Question

The first organ to emerge from a germinating seed is the root. You want to see the tissues and cells inside this organ, so you make a L.S. of a seedling root and examine under light microscopy. Label with line on the longitudinal section (L.S.) Where will you see root hairs? Where will you see dividing cells? Where are differentiated water conducting cells? Root cap? The water potential of a root cell in the elongation zone is dependent on _____________ (what two components). If the solute potential of the cell is = -0.8 MPa, and the water potential of the cell is -0.5 MPa. Is this cell able to elongate? Explain why or why not.

Explanation / Answer

Answer:

b). Water moves from a region of high water potential to low water potential region. The maximum water potential is zero.

So water will move into the cell and cell elongate.
