What else can I help you with?
Is the following true or false The ancestor of all eukaryotic cells evolved about 2 billion years ago?
True. The ancestor of all eukaryotic cells is thought to have evolved approximately 2 billion years ago through a process of endosymbiosis, where prokaryotic cells engulfed other prokaryotic cells, leading to the formation of more complex eukaryotic cells.
What is cellular organization?
It basically means all cells are divided into two types: prokaryotic cells and eukaryotic cells. Prokaryotic cells evolved 3.5 billion years ago and have a nucleus. Examples of a Prokaryotic cell include protista, fungi, plants and animals. Eukaryotic cells evolved 1.5 billion years ago and do not have a nucleus. An example of a Eukaryotic cell is bacteria.
Is the evolution of the prokaryote before a eukaryote cell?
Yes, prokaryotic cells evolved before eukaryotic cells. Prokaryotic cells lack a nucleus and membrane-bound organelles, while eukaryotic cells have both. It is believed that eukaryotic cells evolved from prokaryotic cells through a process called endosymbiosis.
What evolved from prokaryotes?
Eukaryotic cells evolved from prokaryotes.
How long the prokaryotes populated Earth before the evolution of eukaryotic cells which are more complex?
Prokaryotes populated Earth for about 1.5 billion years before the evolution of eukaryotic cells, which are more complex. Eukaryotic cells are believed to have evolved around 2 billion years ago through a process called endosymbiosis.
Which organelle indicates that eukaryotic cells have evolved from prokaryotic cells?
Mitochondria, which are thought to have originated from a symbiotic relationship between early eukaryotic cells and aerobic bacteria, provide evidence that eukaryotic cells have evolved from prokaryotic cells. Mitochondria have their own DNA and ribosomes, similar to prokaryotic cells, and carry out cellular respiration, a process that is also similar to bacterial metabolism.
What cell do scientists think evolved about 1.5 billion years ago?
Scientists believe that eukaryotic cells, containing membrane-bound organelles and a nucleus, evolved about 1.5 billion years ago through a process known as endosymbiosis. This event led to the formation of more complex organisms and paved the way for the diversity of life we see today.
Are chloroplasts found in plant cells why?
This is an accident of how the first eukaryotic plant cells evolved to be different from other eukaryotic cells billions of years ago. It is what defines eukaryotic plants.
Are prokaryotic cells older than eukaryotic cells?
Yes, prokaryotic cells are generally considered to be older than eukaryotic cells in terms of evolutionary history. Fossil evidence and molecular studies suggest that prokaryotes appeared on Earth around 3.5 billion years ago, while eukaryotes evolved much later, around 1.6 billion years ago.
Why are the chloroplasts found in plant cells only?
This is an accident of how the first eukaryotic plant cells evolved to be different from other eukaryotic cells billions of years ago. It is what defines eukaryotic plants.
How old are eukaryotic cells?
Eukaryotic cells are believed to have originated around 1.6-2.1 billion years ago. They are much younger compared to prokaryotic cells, which are estimated to have appeared around 3.5 billion years ago.
Why are prokaryotes older then eukaryotes?
Prokaryotes are considered older because they appeared in the fossil record earlier than eukaryotes. It is believed that the simpler structure of prokaryotic cells made them better suited for survival in the early Earth conditions. Eukaryotic cells with their complex internal structures evolved later.
