Functions of Tapetum
1. What is the Function of Sporopollenin?
Sporopollenin is a highly resistant biopolymer that forms the outer layer, known as exine, of spores and pollen grains in plants. The primary function of sporopollenin is to provide structural support and protection to spores and pollen grains.
2. Are there different Types of Tapetum?
Yes, tapetum based on developmental characteristics and functions can be categorized into various types, such as secretory tapetum, glandular tapetum, amitotic tapetum, plasmodial tapetum, and binucleate tapetum.
3. Why is the Tapetum essential for Reproductive success in Plants?
The tapetum plays a fundamental role in the proper development, nourishment, and maturation of pollen grains. These three processes are essential for the reproductive success of flowering plants.
4. What happens to Tapetum cells after supporting Pollen development?
After pollen development, tapetum cells undergo programmed cell death (apoptosis), secreting enzymes that facilitate the maturation and release of mature pollen grains from the anther.
5. What happens if the Tapetum does not function properly?
If the tapetum does not function properly, it can lead to male sterility in plants, affecting pollen development, fertilization, and seed production, thereby impacting crop yields.
Tapetum – Types and Functions
The functions of tapetum entail the supply of nutrition and enzymes essential for the process of microsporogenesis and the successive development of pollen grains. This article discusses how the tapetum contributes significantly to the reproductive success of flowering plants, its types, and the functions it performs.
