C. the use of organisms to remove pollutants from the environment The infundibulum catches and channels the released eggs; it is the wide distal (outermost) portion of each fallopian tube. Which is the function of the Fimbria? Cell division in prokaryotic cell and eukaryotic cell is also different. Some can do photosynthesis the way chloroplasts do.

Transduction C. spirochetes Pili are longer than fimbriae and there are only a few per cell. Genetic variation in bacterial populations cannot result from No clear consensus but some consider fimbrae as non-flagellar protein filament encoded for by chromosomal genes while pili are encoded for by plasmid genes. What is the function of fimbriae? The main function of the fallopian tube is to transport the egg from the ovary to the uterus. 5 What is a role of the streptococcal fimbriae?
