Such trees are Deciduous.
Trees that do not drop their leaves in the autumn are called evergreens. Cone bearing trees are called conifers. All conifers are not evergreen and all evergreens are not conifers.
The name is given because they drop their leaves in the Autumn and regrow them in the Spring.
Yes every tree has leaves except a few xerophytic plants like Australian acacias
As with all other trees foliage covers it.
Many dormant objects do, but it is not a requirement.
They are not deciduous trees so they don't have a dormant stage. The best time to plant them is in Spring time when all chance of late frosts are over.
All pear trees are called Pyrus followed by the species or Cultivar name.
All deciduous trees lose their leaves in winter.
Not always. While some occupational names directly relate to the person's occupation, others have evolved over time and may not accurately reflect the individual's work. These names could also indicate an ancestor's association with a particular trade or profession, regardless of their own occupation.
Most trees are green, but some dead trees are brown. In the fall, they are orange. :)
Evergreen.
