Find incorrect statements related to water relations in plants:
A. Water potential difference is the drawing force for osmosis.
B. The driving force of diffusion is the concentration gradient.
C. Pressure potential is negative.
Analyzing each statement.
Statement A is correct as osmosis is driven by a difference in water potential.
Statement B is also correct; diffusion indeed occurs due to a concentration gradient.
Statement C is generally incorrect as pressure potential in plant cells is typically positive due to turgor pressure, though it can become negative under severe water stress.
Match the plant growth hormones of Column-I with suitable chemical derivatives present Column-II and choose the correct option given below:
The table below lists potential environmental conditions in future climates, related to atmospheric carbon dioxide concentrations (CO2) and mean annual temperature (MAT). The table also lists potential outcomes with respect to whether conditions will favour grasses with C3 or C4 photosynthetic pathways. Assuming no other changes in environmental conditions, match the options in the two columns.
