• B. Anther lobe with one theca is called dithecous.
  
  
• C. The bilobed nature of anther is distinct in its longitudinal section.
  
  
• D. A typical anther is tetragonal and tetrasporangiate.

Answer 1

Answer: (C), (D)

The correct options are
C

The bilobed nature of anther is distinct in its longitudinal section.

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 clearly in a longitudinal section of an anther.
