Chapter 1 Study Guide – Foundations of Biology

Q1. Name and briefly describe the 7 things that all living things do.

Background

Topic: Characteristics of Life

This question tests your understanding of the fundamental characteristics that define living organisms. These are often called the "seven properties of life" and are essential for distinguishing living things from non-living things.

Key Terms:

• Metabolism

• Homeostasis

• Growth

• Reproduction

• Response to stimuli

• Organization

• Adaptation/Evolution

Step-by-Step Guidance

1. List each of the seven characteristics that all living things share. Try to recall them from your notes or textbook.

2. For each characteristic, write a brief description (one sentence) explaining what it means. For example, what does "metabolism" refer to in living organisms?

3. Think of an example for each characteristic to help reinforce your understanding (e.g., how do plants show growth?).

Q2. List the levels of the organization of life from smallest to largest.

Background

Topic: Biological Organization

This question is about the hierarchy of biological organization, which helps us understand how life is structured from the simplest to the most complex levels.

Key Terms:

• Atom

• Molecule

• Organelle

• Cell

• Tissue

• Organ

• Organ system

• Organism

• Population

• Community

• Ecosystem

• Biosphere

Step-by-Step Guidance

1. Start with the smallest unit (think chemistry and cell biology basics).

2. List each level in order, moving from the smallest (e.g., atom) to the largest (e.g., biosphere).

3. Make sure you do not skip any intermediate levels (e.g., tissue comes after cells but before organs).

Q3. Compare and contrast eukaryotic and prokaryotic cells. Use the Venn diagram below as a guide, adding the following characteristics: Smaller, Larger, Complex, Simple, Has DNA, Has Membrane-bound organelles, Has a cell membrane (on the outside of the cell).

Background

Topic: Cell Structure and Function

This question asks you to distinguish between prokaryotic and eukaryotic cells, two major cell types, and to identify their similarities and differences.

Key Terms:

• Prokaryote: Cell without a nucleus or membrane-bound organelles

• Eukaryote: Cell with a nucleus and membrane-bound organelles

• Cell membrane: Outer boundary of the cell

• DNA: Genetic material

Step-by-Step Guidance

1. Draw a Venn diagram with two circles: one for prokaryotes, one for eukaryotes, and an overlapping section for similarities.

2. Place each characteristic in the correct section. For example, "has DNA" goes in the overlap, since both cell types have DNA.

3. Think about which features are unique to each cell type (e.g., membrane-bound organelles for eukaryotes).

Q4. What are the three domains of life, and which are prokaryotes? Which are eukaryotes?

Background

Topic: Classification of Life

This question is about the highest level of biological classification, the three domains, and asks you to identify which domains contain prokaryotic and eukaryotic organisms.

Key Terms:

• Domain: The broadest taxonomic category

• Prokaryote: Organisms without a nucleus

• Eukaryote: Organisms with a nucleus

Step-by-Step Guidance

1. Recall the three domains of life (think about the broadest categories in classification).

2. Identify which domains are made up of prokaryotic organisms and which contain eukaryotic organisms.

3. List examples of organisms from each domain to reinforce your understanding.

Q5. What are some examples of eukaryotes? Examples of prokaryotes?

Background

Topic: Cell Types and Examples

This question asks you to give examples of organisms that are eukaryotic and those that are prokaryotic, reinforcing your understanding of the differences between these two cell types.

Key Terms:

• Eukaryote: Organisms with complex cells (nucleus, organelles)

• Prokaryote: Organisms with simple cells (no nucleus)

Step-by-Step Guidance

1. Think of common organisms you know and classify them as eukaryotes or prokaryotes.

2. Remember that all animals, plants, fungi, and protists are eukaryotes.

3. Bacteria and archaea are examples of prokaryotes.

Q6. Order the following steps of the scientific method in order, and describe what they are: Testing a prediction (using an experiment), Making a hypothesis, Drawing a conclusion, Making an observation, Retesting.

Background

Topic: Scientific Method

This question tests your understanding of the steps involved in the scientific method, which is the process scientists use to investigate questions and test hypotheses.

Key Terms:

• Observation

• Hypothesis

• Experiment

• Conclusion

• Retesting

Step-by-Step Guidance

1. Arrange the steps in the logical order that scientists follow when conducting research.

2. Write a brief description of what happens at each step (e.g., what does it mean to make an observation?).

3. Think about how each step leads to the next in the process of scientific inquiry.

Q7. Be able to describe the following parts of an experiment: Independent Variable (IV), Dependent Variable, Constants, Control Group, Experimental group(s).

Background

Topic: Experimental Design

This question is about understanding the different components of a well-designed experiment, which is crucial for interpreting scientific results.

Key Terms:

• Independent Variable (IV): The variable that is changed or manipulated

• Dependent Variable: The variable that is measured

• Constants: Factors kept the same in all groups

• Control Group: The group that does not receive the experimental treatment

• Experimental Group: The group(s) that receive the treatment

Step-by-Step Guidance

1. Define each term in your own words, using examples if possible.

2. Think about how each part functions in an experiment (e.g., why is a control group important?).

3. Try to relate each part to a real or hypothetical experiment for better understanding.

Q8. What is a scientific theory? What has to be done for a concept to be considered a theory?

Background

Topic: Nature of Science

This question asks you to explain what a scientific theory is and what criteria must be met for a concept to be accepted as a theory in science.

Key Terms:

• Scientific Theory: A well-substantiated explanation of some aspect of the natural world

• Evidence

• Peer Review

• Reproducibility

Step-by-Step Guidance

1. Define what a scientific theory is, distinguishing it from a hypothesis.

2. List the criteria that must be met for a concept to be considered a theory (e.g., supported by evidence, tested repeatedly).

3. Think of examples of scientific theories (e.g., cell theory, theory of evolution).
