Cell Biology: Study Guide
Bio 115 Exam 1 Study Guide
These topics will be on the exam.
▪ What are the tenets of cell theory? • Cells are the basic structural and physiological units of all living organisms. • Cells are both distinct entities and building blocks of more complex organisms. OR • All living organisms are composed of one or more cells, Cells are the basic units of structure and function in an organism, and Cells come only from the reproduction of existing cells. OR • All cells come from preexisting cells. • All cells are similar in chemical composition. • Most of the chemical reactions of life occur in aqueous solution within cells. • Complete sets of genetic information are replicated and passed on during cell division. • Viruses lack cellular structure but remain dependent on cellular organisms. ▪ What is homeostasis? • The maintenance of a steady state, such as a constant temperature or a stable social structure, by means of physiological or behavioral feedback responses ▪ Know the levels of organization of life from the lowest to the highest levels
Atoms>molecules>organells>cells>tissues>organs>organisms/individuals>populations>communities>ecosystems
▪ Genome distance and common ancestors
Genome: The complete DNA sequence for a particular organism or individual ▪ What are the 3 domains?
1)archaea ,bacteria, species ▪ Heterotrophs vs. autotrophs
Heterotrophs: (humans) An organism that requires preformed organic molecules as food
Autotrophs: (plants) An organism that is capable of living exclusively on inorganic materials, water, and some energy source such as sunlight (photoautotrophs) or chemically reduced matter ▪ What does the null hypothesis say and how does that relate to control and experimental group outcomes? ▪ Know how to determine the number of protons, neutrons, and
