Turgid cell dropped into sucrose solution , the cell has Yp = 0.488 MPa Ys = –0.732 MPa Yw = –0.244 Mpa , 0.3 M Sucrose solution contain Yp = 0 MPa Ys = –0.732 MPa Yw = –0.732 Mpa , Choose the correct option

#Unit 6. System Physiology – Plant
  1. Water particles move out of the cell, Cell membrane Shrinks and detaches from the cell wall
  2. Water particles move into the cell, cell wall counteracts osmotic pressure  to prevent swelling and lysis
  3. No net movement of water particles , Cell membrane is attached to cell wall
  4. A solution that has the same solute concentration as another solution

Multiple factors regulate flowering in Arabidopsis. FT mRNA is expressed in companion cells of the leaf vein in response to multiple signals, including day length, light quality, and temperature. FT moves in the phloem from leaves to the apical meristem. FT is unloaded from the phloem in the meristem and interacts with FD.

FT-FD complex activates multiple genes. Which of the following combination is correct?(SS)
