Prokaryotic Cells Notes

Prokaryotic Cells

Introduction to Prokaryotic Cells

• Objective: To explore prokaryotic cells.
• Success Criteria:
  • Identify prokaryotic cells using existing knowledge.
  • Draw and label a prokaryotic cell.
  • Compare prokaryotic and eukaryotic cells.
• Starter Activity: Classify cells and suggest what a prokaryotic cell is.
• Challenge: How do prokaryotes affect us in daily life?

Cell Types

• Prokaryotic Cells: Do not contain a nucleus (e.g., bacteria).
• Eukaryotic Cells: Contain a nucleus.
• Examples of cell types:
  • Plant cells
  • Animal cells
  • Prokaryotic cells

Key Components of Prokaryotic Cells

• Keywords: prokaryotic, eukaryotic, cell, chromosomal DNA, plasmid, cell wall, cell membrane, cytoplasm, nucleus, flagella, capsule.

Drawing and Labeling a Prokaryotic Cell

• Support Keywords: chromosomal DNA, cell wall, slime capsule, cell membrane, plasmid, cytoplasm, flagella.
• Challenge: Describe the function of each organelle.

Comparing Prokaryotic and Eukaryotic Cells

• Copy and complete a table to compare prokaryotic and eukaryotic cells.
• Support: Comparing organelles in animal, plant, and bacterial cells.
  • Organelle presence in different cell types:
    • Nucleus
    • Cell membrane
    • Chloroplasts
    • Vacuole
    • Cytoplasm
    • Cell wall
    • DNA free in the cytoplasm
• Challenge: Write a paragraph comparing eukaryotic and prokaryotic cells.

Table Completion and Comparison

• Complete the table to show the presence or absence of organelles in different cell types.
• Peer assessment of comparison paragraphs.

Plenary

• Choose an activity to reflect on what has been learned.
• Review the success criteria:
  • Identifying prokaryotic cells.
  • Drawing and labeling a prokaryotic cell.
  • Comparing prokaryotic and eukaryotic cells.
