Which organelles most likely appeared last in eukaryotic cells?
The nucleus is thought to have appeared last in eukaryotic cells. This is supported by the endosymbiotic theory, which suggests that eukaryotic cells evolved from prokaryotic cells through a series of symbiotic relationships.
When did the first cells appear on earth?
The first cells appeared on Earth approximately 3.5 billion years ago during the Archean Eon. These cells are believed to be simple, single-celled prokaryotes.
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.
What do cells come from?
For the past 3+ billion years, cells only come from the reproduction of previous cells. Originally, the first simple bacterial cell appeared through a process called abiogenesis, but the conditions necessary for that to happen are long gone now.
When did the first Archaebacteria appear?
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
How was colored photography important?
The most important aspect of colored photography was the cure for the Polio virus. In order for scientists to distinguish the difference between cells in a sample, they needed to use high resolution photographs. When the photos were taken, all the cells appeared in black & white, so scientists could not distinguish between the gamma cells and the beta cells. Gama cells are dark red in color and beta cells are dark blue. When the first color camera was used to document these microscopic cells, Dr. Francis Wellington was able to extract the gamma cells to use in creation of the vaccine.
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.
How do cells of the onion specimen appear under the microscope?
Cells of an onion specimen appear rectangular or square in shape, with distinct cell walls forming the outer boundary. These cells also contain a large central vacuole that may appear as a clear, empty space in the center of the cell under the microscope. The cells are tightly packed together in a regular pattern, creating a characteristic appearance when viewed at high magnification.
