Lesson Objectives
- Identify contributions of various scientists to cell theory.
- Explain postulates of cell theory and modern cell theory.
- Curriculum focus: Explain postulates of the cell theory (STEM_BIO11/12-Ia-c-1).
Activity 1: Compare and Analyze
- Analyze pictures to observe differences in cell types.
- Discuss reasons for distinct differences between various types of cells.
Activity 2: Scientist Contributions Table
- Arrange contributions of key scientists related to cell theory:
- Robert Hooke (1665): First to view the cell using a microscope and coined the term "cell".
- Antonie van Leeuwenhoek (1676): Observed the first living cells, referred to as "animalcules".
- Matthias Schleiden (1838): Concluded that all plants are made of cells, emphasizing similar composition.
- Theodore Schwann (1839): Stated that animal cells differ from plant cells and contributed to the understanding of RBCs.
- Rudolf Virchow (1855): Proposed that cells arise from pre-existing living cells, forming the third part of cell theory.
Cell Theory Overview
- Fundamental concept in biology explaining that:
- All living organisms are composed of cells.
- The cell is the basic unit of life.
- All cells arise from other living cells.
Modern Cell Theory
- Builds upon the original cell theory by incorporating new scientific findings and technologies.
- Emphasizes the importance of cellular processes and functions in understanding life.
Activity 3: Personal Application
- Relate concepts of cell theory to everyday life scenarios.
Wrap-up and Enrichment
- Summarize the lesson using a diagram highlighting the postulates of the cell theory and modern modifications.
- Encourage students to study cell parts and their functions in depth as enrichment activity.
