The prokaryotic cells first appeared about 3 billion years ago. Scientists are not sure but perhaps a few of these bacteria could have been archaea. These appeared in the Pre-Cambrian Era
Archaebacteria arose first, followed by protists, then animals, fungi, and plants. This evolutionary sequence is generally accepted by scientists based on evidence from the fossil record and molecular studies.
they were probably the first multicelluar life- forms
The common name for the Archaebacteria kingdom is archaea.
one kind of archaebacteria is the methanogens
They have their own kingdom called Archaebacteria.
Yes, archaebacteria have a cell wall.
Here are the 3 types of Archaebacteria Archaebacteria>>>>> 1. Methanogens 2. Halophiles 3. Thermoacidiophiles
The archaebacteria are the only anaerobic species, who do not tolerate free oxygen.
The archaebacteria is a unicellular organism without a nucleus. They are known to survive in extreme climates and environments. The first were discovered in 1977 in the boiling hot springs at Yellowstone National Park.
how long has archaebacteria been on earth? how long has archaebacteria been on earth?
Archaebacteria is still present today and not extinct. Archaebacteria is a single cell microorganism and was once classified as bacteria.
a characteristic of archaebacteria are that they live in environments without oxygen
