• C. (a), (c), (d)
• D. (a), (c), (d), (e)

Answer 1

The correct option is C (a), (c), (d)

• Anther lobes are attached to each other by a longitudinal groove which is a band of vascular sterile tissue that runs lengthwise.
• Cellulosic fibrous bands are not found in members of the hydrophytes. Fibrous bands are required during the time of dehiscence of anthers. As in hydrophytes, the hygroscopic nature of endothecium helps in the dehiscence process so fibrous bands are not required.
• Microsporangium contains sporogenous tissues, which are meristematic and differentiate to form the microspore mother cell. The microspore mother cell undergoes meiosis to form microspores of pollen grains.
• Cells of tapetum nourish the developing pollen grains.
