What else can I help you with?
What are three domaines into which organisms are classified?
The answer is eubacteria, archaebacteria, and eukaryotes
What kingdoms contain organisms that are eukaryotes?
Every kingdom, except archaebacteria and eubacteria, are eukaryotic.
Do eukaryotes include the kingdom eubacteria and archaebacteria?
No, eukaryotes are a separate domain of life that includes organisms with membrane-bound organelles. The kingdoms Eubacteria and Archaebacteria belong to the domain Bacteria, which consists of prokaryotic cells lacking membrane-bound organelles.
Why are eukaryotes more closely related to archaebacteria than eubacteria?
Eukaryotes are believed to have evolved from a symbiotic relationship between an ancient archaebacterium and a eubacterium. This theory is supported by similarities in their genetic sequences, membrane structure, and other cellular processes. As a result, eukaryotes share more genetic and structural similarities with archaebacteria than eubacteria.
Where chromosomes are in a cell?
Chromosomes are found in the nucleus of animal cells (eukaryotes). In bacteria and archaebacteria, they float freely in the organism.
Are archaebacteria prokaryotes?
Yes, archaebacteria are prokaryotes, which means they have a simple cell structure without a nucleus or membrane-bound organelles. They are one of the three domains of life, along with bacteria and eukaryotes.
What kingdom does not have nucleus in its cells?
The thing is Eukaryotes don't have a nucleus, but prokaryotes do. So if Archaebacteria and Eubacteria are prokaryotes, and Protists, Fungi, Plants and Animals are Eukaryotes, than that means Archaebacteria and Eubacteria have a nucleus and Protists, Fungi, Plants and Animals don't have a nucleus.
Is a mushroom an archaebacteria?
No, a mushroom is part of a much larger organism a fungus. Fungi are eukaryotes (large cell containing organelles) while archaebacteria are prokaryotes (small single cell without organelles).
What type of cell is Archaebacteria?
Archaebacteria, now known as Archaea, are a type of single-celled microorganism that can thrive in extreme environments. They have unique molecular characteristics that differentiate them from both bacteria and eukaryotes.
Which group of prokaryotes do scientists think may be ancestors of eukaryotes?
Scientists think that archaea may be the group of prokaryotes that are most closely related to the ancestors of eukaryotes. This is based on genetic and biochemical similarities between archaea and eukaryotes, as well as the shared presence of certain cellular structures and processes.
What is special about archaebacteria?
Archaebacteria are a unique group of prokaryotic microorganisms that thrive in extreme environments like hot springs, salt flats, and deep-sea hydrothermal vents. They have distinct cell membrane compositions and genetic sequences separate from both bacteria and eukaryotes. Some archaebacteria play vital roles in biogeochemical cycles and have potential applications in biotechnology and medicine.
What is the difference between archaebacteria and cyanobacteria?
Archaebacteria are ancient prokaryotic organisms that can survive in extreme environments, while cyanobacteria are photosynthetic prokaryotes that produce oxygen as a byproduct of photosynthesis. Archaebacteria are more closely related to eukaryotes, while cyanobacteria are responsible for the oxygenation of Earth's early atmosphere.
