DENDROLOGY

Detailed explanation-1: -Woody plants are of two types: deciduous and evergreen plants. Deciduous plants tend to go dormant during winter seasons by shedding all their leaves. Evergreen plants do not shed their leaves totally, but keep on shedding in winter seasons until the growth comes to a stop.

Detailed explanation-2: -Hemlock, blue spruce, and white pine are all evergreens. These trees have leaves throughout the year. Oak, maple, and elm are examples of deciduous trees. They lose their foliage in the fall and grow new leaves in the spring.

Detailed explanation-3: -Woody plants may be classified as trees, shrubs or vines and may have evergreen, semi-evergreen or deciduous leaves. Herbaceous plants have stems that die back to the ground each year.

Detailed explanation-4: -Deciduous plants drop their leaves at the end of every growing season, whereas evergreens keep their leaves for up to several years. Herbaceous plants have soft, flexible aerial portions and commonly die back each year.
