Which Type Of Cell Came First In Evolution The Eukaryotic Cell Or The Prokaryotic Cell
Answers
Answer:
Prokaryotic cell....... In bacterias
Answer:
PROKARYOTIC CELL.
Explanation:
The first cells were most likely primitive prokaryotic-like cells, even more simplistic than these E. coli bacteria. The first cells were probably no more than organic compounds, such as a simplistic RNA, surrounded by a membrane.
Prokaryotes were the first forms of life on Earth, and they existed for billions of years before plants and animals appeared. The Earth and its moon are thought to be about 4.54 billion years old.
A generation ago, scientists believed that membranous droplets formed spontaneously. These membranous droplets, called protocells, were presumed to be the first cells. Modern scientists believe, however, that protocells do not carry any genetic information and lack the internal organization of cells.
The first cells consisted of little more than an organic molecule such as RNA inside a lipid membrane. One cell (or group of cells), called the last universal common ancestor (LUCA), gave rise to all subsequent life on Earth. Photosynthesis evolved by 3 billion years ago and released oxygen into the atmosphere.
