The tapetum is the innermost layer of the anther wall that provides nourishment to the developing pollen grains. It plays a crucial role in the formation of pollen wall materials such as sporopollenin and also aids in the production of enzymes and proteins required for pollen development.
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.
(b) Order of the differential equation: $ 5x^3 \frac{d^3y}{dx^3} - 3\left(\frac{dy}{dx}\right)^2 + \left(\frac{d^2y}{dx^2}\right)^4 + y = 0 $
