1 tapetum lies between endothecium and middle layers
2 tapetum lies just inner to endothecium
3 middle layer is the between endo thecium and tapetum
4 endothecium lies to middle layer
Explanation:
Anther wall include single layer of epidermis, a single layer of endothecium, one to three middle layers and a single layer of tapetum. Epidermis is outermost layer and it is protective in nature. Middle layer is present between the endothecium and tapetum and it generally disintegrate when anther nature. Tapetum is innermost layer and nutritive in nature.

Which part of the plant contains sporogenous tissue?
1 Pollen
2 Microspores
3 Young anther
4 Stamen
Explanation:
Young anther of the plant contains sporogenous tissue. These are located in the centres of each pollen sac of young anther. Pollen is a powdery substance consisting of pollen grains. Microspores are formed from microspore mother cells inside the anther. Stamen is the male reproductive part of a flower. It consist of anther and filament.

Developing pollen is nourished by
1 tapetum
2 endothecium
3 epidermis
4 middle layer
Explanation:
Each pollen sac is consist of four layer of the cells i.e., tapetum endothecium, middle layer and epidermis. Epidermis is protective in function and it is outermost covering. Tapetum is innermost layer of the pollen sac and it provide nutrition to the developing pollen grains. It is also referred to as a source of precursors for the pollen grain coat.

Number of androcytes required to form 32 male gametes in the plant with dicyclic dictyostele belonging to Polypodiaceae is:
1 4
2 8
3 10
4 32
Explanation:
Number of androcytes required to form 32 male gametes in the plant with dicyclic dictyostele belonging to polypodiaceae is 32 . Because polypodiaceae is a family of loss pteridophytes. In pteridophytes male gametes are formed from androcyte cells. In this process one male gamete is formed from one androcyte. So, 32 gametes will be formed from 32 androcytes.
