The modern cell theory states that living organisms are made of cells, that all cells come from other cells and that cells are the most basic life form. As scientific advancements are made, definitions of theories, like the cell theory, are updated. The modern cell theory is not the same as cell theory of the past.
Cell theory was created upon the discovery of cells, which was done through a primitive microscope by Robert Hooke in the 17th century. Hooke made the discovery while observing plant tissues. As microscopes became more powerful over the years, it became possible not only to identify which type of cells are being observed, but what organelles and other structures are contained in each cell.Learn More
The main function of the cell body of a neuron is to integrate synaptic information and transmit this information to other cells via the axon. The cell body also completes a variety of biochemical processes to keep the neuron functioning properly.Full Answer >
The cell theory scientists were Theodor Schwann and Matthias Jakob Schleiden. Schleiden suggested that all the different parts of plants are made of cells. Schwann came to the same conclusion as Schleiden and stated further that animals were also composed of cells.Full Answer >
The three scientists who formulated cell theory were Theodor Schwann, Matthias Jakob Schleiden and Rudolf Virchow. Schwann and Schleiden worked together to formulate the theory in 1838, and Virchow contributed to the theory in 1858.Full Answer >
Animal cells do not have a cell wall. Instead, animal cells have a cell membrane that protects the organelles inside of the cell and allows selective compounds to move in and out of the cell.Full Answer >
