Mark the given statements True (T) or False (F).

(i) Androecium consists of a whorl of stamens representing the male reproductive organ and the gynoecium represents the female reproductive organ.

(ii) The two parts of a typical stamen are the long and slender stalk called filament, and the terminal generally monolobed structure called the anther.

(iii) The distal end of the filament of stamen is attached to the thalamus or the petal of the flower.

(iv) The bilobed anther consist of four microsporangia located at the corners. They develop further and become pollen sacs.

(v) In microsporangium, cells of the tapetum possess loose cytoplasm and generally have more than one nucleus.

(vi) When anther is young, a group of compactly arranged homogenous cells called sporogenous tissue occupies the center of each microsporangium.

(vii) The process of formation of microspores from a pollen mother cell through meiosis is called macrosporogenesis.

(viii) The pollen grains represent the male gametophytes.

(ix) The hard outer layer of pollen grain called exine is made up of pectin.

(x) Pollen grain exine has prominent apertures called germ pores where sporopollenin is absent. Pollen grains are well-preserved as fossils because of presence of sporopollenin.

(xi) The inner wall of the pollen grains is called intine. It is a thin and continuous layer made up of cellulose and pectin.

(xii) When the pollen grain is mature it contains two cells, the vegetative cell and generative cell.
