Biology Chapter 1 Study Guide
Exam: Chapter 1 Study Guide
1. What are the 11 levels of organization? Briefly define each.
Atom - fundamental units of matter, building block of all substances
Molecule - atoms joined in chemical bonds (an association of 2 or more atoms)
Cell - smallest unit of life
Tissue - organized array of cells and substances that interact in a collective task
Organ - structural unit of interacting tissues
Organ System - a set of interacting organs
Multicelled Organism - individual that consists of one or more cells
Population - group of single celled or multicelled individuals of a species in a given area
Community - All populations of all species in a specified area
Ecosystem - A community interacting with it's physical environment through the transfer of energy and materials
Biosphere - the sum of all ecosystems: all regions of Earth where organsims live.
2. List the 5 major features common to all living things.
Made up of cells
Evolution (change over time)
Growth and Development (Cell divison/DNA)
Need for energy and raw materials (Meatabolism)
Response to environment (homeostasis)
3. List 2 different ways living organisms accomplish each of the 5 features above. (the focus here is to recognize how living things differ from one another)
We divide Earth's biodiversity into broad groups based on traits such as having a nucleus (eukaryotes), not having a nucleus (prokaryotes), or being unicellular or multicellular.
4. Be able to explain the difference between Producers and Consumers in paragraph form, and be able to provide an example of each.
Producers are an autotrophic organism capable of producing complex organic compounds from simple inorganic molecules through the process of photosynthesis. Producers make their own food using energy and simple raw materials they get directly from the environment. Example would be plants. All life on earth is directly or indirectly reliant on producers.
Consumers is an organsim that generally obtains food
