The microsporangia develop further and become:

Read the following statements and find out the incorrect statement. a. The number and length of stamens is variable in flowers of same species. b. A typical angiosperm anther is bilobed with each lobe having two theca. c. Often a longitudinal groove runs lengthwise separating the theca. d. The anther consists of four microsporangia located at the comers one in each lobe. e. The microsporangia develop further and become pollen sacs. They extend longitudinally all through the length of an anther and are packed with pollen grains.

Read the following statements carefully and select the appropriate option given below. (i) The distal end of the filament is attached to the thalamus or the petal of the flower. (ii) The pollen grains represent the male sporophyte. (iii) The microsporangia develop further and become embryo sac. (iv) In over 60 per cent of naked seeded plant, pollen grains are shed at this 2-celled stage. (v) As anthers mature and dehydrate the microspores, dissociate from each other and develop into pollen grains.

Number of microsporangia in a dithecous anther is:

Number of microsporangia in a dithecous anther is:

Assertion: In gymnosperms development of male gametophyte (pollen grain) takes place within the microsporangia. Reason: Gymnosperms are heterosporous plants in which spores show in situ germination.
