Cov protists tuaj yeem muab faib ua ib qho ntawm peb pawg tseem ceeb, tsiaj -zoo li, cog -like, thiab kab mob -zoo li. Muab faib ua ib qho ntawm peb pawg yog ua raws li lub cev hom kev yug me nyuam, kev noj haus, thiab kev txav mus los.

Tsis tas li ntawd, peb pawg twg yog cov neeg tawm tsam cais tawm?

  • Tsiaj-zoo li protists, uas yog heterotrophs thiab muaj peev xwm txav mus los.

  • Fungi-zoo li protists, uas yog heterotrophs, thiab lawv muaj cov hlwb nrog cov phab ntsa ntawm tes thiab rov tsim dua los ntawm kev tsim cov spores.

Ib sab saum toj no, vim li cas protists suav tias yog pawg Polyphyletic? Teb: Protists raug suav hais tias raws li polyphyletic pawg ntawm cov kab mob raws li lawv cov keeb kwm tsis yog los ntawm cov poj koob yawm txwv.
