Throughout history, this natural science has been given the task of answering essential questions about the origin of life and its fundamental laws. In that sense, its study is fascinating and is the basis of many other sciences that feed on it to advance their own findings. Biology is the science that studies all living organisms on the planet, from the microscopic to the largest.
It encompasses all kingdoms: human, animal and plant. Each one of vital importance to preserve the world as we know it. The importance of this natural science lies in the fact that it explains how life develops on earth, its origin, evolution and even its possible death.
It is also in charge of studying the natural laws that govern life and how to improve it, collaborating with branches such as ecology, medicine or chemistry. Its theoretical principles feed many other important disciplines. Some branches of biology are: microbiology , biotechnology , marine biology , zoology , botany , genetics , among others. Biology is not a totally independent science, since it also feeds on other elementary sciences such as mathematics, physics and chemistry, mainly.
Its study is based on the scientific method. It explains the development of living organisms in the following way: Through a metabolic process, the internal condition of organisms is maintained in equilibrium, due to different chemical reactions of nutrition and waste. Likewise, there is a relationship with the environment, reacting to its stimuli.
Thanks to biology, crucial discoveries have been made in the history of mankind, such as the case of penicillin and vaccines, which have saved so many lives to date. Also, the future seems to advance thanks to molecular biology that contributes to the genetic modification of food.
For all these reasons and many more you should take a look at our collection of free biology books in PDF format. We know that you are passionate about this science that is indispensable to continue walking on this planet and, consequently, we wanted you to increase your knowledge about it.
Animal biology is the science that deals with the study of what is called the Kingdom Animalia. This kingdom comprises all multicellular organisms. And which take energy through the digestion of food and also contain cells that are organized into tissues. This is different from plants, which produce their nutrients from inorganic substances through the process of photosynthesis.
Certain chapters and paragraphs are clear and contain enough information. However, most of the text does not contain enough information, largely due to the fact that this book is more like a summary of various topics in biology, not a real textbook.
The text is not consistent in terms of style, formatting, clarity, and information provided. For instance, only practice questions are provided for a couple of topics. The text uses a bullet point style, which makes the modularity very clear. However, by doing so, lots of information is omitted. The topics are divided into chapters only. It can be improved if the chapters are organized by units. There are some grammatical errors, such as misspellings, extra words or numbers, and incorrect use of plurals.
Formats are not consistent. This book summarizes the main concepts in general biology. It can be used for preview and review purposes. The text is easy to read. This is not a comprehensive text. If all of the topics that are missing from this text were included in this review, the review would be as long as the text.
The PDF is less than pages long for what is typically taught in two one-semester Comprehensiveness rating: 1 see less. The PDF is less than pages long for what is typically taught in two one-semester classes. Sufficient detail and background information is not provided. The entire PDF only includes six figures. In particular, information on diversity is incomplete with the majority of taxonomic levels and categories missing. For example, in Chapter 24 Chordates, information on Class Osteichthyes consists of a couple of sentences on Subclass Sarcopterygii.
Ray-finned fishes are not included. Only one half page of information is provided on Class Aves. Class Mammalia is covered in less than one page. Section Developmental biology, comparative physiology, ecology at any level , behavior, endosymbiosis, plant anatomy and plant physiology are a few of the topics absent from the PDF. The glossary is half of a page with many definitions missing. No index is included.
Text content is not accurate, error-free and unbiased. Very little organismal and diversity of life information is provided. Unfortunately, adequate and appropriate quantity of information is not provided for any topic. Proof reading did not occur. Under the section The PDF is outdated and no longer relevant. An incomplete and outdated classification of Kingdom Animalia is used. Important plant, fungi and protist phyla are missing as are milestones in animal evolution and characteristics that allowed plants to colonize land.
The minimal amount of biotechnology information included in the PDF is also outdated. The PDF is highly inconsistent. Scientific and genus names frequently appear in regular font neither italicized nor underlined and capitalization is not consistent. A few sections include complete sentences and paragraphs and the remaining sections contain no text or only bulleted lists. The majority of chapters do not practice questions. If practice questions are included, answers to questions are not consistently included, if at all.
In some sections, references made to pages and figures in an unnamed textbook. Text organization is not logical. The text is not divided into units but would benefit by organization into units rather than using placeholder chapters as is used for Chapter 1 Getting Started, Chapter 6 Cells, Chapter 15 Genetics and Chapter 25 Tissues and Systems. No text included in these placeholder chapters. Information is not logically organized. For example, Chapter 13 on Photosynthesis includes unrelated sections on prokaryote cell division, eukaryote chromosomes, chromosome organization no text included , human karyotype stained by chromosome paints no text included , human chromosomes a quarter page with a bulleted list , mitotic cell cycle three bullets and one text box consisting of one sentence , replicated human chromosomes no text included , mitosis half page of information , plant mitosis one quarter page , controlling the cell cycle, cancer and mutations and cancer no text included.
The glossary Chapter 34 is half of a page with some terms undefined. The list of figures does not correspond to the six figures included in the text. Some of the links in the footnotes connect to Wikibooks pages that do not contain any information. After connecting to a Wikibooks link, clicking the back arrow brings you to the beginning of the PDF, not to the section you were reading. Navigation between footnotes and text is cumbersome.
The text is filled with misspellings, incorrect word use, jargon, incorrect use of plurals, grammatical errors, incomplete sentences and statements without explanation or support.
Considering the brevity of information provided the text is not culturally sensitive. This is not a textbook. The information provided is incomplete and outdated and is little more than an incomplete and unedited draft of course notes. This open book is very comprehensive, however, I believe that the context of the book may be too comprehensive. Moreover, the text covers very broad fields of biology that students may not be able to grasp.
However, the text is not in a However, the text is not in a traditional style, meaning that it contains less than pages.
Therefore, students will not get in depth knowledge. Some chapters appear to be incomplete. The book appeared to be accurate. More specifically, the paragraphs, sentences, and phrases are very short resulting in great accuracy. Moreover, students can learn many topics very quickly and efficiently. Lastly, I noticed some mistakes but they were minor problems. Importantly, this book is very up-to-date and can be updated quickly if authors want.
On-the-other-hand various chapters seem to be incomplete or too short i. But the unique style of this book enables authors to update information easily. The text was written very clearly, while the book is very short. Tags: cell biology Free books. Sachin Chavan is working as Ph.
