🔹 Lesson 1: Lesson 1 - Approaching the Cell: Understanding Life from a Systematic Perspective

Overview: This lesson aims to guide students to re-examine the cell from a systematic perspective, establishing the core concept that "the cell is the basic unit of life activities." By exploring the structural levels of living systems, the diversity and unity of cells (prokaryotic and eukaryotic), microscope observation practice, and the establishment of cell theory, students will master the scientific thinking of induction and understand the intrinsic logical connection from microscopic cells to the macroscopic biosphere.

Learning Outcomes:

• Recognize that the cell is the basic unit of life activities, and understand the structural hierarchy of living systems.
• By comparing prokaryotic and eukaryotic cells, summarize the unity of cells; master the application of complete induction and incomplete induction.
• Master the operating skills of the high-power microscope, observe and describe the morphological structures of different cells.

🔹 Lesson 2: Lesson 2 - Molecules Composing Cells: The Material Basis of Life Systems

Overview: This lesson aims to explore the material basis of cells, covering the unity and diversity of elements from the inorganic natural world to living systems. It focuses on explaining the structures and functions of six major types of compounds: water, inorganic salts, carbohydrates, lipids, proteins, and nucleic acids. It emphasizes the core structural role of the carbon skeleton in biological macromolecules and introduces experimental methods for detecting major organic components in biological tissues.

Learning Outcomes:

• Explain the main elements and compounds that compose cells, illustrating the unity and diversity between the living world and the inorganic natural world.
• Explain the important roles of water and inorganic salts in cellular life activities.
• Differentiate the types of carbohydrates and lipids and their functions in energy supply and structural composition.

🔹 Lesson 3: Lesson 3 - Basic Structure of Cells: The Precision Life Factory

Overview: This lesson delves into the structural basis of the cell as the fundamental unit of life activities, covering everything from the fluid mosaic model of the cell membrane to the division of labor among various organelles, and the core role of the nucleus as the control center. By learning about the synthesis and transport of secretory proteins and the concept of the endomembrane system, students will understand how different parts of the cell form a precise, coordinated "life factory."

Learning Outcomes:

• Explain the fluid mosaic model of the cell membrane, and recount the historical exploration of the cell membrane's composition and structure through scientific history.
• Differentiate the structures and functions of various organelles (such as mitochondria, chloroplasts, etc.), and master differential centrifugation and high-power microscope observation techniques.
• Explain the synthesis and transport process of secretory proteins, understanding the application of isotope labeling and the significance of the endomembrane system in life activities.

🔹 Lesson 4: Lesson 4 - Material Input and Output in Cells: The Art of Transmembrane Transport

Overview: This lesson focuses on the material transport functions of the cell membrane, primarily exploring how water, small molecules, ions, and macromolecules enter and exit cells. Through the study of osmosis phenomena, plasmolysis experiments in plant cells, and comparisons of transmembrane transport methods, it clarifies that the cell is an open system whose boundary (the cell membrane) precisely controls the input and output of materials via passive transport, active transport, endocytosis, and exocytosis to maintain normal cellular life activities.

Learning Outcomes:

• Be able to explain the principles of osmosis and analyze the phenomena of water movement into and out of animal red blood cells and plant cells.
• Be able to explain the characteristics of passive transport (simple diffusion and facilitated diffusion) and active transport, and distinguish the mechanisms of carrier proteins and channel proteins.
• Be able to explain the processes of endocytosis and exocytosis and their significance for the transport of macromolecules.

🔹 Lesson 5: Lesson 5 - Energy Supply and Utilization in Cells: The Power Source of Life Activities

Overview: This lesson focuses on how cells carry out efficient and orderly metabolic activities through enzymatic catalysis, and deeply analyzes the processes of energy capture (photosynthesis) and release (cellular respiration). Through learning, students will master the nature and characteristics of biological catalysts, understand the logic of material and energy transformation in aerobic and anaerobic respiration, and explore the structural basis of photosynthesis and its response to environmental factors, thereby establishing a view of matter and energy in life.

Learning Outcomes:

• Be able to explain the principle of enzymes lowering activation energy and use the controlled variable method to design controlled experiments to explore enzyme characteristics.
• Be able to explain the processes, similarities, and differences between aerobic and anaerobic respiration, and their applications in production and daily life.
• Be able to explain the types and functions of pigments in green leaves, and detail the light-dependent and light-independent reactions of photosynthesis and their influencing factors.

🔹 Lesson 6: Lesson 6 - The Life Cycle of Cells: Growth, Development, and Totipotency

Overview: This lesson focuses on how cells complete their life cycle through proliferation and differentiation. Content covers the basic concept of the cell cycle, the dynamic process of mitosis (comparing differences between plants and animals), the physical factors limiting cell growth, and the biological essence of cell differentiation and totipotency. Through learning, students will understand how a multicellular organism develops from a single fertilized egg into a complex organism while maintaining genetic stability.

Learning Outcomes:

• Be able to explain the concept of the cell cycle and accurately describe the behavioral characteristics of chromosomes during each phase of mitosis.
• Using model experiment data, clarify that the ratio of cell surface area to volume limits unlimited cell growth.
• Be able to distinguish the similarities and differences of mitosis between animal and plant cells, and describe the characteristics of amitosis.
