. There are diverse forms of life on earth ranging from the invisible microscopic living things to the gigantic life forms. . To accomplish this goal it’s necessary that Lecture Notes for Biology 101: An Introduction to Science and Biology for Non-Majors Instructor David L. Alles Course Outline The organization of this course has been driven by the goal of providing non-majors with a coherent picture of modern biological knowledge. . . stinging insects.These are bottles used for keeping collected specimen.

These characteristics are discussed below.We have defined biology as the study of living things. %PDF-1.3 %���� 0000002200 00000 n It is divided into two broad branches.Within the two branches, there exist even smaller branches because the branches (botany andThe study of biology is very important. 0000001592 00000 n The role of human beings in shaping the environment is also investigated in biology.In summary, biology deals with the study of origins, types, nature, growth, development, interactions and maintenance of all life forms on earth.Biology is such a broad field of knowledge. We find two types of life in nature. 0000002034 00000 n . The Greek word bios means “life” , and -logy means “study of.” It is a vast subject with many subdisciplines that concentrate on specific aspects of biology. . .

The term Biology comes from two Greek words (bios means life and logos means knowledge). A hand lens is a common magnifying lens used in the laboratory. It aims at explaining the living world in terms of scientific principles.It is important to note, however, that living things interact with the non living things in the environment as well. Biology, therefore also entails the study of non living things as well. The living things or parts of living things that are used for biological study are called specimens. 0000005233 00000 n It aims at explaining the living world in terms of scientific principles. In s… Accordingly Biology has been divided into two branches: Botany and Zoology. . . It is important to note, however, that living things interact with the non living things in the environment as well. The magnifying power of a lens shows how many times the image will be enlarged compared to the object.-To use a magnifying lens, place the object to be enlarged on the bench. 0000001658 00000 n Biology l From the greek word βίος = life l Timeline: l 1683 – discovery of bacteria l 1858 – Darwin’s natural selection l 1865 – Mendel’s laws l 1953 – double helix suggested by Watson-Crick l 1955 – discovery of DNA and RNA polymerase l 1978 – sequencing of first genome (5kb virus) l … . 0000001867 00000 n Biology is a branch of science that deals with the study of living things. INTRODUCTION TO THE CELL Both living and non-living things are composed of molecules made from chemical elements such as Carbon, Hydrogen, Oxygen, and Nitrogen. . The magnifying power of the hand lenses is always indicated on the lens e.g. 0000007940 00000 n The main goal of this chapter is to provide basic information about types and design of microscopes, as well as about The word “biology” means the “study of life.” Biology—The study of life. Hold the magnifying lens on one hand and while closing one eye, move the lens towards the object until the image comes into clear focus.While collecting specimen for observation, a biologist should play close attention to the following:Most possess chlorophyll which gives them their green colour. Contents 1 GettingStarted 3 2 Biology-TheLifeScience 5 2.1 Characteristicsoflife . The knowledge acquired from this study can benefit an individual in myriad ways. . . Biology is the science of living beings. For effective study, a biologist may have to collect some living things or some parts of living things for observation and analysis. They are of different sizes depending on the size of the specimen being studied.This is used to enlarge small objects. The role of human beings in shaping the environment is also investigated in biology. One is plant while the other is animal.
