Question

Tapetum present in the microsporangial wall occurs between:
A. Epidermis and endothecium
B. Endothecium and middle layers
C. Epidermis and middle layers
D. Middle layers and sporogenous tissue

Answer 1

Hint: A male gamete of a plant species might be referred to as a pollen grain. It has a hard exterior and is a single-celled structure. Due to its lightweight construction, it can move through the air with other dust particles. The pollen grains absorb their nutrition from the tapetum layer which is multinucleated.
Step by step solution:
One of the most crucial layers of a gametophyte that is responsible for providing sustenance to developing microspores is the tapetum (pollen grains). It will be beneficial to discuss the structures of pollen grains and anthers in detail to make the concept crystal apparent.
Structure of Anther:
Two lobes of an anther body are joined together by a sterile connective tissue.
Each of these lobes has two hollow, deep chambers known as microsporangia or pollen sacs. Premature pollen grains, also known as microspores, are stored in these sacs.
Microsporangia have several layers. The epidermis (outside covering of another body) is the outermost layer, followed by the endothecium (a thick fibrous layer concerned with providing a cushion-like platform for developing microspores).
The epidermis, endothecium, middle layer, and tapetum make up microsporangium four wall layers (from outside to inside).
The Tapetum layer descends to the endothecium. The protoplasmic material that makes up this layer provides the growing microspores with food. Additionally, the cells in this structure have several nuclei, which allows them to produce food more quickly and hence give the microspores more nutrients. Thus, it is clear that one of the most significant structures of another body is the tapetum layer.

So, option D is correct.
Additional information:

The microsporangium, which is the location of pollen formation, is a sporogonium structure found in the male reproductive system of the plant. The transverse section has an outline that is circular. The epidermis, endothecium, middle layer, and tapetum make up its four wall layers (from outside to inside). At the endothecium, the cells thicken, and the intermediate layer consists of 2–4 cells. The centre layer, endothecium, and the three outer layers serve to protect the developing anthers and to aid in the anther's dehiscence to release pollen grains. Sporogenous tissue is a collection of tightly packed homogeneous cells that make up the heart of the microsporangium. These tissues then go through meiotic divisions to produce pollen grains in the form of microspore tetrads.

Note: The typical shape of a pollen particle or male gametophyte is a sphere. It has a strong coating all around that makes it completely resistant to bad weather. Its diameter varies between 25 and 50 mm. Anthers dehydrate as they mature, causing microspores to separate and grow into pollen grains.
