The phragmosome is a sheet of cytoplasm forming in highly vacuolated plant cells in preparation for mitosis. [1] In contrast to animal cells, plant cells often contain large central vacuoles occupying up to 90% of the total cell volume and pushing the nucleus against the cell wall. In order for mitosis to occur, the nucleus has to move into the ...

The function and significance of vacuoles varies greatly according to the type of cell in which they are present, having much greater prominence in the cells of plants, fungi and certain protists than those of animals and bacteria. In general, the functions of the vacuole include: Isolating materials that might be harmful or a threat to the cell
Vacuoles of plant cells act as storage compartments for the nutrients and waste of a cell. The solution that these molecules are stored in is called the cell sap. Pigments that color the cell are sometime located in the cell sap. Vacuoles can also increase the size of the cell, which elongates as water is added, and they control the turgor ...
as external source i used another structure found on the book "molecular cell biology" from james darnell, harvey lodish and david baltimore. i tried to convine all in a complete yet simple diagram. i finish it on the 03-feb-05 —LadyofHats 01:12, 3 Feb 2005 (UTC)" Between the changes made are:
Description: The image is a corrected version of an image i made sometime ago. the original quate on the image was "the image describes the parts on a typical plant cell. the image i made myself as resources i used the simple structure here, also the one i found hereand must of the text i could get from here as external source i used another structure found on the book "molecular cell biology ...
The large central vacuole is one of the largest organelles in a plant cell and is generally used for storage. [10] In Chara coralina, cells can grow up to 10 cm long and 1 mm in diameter. [8] The diameter of the vacuole can occupy around 80% of the cell's diameter. [11] Thus for a 1 mm diameter cell, the vacuole can have a diameter of 0.8 mm ...
Light micrograph of a moss's leaf cells at 400X magnification. The following outline is provided as an overview of and topical guide to cell biology: . Cell biology – A branch of biology that includes study of cells regarding their physiological properties, structure, and function; the organelles they contain; interactions with their environment; and their life cycle, division, and death.
