BILD 1: The Cell – Course Introduction and Foundations of Cell Biology

Course Overview and Structure

Introduction to BILD 1: The Cell

BILD 1 is an introductory college-level biology course focused on the cell, its structure, function, and foundational biological concepts. The course is designed for students new to college biology and those interested in understanding how living systems operate at the cellular level.

• Target Audience: Students without prior college-level biology and those excited to learn biology.

• Course Philosophy: Emphasizes active learning, peer discussion, and application of knowledge rather than rote memorization.

• Learning Pods: Students work in small groups for discussion, problem-solving, and support.

Course Components

• Lecture Slides: Core content delivery and in-class activities.

• Learning Catalytics: In-class participation using digital devices for concept questions.

• Discussion Sections: Collaborative problem-solving and application of concepts.

• Mastering Biology: Online homework assignments for practice and reinforcement.

Foundational Concepts in Cell Biology

Organizing Principle: Structure and Function

At every level of biological organization, there is a relationship between structure and function. Understanding this relationship helps explain how biological systems operate and adapt.

• Structure: The physical arrangement or organization of biological molecules, cells, or systems.

• Function: The specific role or activity performed by a structure.

• Example: The double-helix structure of DNA enables it to store genetic information and replicate efficiently.

Five Core Concepts of Biology

• Structure and Function

• Information Flow

• Transformation of Energy and Matter

• Systems

• Evolution

These concepts provide a framework for understanding all biological phenomena.

Cell Theory and Definition of Life

Cell Theory is a fundamental concept in biology that defines the properties of cells and life:

• All living organisms are composed of one or more cells.

• The cell is the basic unit of structure and organization in organisms.

• Cells arise from pre-existing cells through division.

Definition of Life (Structure-based): The simplest collection of matter considered to be alive is the cell.

Why Cell Biology Matters: Disease and Dysfunction

• Cell dysfunction can lead to disease. Examples include:

• Dysfunction in excreting waste → build-up of waste products

• Dysfunction in bone growth → achondroplasia

• Dysfunction in sensing → diabetes

• Dysfunction in duplication → cancers

Cellular Components and Types

Universal Features of All Cells

• Plasma membrane: Outer covering that separates the cell's interior from its environment.

• Cytoplasm: Jelly-like region containing cellular components.

• DNA: Genetic material of the cell.

• Ribosomes: Particles that synthesize proteins.

Types of Cells: Prokaryotes vs. Eukaryotes

Feature	Prokaryotes	Eukaryotes
Examples	Bacteria, Archaea	Animals, plants, fungi, amoebas
Nucleus	No membrane-bound nucleus	Has membrane-bound nucleus
Organelles	No membrane-bound organelles	Has membrane-bound organelles
Size	Usually smaller, single-celled	Usually bigger, often multicellular
Analogy	Simple bag	Bag of bags

Prokaryotic Cell Structure

• DNA: Located in the cell, but not enclosed in a nucleus.

• Ribosomes: Present, but no membrane-bound organelles.

• Membrane: Encloses the cell.

Eukaryotic Cell Structure

• DNA: Contained within a nucleus.

• Membrane-bound organelles:

  • Chloroplasts: Photosynthesis (plants and algae).

  • Mitochondria: Energy production from sugar.

  • Endoplasmic reticulum & Golgi apparatus: Protein and lipid processing.

  • Lysosome: Breakdown of cellular waste.

Structure of Viruses

• Proteins: Form the outer shell (capsid) and sometimes additional structures.

• Genetic Material: Can be RNA or DNA (e.g., SARS-CoV-2 has RNA).

• Key Features: No ribosomes, no energy metabolism, cannot grow independently of host cells.

Viruses are not considered living cells because they lack the machinery for independent metabolism and reproduction.

Learning Strategies and Course Success

How to Succeed in BILD 1

• Reach out to instructional staff when confused.

• Keep up with weekly assignments.

• Make connections between course content and real-world applications.

• Focus on understanding and applying concepts, not just memorization.

Active Learning and Peer Discussion

• Peer discussion improves understanding and performance on concept questions.

• Active learning involves engaging with material, asking questions, and working collaboratively.

Study Tips for Textbook Reading

• Preview: Skim chapter features (headings, figures, summaries) before reading.

• Activate Prior Knowledge: List what you already know about the topic.

• Identify Main Ideas: Focus on first sentences and key features.

• Take Notes: Write down main points and questions as you read.

• Summarize: After reading, summarize the main ideas in your own words.

Learning Pod Agreements and Collaboration

Participation and Communication

• Organize teamwork and rotate group roles.

• Commit to regular group meetings and ensure all voices are heard.

• Establish communication methods (e.g., text, email, Slack).

• Set ground rules for discussions and conflict resolution.

Meetings, Conduct, and Deadlines

• Ensure respectful and supportive group interactions.

• Assign rotating roles to validate all contributions.

• Set expectations for meeting attendance and assignment deadlines.
