The outer thick layer of microspore is made up of -------------.
The outer thick layer of microspore is made up of -------------.
Options
- Acellulose
- Bpectin
- Csporopollenin
- Dhemicellulose
Correct answer
C. sporopollenin
Step-by-step solution
The microspore (pollen grain) has a two-layered wall. The outer thick layer is called the exine, which is made up of sporopollenin. Sporopollenin is one of the most resistant organic materials known, able to withstand high temperatures, strong acids, and alkalis.
The inner layer is called the intine, which is thin and continuous, and is made up of cellulose and pectin.
