Quick Review of Cell Organelles and Structures

Introduction

• Purpose: Quick review of cell organelles and structures
• Format: Guess the organelle based on clues given
• Rating system: Organelle importance rated on a scale of 1 to 10

Cell Membrane

• Description: External structure present in all cells (prokaryotic and eukaryotic)
• Function: Controls movement in and out of the cell; important for homeostasis
• Rating: 8/10 - Important but not cute

Cell Wall

• Description: Found in most prokaryotic cells and some eukaryotic cells (e.g., plant cells)
• Function: Provides structure and protection to the cell
• Rating: 6/10 - Not a fan of walls

Centrioles

• Description: Present in animal cells (not in plant cells); come from centrosome
• Function: Involved in cell division (spindle fibers)
• Rating: 4/10 - "Rude" function of pulling chromosomes around

Chloroplast

• Description: Found in plant cells
• Function: Site of photosynthesis; makes sugar
• Rating: 10/10 - Considered cute (like a cinnamon roll)

Cytoplasm

• Description: Present in all cells; everything inside the cell except for the nucleus
• Function: Supports organelles; contains cytosol (jelly-like substance)
• Rating: 2/10 - Considered "extra"

Endoplasmic Reticulum (ER)

• Description: Found in eukaryotic cells (plant and animal)
• Function: Highway for materials; processes molecules
  • Rough ER: Has ribosomes, makes proteins
  • Smooth ER: Makes lipids and detoxifies
• Rating: 6/10 - Confusing nickname

Golgi Apparatus

• Description: Found in eukaryotic cells
• Function: Modifies, sorts, and packages materials for delivery
• Rating: 9/10 - Fun to say

Lysosome

• Description: Found in eukaryotic cells; often debated in plant cells
• Function: Contains enzymes for digestion of substances
• Rating: 10/10 - Powerful digestive organelle

Mitochondrion

• Description: Found in eukaryotic cells
• Function: Produces ATP in cellular respiration
• Rating: 2/10 - Overused meme about being the powerhouse of the cell

Nucleus

• Description: Found in eukaryotic cells
• Function: Houses DNA and controls cell activities
• Rating: 8/10 - Easy to draw, houses cool stuff

Ribosome

• Description: Found in all cells
• Function: Makes proteins
• Rating: 9/10 - Appreciated for solid work ethic

Vacuole

• Description: Found in eukaryotic cells (plant and animal)
• Function: Stores materials (water, proteins, waste)
• Rating: 3/10 - Vague storage function

Conclusion

• Reminder to review organelles for quizzes/tests
• Importance of organelles: Dysfunction can lead to diseases (e.g., endoplasmic reticulum disorders, mitochondrial disorders)
• Call to continue curiosity and exploration of science
