Study Notes
Flagella Movement in Cells
- Flagella Function: Used by many cells for locomotion.
- Chlamydomonas: Features an eye spot that influences flagella movement based on light, helping the cell steer toward or away from light sources.
Prokaryotic vs. Eukaryotic Flagella
- Prokaryotic Flagella: Composed of flagellin; anchored by a basal body and rotate to propel the bacterium either forward or backward.
- Eukaryotic Flagella: Made of microtubules; utilize dynein motor proteins for whip-like motion, allowing efficient cell propulsion.
Diversity of Flagella
- Euglenoids: Have two distinct flagella with different functions; one coils around the cell, while the other extends forward for movement.
- Other Algae: Some species possess multiple flagella, such as an eight-flagella configuration that allows rapid swimming.
Cilia in Eukaryotic Cells
- Cilia Structure: Short, hair-like structures prevalent on many Eukaryotic cells; typically numerous and cover extensive areas of the cell surface.
- Functions of Cilia: Facilitate movement and sensory functions; they can swim and create currents for feeding, enabling the capture of nearby organisms.
Mechanical Coordination and Movement
- Paramecium Agility: Utilizes hundreds or thousands of cilia for rapid movement, allowing for effective searching for food.
- Coordinated Beating: Cilia beat in unison, reversing direction to change swimming patterns based on environmental cues.
Cilia in Animal Tissues
- Tissue Functionality: Certain animal tissues, like cultured lung cells, have multiple cilia working in coordination to transport liquid or mucilage over tissue surfaces.
Microtubule Structure
- Core Composition: Both flagella and cilia contain a core of microtubules that can be visualized using polarized light, highlighting structural details.
