Question

A typical angiosperm anther is _________ and _________. *

1 point

(1) Bilobed, tetrasporangiate

(2) Bilobed, monosporangiate

(3) Bilobed, bisporangiate

(4) Tetralobed, monosporangiate​

Answer 1

Answer:

The male reproductive organ of plants is Stamen which has two parts: the long and slender stalk called the filament and a terminal generally bilobed structure called the anther. The anther is four sided i.e. it has four locules consisting of four microsporangia located in each locule which develops further and become the pollen sacs.

Thus, an anther is tetrasporangiate because it has four microsporangia.

Answer 2

Answer:

A typical angiosperm anther is bilobed with each lobe having two theca, thus they are called dithecous. Microsporangium is nearly circular in outline. It is surrounded by four wall layers that is the epidermis, endothecium, middle layers and the tapetum.
