Protists are unicellular eukaryotes, whereas Eubacteria and Archaebacteria are unicellular prokaryotes.
Eubacteria and Archaebacteria belong to kingdom Monera; whereas Protists belong to kingdom Protista.
All Monerans have prokaryotic cell structure. Protists have eukaryotic cell structure and are unicellular.
Protists either lack cell wall or have cell wall made up of cellulose.
Eukaryotes have cell wall made up of peptidoglycan or murein.
In Archaebacteria cell wall lacks peptidoglycan but contains proteins and non-cellulosic polysaccharides.
Protists have typical sexual reproduction involving fusion of gametes. In Eubacteria and Archaebacteria typical sexual reproduction is absent.
Cell division is mitotic type in Protists and amitotic in Eubacteria and Archaebacteria.
1. With respect to oxygen requirements, an <u>aerobe </u>can use gaseous oxygen and possesses enzymes to process toxic oxygen products.
<h3>
What are enzymes?</h3>
Proteins called enzymes aid in accelerating our bodies' chemical reactions, or metabolism. Some compounds are created, while others are broken down. Enzymes are a component of all life. Enzymes are created by our bodies spontaneously.
2. Expanding on this classification, an <u>obligate </u>aerobe cannot grow without oxygen.
3. Still other organisms, called<u> facultative anaerobes</u>, metabolize by aerobic respiration but can adapt to anaerobic environments.
A facultative anaerobic organism is one that can switch from aerobic respiration to fermentation in the presence of oxygen to produce ATP.

This is all i know about caves: Caves are large, natural holes beneath the surface of the earth. Underground passages and caves are found in rocky landscapes across the world. They are found in areas with a lot of limestone, a common type of rock. They can be created in various ways, but most caves are hollowed out of rock by water.
Geological processes are events that occur on a geological timescale ranging between millions of centuries, hundreds of meters, and thousands of kilometers. Compare this to the everyday models from physics and engineering operated at laboratory units an
