⚙️ Eukaryotic and prokaryotic cell structure and function

I once rescued my biology grade back in secondary school in Romania by knowing the definition of a cell.

“The cell is the structural and functional unit of living things” I wrote. I wasn’t far off was I? So yes, the cell is the unit of life. It’s a delimited volume where the chemistry of life can happen. In unicellular organisms, the cell is themselves, the body, the whole, the organism.



In complex, multicellular organisms cells organise themselves in such a way that enables a greater structure and function. Cells differentiate into specific structures and functions, and organise themselves as such into tissues. The different tissues can then form organs with yet a higher level of structure and function, and organs can work together in certain broad areas of the organism’s structure and function by taking part in…
