The archesporium is a group of cells that gives rise to the sporogenous tissue within the anther of a flowering plant. The sporogenous tissue is responsible for producing the pollen grains, which contain the male gametes of the plant.
The archesporium is located in the center of the anther, and it undergoes repeated rounds of cell division to produce a mass of cells known as the sporogenous tissue. This tissue is surrounded by a layer of cells known as the tapetum, which provides nutrients and support to the developing pollen grains.
The wall of the sporangium, which encloses the sporogenous tissue and tapetum, is also produced by the archesporium. This wall becomes the outer layer of the anther, protecting the developing pollen grains until they are ready to be released.
Therefore, the correct answer is option C - the archesporium gives rise to both the wall of the sporangium and the sporogenous cells that produce the pollen grains.

The archesporium is a group of cells in a flowering plant that gives rise to the sporogenous tissue, which eventually forms the spores. The tapetum is a layer of cells that surrounds the developing spores and provides them with nutrients.
Explanation:
The archesporium is a group of cells that is located in the anther or ovule of a flowering plant. This group of cells gives rise to the sporogenous tissue, which eventually forms the spores. The sporogenous tissue is located within the anther or ovule and is responsible for producing the spores that will give rise to the gametophyte generation.
The tapetum is a layer of cells that surrounds the developing spores and provides them with nutrients. The tapetum is also derived from the archesporium, but it does not give rise to the spores themselves. Instead, it provides the developing spores with nutrients and other essential materials.
In summary, the archesporium gives rise to both the wall of the sporangium and the sporogenous cells, which eventually form the spores. The tapetum is also derived from the archesporium, but it does not give rise to the spores themselves. Instead, it provides the developing spores with nutrients and other essential materials. Therefore, option C is the correct answer.
