Abstract: A tissue culture device includes a container having one or more upstanding walls extending upwardly from a floor. The floor of the container has a media having nutrients or growth substances therein. A plurality of plant tissues are within the container compartment and are placed upon a screen between the plant tissues and the media. The screen is tamped downwardly onto the media so that the plant tissues can get nutrients from the media, and so that waste products are transferred into the media. The screen is also removable through the open end of the container so as to remove all of the plurality of the plant tissues from the container at once. The plant tissue device can then be placed in another container having any cultured media as needed for the correct maintenance, propagation and development of plant tissue in culture.
