Question

Observation of flagella in the biflagellate alga, Chlamydomonas reinhardtii, indicates that particles move toward the tips of flagella at a rate of 2.5 mu m/min, but the particles moving back toward the base of flagella move at 4 mu m/min. How do you explain this difference in rate of movement? Particles use different motors with different velocities to move outward and inward. The gravity increases the rate of movement toward the base of flagella. There are different pressures at the tips of flagella and at the base of flagella. There are different concentrations of the particles at the tips of flagella and at the base of flagella.

Explanation / Answer

Particles use different motors with different velocitied to move outward and inward,

The gravity invreases the rate of movement toward the base of flagella.

There are differen concentrations of the particles at the tips and at the base of flagella.
