of secondary education which in 1918 stated the goals of education as the seven cardinal principles: health, command of fundamental processes, worthy home membership, vocation, citizenship, worthy use of leisure and ethical conduct. Although neither science nor any of the other school subjects was included as one of the seven principles, the role and importance of science in achieving the seven cardinal principles is obvious. The world is fast becoming scientific in thinking and behaviors that without good knowledge of science, it might be difficult for people to adequately function in it. The purpose of exposing children to science instruction right from primary school level is not necessarily to turn them into scientist per se but to provide favorable scientific attitudes of ‘finding out’ and ‘hands-on‘ and to enable them raise questions about things that intrigue them. In a study on the impact of science on the society, Bertrand & Russell (1952) have shown that our time is an age of science. Science...

...Clinical Notes The Visible Human Project p. 7 Homeostasis and Disease p. 13 An Introduction to Studying the Human Body This textbook will serve as an introduction to the inner workings of your body, providing information about both its structure and its function. Many of the students who use this book are preparing for careers in health-related fields—but regardless of your career choice, you will find the information within these pages relevant to your future. You do, after all, live in a human body! Being human, you most likely have a seemingly insatiable curiosity—and few subjects arouse so much curiosity as our own bodies. The study of anatomy and physiology will provide answers to many questions regarding the functioning of your body in both health and disease. Although we will be focusing on the human body, the principles we will learn apply to other living things as well. Our world contains an enormous diversity of living organisms that vary widely in appearance and lifestyle. One aim of biology—the science of life—is to discover the unity and the patterns that underlie this diversity, and thereby shed light on what we have in common with other living things. Animals can be classified according to their shared characteristics, and birds, fish, and humans are members of a group called the vertebrates, characterized by a segmented vertebral column. The shared characteristics and organizational patterns provide useful clues about how these animals have evolved over time...

The Biology of Leadership

...The biology of leadership The relation between leadership, psychopathy and hormones Master thesis Economics and Business 8th of August 2012 Name student: Ricardo Westendorp Student number: 294819rw Supervisor: Wouter van den Berg The biology of leadership PREFACE Around October, 2011, I started looking for a subject to graduate on, when a neuro-economical subject, involving the connection of leadership to psychopathy and hormones, crossed my path. I had to jump into it, because this subject matched the field I am interested in. Now, 8 months later, I present you my final work and I have enjoyed working on it. I have to be honest, this product would not have been able to be written if it wasn’t for the help of certain people. Therefore, I would like to use this section, to show my gratitude to some people, that helped me along the way. First of all, I thank the Erasmus School of Economics, for providing the financial support for this research. This research would definitely not have been possible, without the financial support of the ESE. Secondly, I would like to thank my supervisor, Wouter van den Berg, who has supported me, guided me and who has contributed intellectually. I would also like to thank Kashin Hau, who has made great contributions to the construction of the leadership questionnaire. Also, I would like to thank Sarstedt, who provided 500 saliva tubes. I am very thankful for the help of my parents. A great contribution has been made by my parents, Wim Westendorp...

...PART I THEORY, SCHOOLS AND PRACTICE 1 Schools of Thought in Strategic Management: Fragmentation, Integration or Synthesis Tom Elfring and Henk W. Volberda Over the last thirty years, strategic management has become established as a legitimate field of research and managerial practice (Shrivastava, 1986: 363). In the evolution of strategy research, a diversity of partly competitive and partly supplementary paradigms have emerged. To provide an unequivocal definition would mean ignoring the versatility of strategic management. The choice of a definition and the application of specific strategic management techniques is greatly dependent on which paradigmatic schools of thought in strategic management one prefers. In this book, we will therefore review the various schools of thought and their contribution to the theory and practice of strategy. A school of thought is understood to be the range of thought of a specific group of researchers, which has crystallized within the field of strategic management (Brown, 1993). In other words, a school of thought can be seen as an institutionalized paradigm. Besides reflecting on the variety of schools in strategy, we will also sketch out new promising directions in strategy research and practice. Although some strategy scholars have argued that the achieved multiformity in schools of thought signifies an enrichment of the research within the field of study (cf. Mahoney, 1993), other scholars from related disciplines complain about...

Psychology of Education

...EDUCATIONAL PSYCHOLOGY: A DEFINITION AND KEY CONCEPTS It seems too simple to say that educational psychology is the psychology of learning and teaching, and yet a majority of educational psychologists spend their time studying ways to describe and improve learning and teaching. After reviewing the historical literature in educational psychology, Glover and Ronning (1987, p. 14) suggested that educational psychology includes topics that span human development, individual differences, measurement, learning, and motivation and is both a data-driven and a theory-driven discipline. Thus, our definition of educational psychology is the application of psychology and psychological methods to the study of development, learning, motivation, instruction, assessment, and related issues that influence the interaction of teaching and learning. This definition is broad because the potential applications of educational psychology to the learning process are immense! Today educational psychology is a vital discipline that is contributing to the education of teachers and learners. For example, Jerome Bruner, an enduring figure in educational psychology, recently noted the need to rethink our ideas of development, teaching, and learning and the interactions among them. Specifically, Bruner (1996) urged educators and psychologists to see children as thinkers, and stated: No less than the adult, the child is thought of as holding more or less coherent "theories" not only about the world but about...
