Roots.
Most have needles through year
No, pine trees do not have leaves. They have pine needles that have a waxy coat on them. People refer to them as pine leaves sometimes, but that isn't what they are.
in the the Mediterranean dry or no tropical plants grow in the Mediterranean like chaparral, or shrubs and short trees. Most plants that live in the Mediterranean climate have thick barks, long roots to reach the water and small thin leaves (needles) to reduce moisture loss. Most plants flower in the winter for that is when most of the precipitation happens.
Pine trees themselves can be identified because they are the only trees that have bundled needles: groups of needles wrapped firmly together at one end. Most olny have up to seven needles in a bundle!
they normally keep their leaves all year long due to the constant fertilization and moisture in the tree roots and the leaves
Trees are provided with numerous leaves and during day time when stomata are open, a lot of water vapours come out by transpiration adding to the moisture in the air. Thus, humidity in the air is largely affected by the density of trees in that area.
Evergreen refers to trees that normally retain most of their foliage (needles) through the winter. Trees that do shed their leaves are known as deciduous.
the roots would grow toward the trees to get its food and water
They are called evergreens , most of them are conifers.
There are a variety of types of trees that absorb a lot of water. One of the most popular trees is the weeping willow.
Buttress roots, also called stilt roots or prop root, are large roots on all sides of a shallowly rooted tree that prevent the tree from falling over. They are usually found in nutrient-poor rainforest soils and do not penetrate to deeper layers. Most mangroves trees have these type of roots.
All trees grow up by and from the roots.Specifically, it is by the roots that trees, shrubs and herbaceous plants take in necessary nutrients. Not all plants have to be anchored in soil. Epiphytic orchids whose roots dangle from tree branches high up in the air may be offered as examples of herbaceous plants that can live without soil. But all trees must have roots growing in soil to survive.
