Cell Theory and Transport Quiz

Cell Theory and Organelles

• Cell theory's three principles: All living things are made of cells, cells are the basic unit of life, and cells come from pre-existing cells.
• Prokaryotic vs. Eukaryotic cells should be differentiated with a Venn diagram showing characteristics common to both, and unique to each.
• Plant vs. animal cells: plant cells have unique structures, like cell walls, chloroplasts, and large vacuoles, not found in animal cells.

Cell Transport

• Dynamic vs. static equilibrium: dynamic equilibrium involves continuous movement while static equilibrium is stable. Homeostasis maintains equilibrium.
• Stimulus response and homeostasis: A stimulus triggers a response that maintains homeostasis, i.e., a regulated internal environment.
• Feedback loops: Positive feedback loops amplify a response, while negative feedback loops reverse a response (e.g., regulation of body temperature).
• Cell membrane role in homeostasis: The cell membrane regulates what enters and exits the cell to maintain homeostasis.
• Active vs. passive transport: Active transport requires energy, while passive transport does not. Six types of transport (exocytosis, endocytosis, facilitated diffusion, osmosis) and examples of substances transported should be included.
• Hypotonic, isotonic, and hypertonic solutions and the effect of each on cells. A picture illustrating the differences between the solutions could be helpful.
• Classify transport types as active or passive based on diagrams/descriptions. Classify solutions as hypertonic, hypotonic, or isotonic.

Cell Cycle and Cancer

• Order of events from egg to embryo including examples of cell specialization and stem cells.
• Levels of organization: From cells to organs to organ systems to organisms (increasing complexity).
• Purposes of cell division: Growth and repair.
• Phases of the cell cycle: Stages in detail, emphasizing the role of each phase, including the subphases of interphase, and mitosis (PMAT). The importance of interphase is critical in this case.
• Cytokinesis (plant vs. animal): The process in which the cytoplasm divides during mitosis /meiosis to generate two daughter cells.
• Checkpoint regulation and apoptosis ensure proper cell division and prevent cancerous cells with the explanation of the regulating role.
• Definition of tumours and the difference between benign and malignant tumours.
• Causes of cancer: A summary of potential cancer causes.
• Mitosis stages: Identifying the stage of mitosis based on descriptions or diagrams and evaluating consequences of failures in cell cycle.
• Differences in plant and animal cytokinesis.

Vocabulary

• Include definitions for concepts like homeostasis, solute, solvent, solution, concentration, differentiation, stem cells, cell cycle, chromosome, gene, and other terms in the provided list.
