With the help of a labelled diagram describe the structure of mature anther in cross section

Anther:

• A typical anther is bilobed and each lobe is dithecous (consists of two theca).

• Theca are separated by a longitudinal groove running lengthwise.

• The microsporangia are located at the corners, two in each theca. They further develop to form pollen sacs, which contain the pollen grains.
