Detailed Solution

Step 1: Understand the structure of an angiosperm anther

A typical angiosperm anther is described as bilobed. This means it consists of two distinct lobes connected by a connective tissue.

Step 2: Analyze the internal structure of each lobe

Each lobe of the anther contains two theca (singular: theca). Therefore, the anther is often referred to as dithecous.

Step 3: Calculate the total

Since each lobe contains 2 theca, and there are 2 lobes in a bilobed anther, the total number of theca in the entire anther is 4 (tetrasporangiate). However, the question specifically asks for the number of theca in each lobe.

Final Answer: 2
