9.2- water in multicellular plants

what is the symplast pathway?

Water enters the cytoplasm through plasma membrane, it then passes through plasmodesmata from cell to the next. Once in the cytoplasm water can move from cell to cell by osmosis

What is the apoplast pathway?

Water passes through cell wall until it reaches the casparian strip

What happens, when it the apoplast pathway, the water reachers the casparian strip?

The apoplast pathway stops and water joins the symplast pathway

What is root pressure?

root pressure pushes water up the xylem. This is done where the action of the endomermis move minerals into the xylem by active transport which drives water into the xylem by osmosis thus pushing it upward (once in the xylem water moves by mass flow)

What is the endodermis?

The endodermis is a layer of cells found in the root of a plant, surrounding the vascular tissue
