The transport of gases,hormones,photosynthates,and organic solutes in plants is:

Differentiate between apoplast and symplast pathways of water movement. Which of these would need active transport?

Osmosis involves

Choose the correct option:
$(1)$ The transport in xylem is always $unidirectional$.
$(2)$ The process of loss of water in the form of vapour by plants is called $transpiration$.

Study the following statements and choose the correct option$(s)$ from the codes below:
$I$. Root pressure provides a light push in the overall process of water transport.
$II$. Root pressure causes the flow of water faster through xylem than it can be lost by transpiration.
$III$. In symplast pathway,water moves exclusively through the cell wall and intercellular spaces.
$IV$. Guttation is a cause of transpiration pull.
$V$. Most plants fulfill their water requirement by transpiration pull.

Give differences between:
$(1)$ Osmotic Pressure and Osmotic Potential
$(2)$ Diffusion and Imbibition
