Apr 1, 2024 · Cell can be eukaryotes (membrane bound organelles and specialized structures) and prokaryotes (few simple structure). Both these cells can divide -replicate, grow and respond to environment. Endosymbiotic theory states that some of the organelles in the eukaryotic cells were once prokaryotic cells.
Mar 22, 2024 · The cell theory states that cells are the smallest unit of life and that organisms are made of cells. Both skeletal muscle cells and fungal hyphae are made from elongated cytoplasm with more than one nucleus. These structures are a problem for cell theory because they are not strictly made of cells.

The cell culture may be divided into three according to their history: 1) primary, 2) secondary and 3) continuous cell culture. The primary and secondary cells are usually diploid cells. Primary cell lines derived directly from an intact tissue like animal’s embryo or kidney.
