flowers and fruits in rooted plants?

All of the following event involve osmosis except

Choose, true and false statements from the following and select the correct option from the set (a-d) given
below
I. Diffusion is an important process of transport in plants since it is the only means for gaseous movement
within the plant body
II. In active transport, pumps are proteins that use energy to carry substance across the cell membrane
against concentration gradient
III. In facilitated diffusion, special proteins helps hydrophilic substances to be transported across the
membrane
IV. In diffusion, molecules move against concentration gradient in a random manner
V. Facilitated diffusion is faster than active transport
