Is a caterpillar unicellular or multicellular?
The larvae of all insects is multicellular and not unicellular because the larvae is composed of several different organs and cell types. In order for something to be unicellular, it must contain only one cell.
What substance is made of sugars and peptides and is found in the cell of Eubacteria?
The cell walls of eubacteria contain peptidoglycan.
Prokaryotes do not contain a nucleus or?
membrane-bound organelles
What cell walls contain tetrapeptides?
All prokaryotes
Does eukarya contain prokaryotes?
Yes because i did something about that.
What is the common characteristics among eubacteria?
- unicellular prokaryotes - cell walls contain peptidoglycan - genes lack introns - reproduce asexually by binary - either autotrophic or heterotrophic - extremely diversified groups - certain types may be ancestors of mitochondria
What is the opposite of a prokaryotes cell?
Eukaryotic cells are cells that contain nuclei and have complex structures. Prokaryotes are generally unicellular and lack nuclei.
How do prokaryotes differ from the other kingdoms?
bacteria does not have a nucleus

Does archaebacteria contain peptidoglycan?
no
Gram-positive bacteria have a thick cell wall composed of?
Gram positive bacteria are so called because their cell walls are one thick layer of peptidoglycan, basically, so the stain is trapped in the cell wall and not rinsed away.
Which of the following are one-celled organisms with no nucleus?
Cells without nucleus are called Prokaryotic cells. In addition, they contain no membrain bounded organells, they are smaller in size, they contain peptidoglycan, no vacuoles, and reproduction is assexual (binary fission or conjugation)
Which kingdom has organisms with peptidoglycan?
The Domain Bacteria and Kingdom Eubacteria contain organisms with peptidoglycan in their cell walls.
Do prokaryotic cell walls contain peptidoglycan?
prokaryotes are bacterial cells. Bacterial cells can be either gram positive or gram negative. If the cell wall is gram positive it will have a cell membrane covered by MULTIPLE layers of peptidoglycan with strings of techolic acid going thru it. If the cell wall is gram negative it will have a cell membrane covered by ONE layer of peptidoglycan and an outer membrane surrounding it.
What polysaccharides makes up the plat cell walls?
Plant cell walls are mostly composed of cellulose. They also contain hemicellulose and pectin. Bacterial cell walls are made of peptidoglycan.
A kind of cell that has no nucleus?
Prokaryotes are (mostly) unicellular organisms without an nucleus.Humans on the other hand are multicellular eukaryotes. Our cells contain nuclei EXCEPT for red blood cells. These do not contain a nucleus in order to be able to transport more oxygen.
Does bactieria have a nuclues?
No, bacterium do not have a nucleus. They are unicellular organisms that have their genetic material in the cytoplasm. They are classified as "prokaryotes" which literally translates to mean "pre-nucleus".
