Identify the correct option with respect to the angiosperm anther:

The correct answer is Option (3) → It is bilobed and dithecus

A typical angiosperm anther is bilobed with each lobe having two theca, i.e., they are dithecous  . Often a longitudinal groove runs lengthwise separating the theca. Let us understand the various types of tissues and their organisation in the transverse section of an anther . The bilobed nature of an anther is very distinct in the transverse section of the anther. The anther is a four-sided (tetragonal) structure consisting of four microsporangia located at the corners, two in each lobe. The microsporangia develop further and become pollen sacs.
