Solution
The correct statement from the following with respect to anther is D
A typical anther is tetragonal and tetrasporangiate.
An anther is not always bilobed and dithecous.
Some flowers may have monothecous anthers which have a single lobe/theca or polythecous anthers containing many lobes.
A typical anther as seen in a transverse section is tetragonal and bilobed with each lobe containing two microsporangia. Therefore, it is tetrasporangiate.
The two lobes of an anther is seen distinctive in its transverse section.
