6.) the process by which large molecules are expelled from a cell

A cell uses a process called exocytosis to expel large molecules. The process is shown on the right. Note how the contents are packaged in a membrane bound vesicle which fuses with the cell membrane to expel its contents.

one is through turgidity. this occurs before ground tissue ( collenchyma

and sclerenchyma cells) become well

developed to give structural support to the plant as it grows bigger. the xylem

tissue (composed of rigid tissue) of the young

plant render this support and also maintaining osmotic turgidity of the surrounding

plant cells.
