Zoology Lecture 5

Reynolds number Re is a ratio of the inertial forces to viscous forces

Re= pVL/micro

• Lobopodia
• Axopodia
• Filopodia

A whole bunch of blunt finger looking things used in motion

.fingerlike; filopodia are slender and tapering, occasionally forming simple, branched networks; reticulopodia, found in the foraminiferans, are branching filaments that fuse to form food traps;and axopodia, characteristic of the actinopods, are long and sticky (like reticulopodia) but radiate singly and have a stiff, internal rod composed of numerous microtubules

For motion and forming food vaculous

• Benificial
• Harmful
• Harmless

Mutualism - Each symbionit will derive a benifit from the relationship.

Commensalism one organism benifits while the other is unaffected

• 1. Polymerization of actin
• 2. depolymerization of actin

Metazoans generally are not able to breakdown cellulose. so Trichomonas lives inside the guts of termites to do it for them.

Trichomonas - resides within termite gut to help breakdown cellulose

Yes humans have trichomonas.Trichomonas reside within the mouth of humans

Bacteria

Trypanosome brucei

• 8. Trympanosomas multiply in salivary gland of tsetse fly which are now ready to be transfered to a human host

When they reside within the human hosts lymph and spinal fluids. not a good thing id imagine
