- Nucleus
- Vacuole
- Cell wall
- Mitochondria
- Golgi Apparatus
- Cell membrane
- Chloroplast

Learning Targets
- Evidence that cells make up living things
- How cell structure determines the structure of living things
- Special structures within a cell
- How different cell parts contribute to cell function
- How animal cells differ from plant cells
Questions
- Cell structure vs. function: Structure refers to the organelles, while function describes their roles. For example, the nucleus stores DNA, a specific structure.
- Cell Theory: All life is composed of cells, the basic unit of structure and function, and all cells originate from existing cells.
- Cell Discoverer: Robert Hooke
- Three Principles of Cell Theory: All living things are composed of cells; cells are the basic units of structure and function in living things; all cells come from pre-existing cells.
- Microscope Use: Review page 68 for microscope techniques. Magnification and resolution are key concepts. Magnification is the appearance of size change using a lens or optics; resolution is the clarity of the image.
Additional Organelle Concepts
- Organelle Definition: A tiny, specialized structure within the cell that performs a specific function.
- Unique Plant Cell Organelles: Cell wall, chloroplasts, and large central vacuole are unique or absent in animal cells.
- Cell Function and Organization: Cells work in teams as tissues, tissues form organs, organs contribute to organ systems, and organ systems form the organism.
Specialized Cells
- Examples: Nerve cells, heart cells, and skin cells
- Organization Levels: Atoms, molecules, cells, tissues, organs, organ systems, and organisms are the different levels
Organization and Specialization
- Levels become more specialized as the level of organization increases
Living Cell Analogy
- A living cell can be seen like a factory, school, or house.
Cell Types and Organelles (Diagram Analysis)
- Cell Type: Identify the plant cell using evidence such as the chloroplasts and cell wall.
- Organelles: List the organelles present (e.g., ER, ribosomes, Golgi, vacuole, cell membrane, cell wall, chloroplasts, nucleus, and mitochondria).
Mitosis
- Cell Division Reasons: Growth, repair, and reproduction
- Cell Cycle Parts: Interphase, Mitosis (prophase, metaphase, anaphase, telophase), and Cytokinesis
- Mitosis Stages: Details of events in each phase. Use the notes provided to highlight.
- What Cell Division Does: Makes new daughter cells identical to the parent cell.
Homeostasis
- Maintaining Balance: Homeostasis is maintaining a stable internal environment.
- Examples: Shivering in cold weather to regulate temperature.
- Cell Activities: Cells need to make new cells; get or use energy, exchange materials, and get rid of waste.
Active and Passive Transport
- Active transport uses energy; moves molecules from areas of low concentration to areas of high concentration (against the concentration gradient)..
- Passive transport doesn't use energy; moves molecules from areas of high concentration to areas of low concentration (down the concentration gradient).
Osmosis
- Definition: The diffusion of water across a selectively permeable membrane.
- Water Movement: Water flows into or out of the cell depending on solute concentration.
Endocytosis and Exocytosis
- Endocytosis: The process of taking large particles into the cell
- Exocytosis: The process of releasing substances from the cell
Photosynthesis and Cellular Respiration
- Photosynthesis: Uses water, carbon dioxide, and light energy to produce glucose and oxygen; typically occurs in chloroplasts.
- Cellular Respiration: Breaks down glucose to release energy in the form of ATP and produces water and carbon dioxide; typically occurs in mitochondria.
- Relationship: Reactants are products of the other process, making them interconnected.
