Science has observed that cells are the basic structural and functional units of life. Through various experiments, scientists have determined that cells have distinct structures and functions, and that they are capable of performing all the necessary processes for life, such as growth, reproduction, and metabolism. Overall, the conclusions drawn from these observations have revolutionized our understanding of Biology and medicine.
which observation proves that cells is eurkaryote
The presence of a nucleus surrounded by a membrane is a key observation that proves a cell is a eukaryote. Eukaryotic cells also typically have membrane-bound organelles, such as mitochondria and endoplasmic reticulum, which are not found in prokaryotic cells. Additionally, eukaryotic cells are generally larger and more complex in structure compared to prokaryotic cells.
An in vitro observation should be confirmed in vivo to ensure that the results observed in a laboratory setting using isolated cells or tissues can be replicated in a living organism. This is important to determine the relevance and potential implications of the observation in a complex biological system.
The presence of a membrane-bound nucleus and other organelles, such as mitochondria and endoplasmic reticulum, indicates that a cell is a eukaryote. Eukaryotic cells are typically larger and more complex than prokaryotic cells.
Robert Hooke discovered cells in plant tissue when he observed thin slices of cork under a microscope. His observation of cells marked the beginning of the field of cell biology.

Cells were discovered in 1665 and the observation of cell parts in muscle cells was discovered in 1857. So it would have been roughly 192 years.
One observation of early scientists that supports the cell theory is that all cells divide which was observed in 1855. The other observation was that living things contain cells which was observed in 1839 by Theodor Schwann.
