13.7.1. Types of Trees:

There are two main types of trees: deciduous and evergreen.

(i) Deciduous trees

♤ lose all their leaves for part of the year.

♤ In cold climates, this happens during the autumn so that the trees are bare throughout the winter.

♤ In hot and dry climates, deciduous trees usually lose their leaves during the dry season.

(ii) Evergreen trees

♤ don’t lose all their leaves at the any time (they always have some foliage).

♤ They do lose their old leaves a little at a time with new ones growing in to replace the old. An evergreen tree is never completely without leaves.
