I need help... paramecium and radial symmetry???!?!?!?!?

Post by munkeyzrox28 » Tue Nov 01, 2005 11:52 pm

:?: yeah...i'm pretty sure i really hate biology...

1) Explain the process of conjugation in PARAMECIUM. How does it differ from the process of conjugation in bacteria?

2) Radial symmerty is found only among animals that live in water.Why is radial symmetry better suited to animals that live in water than to animals that live on land?

Can anyone help? Thanx!

Sam :D

hi sam,
im raju
bacteria is an procariot (organisms with out an nuclear membrane)_ and paramitium is an eukariot(wit nuclear membrane)
hence when two bacterias make an conjugation bridge only a segment of the whole circula dna breaks and enters athe other
when paramisium conjugate there r two nucleus found one large & one small the small one enters the other organisms



usually all te water microbes are free swimmers and they while moving from one place to another they experience a constant density plane and a smooth plane hence their body is radial(cut there body into two at their radius they form two similar copies) and the organism in soil experience different land marks they need to cghange their body structures a lot eg: amoiba
