Evidence from microfossils strongly suggests that life arose on the earth long ago. Sedimentary rocks 3.5 billion years old (and perhaps those 3.8 billion years old) contain what appear to be microfossils.
Cells dont get old
One day old. Cells die everyday.
Old cells make new cells so that when the old ones die there are new ones to replace them.
The first discovered dead cells are believed to be those of a 3.4 billion-year-old microorganism found in Western Australia in 2013. These ancient cells provide valuable insight into early forms of life on Earth.
First observed cells were plant cells. Robert Hook observed cork cells.
No. Earth itself is "only" about 4.6 billion years old. The first life may have emerged about 4 billion years ago.
Cancer cells are abnormal cells that divide uncontrollably and can invade nearby tissues, whereas old cells are normal cells that have reached the end of their lifespan and stop dividing. Cancer cells can cause tumors and metastasize, while old cells are usually cleared away by the immune system.
viruses dont have cells
Your spleen destroys old red blood cells and stores white blood cells. It is part of your lymphatic system and is found in your abdomen.
lysosomes, organelles found in animal cells but not in plant cells
the answer is no
In the bones.
