Assertion : An angiospermous flower represents the modified condensed shoot which performs the function of sexual reproduction. Reason : The fertile leaves of the shoot become modified into microsporophylls and megasporophylls which bear ovules and anthers respectively.

Read the following statements and find out the incoorect 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 corners 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.
