A. Conical B. Umbrella
C. Spherical D. Columnar
E. All of the above

A. Palm trees B. Bamboo
C. Conifers D. All of the above

4.  General characteristics of crown are:
A. In young age crowns are usually conical in shape but as the time passes the crown shape becomes rounded B. Drooping forms also occur in many species e.g. Polyalthia longifolia
C. Both (a) & (b) D. None of these

5.  Variation in 'Stem shape' is:
A. in Most conifers, many species of bole dipterocarpus, Eucalyptus, Populus and Salmalia malabarica etc. B. In Teak seedlings have no branches till their third growing season
C. Both (a) & (b) D. None of these

6.  Forked Stem' is:
A. Sometimes two shoots appear at the same time, giving usually a larger crown but from the forester's point of view, this is a most unsatisfactory bole B.
