Deciduous trees generally lose their 'dead leaves' yearly, thru a process called leaf abscission. Ofcourse there are always exception and there are some species of plants that dont abscess their leaves, like many in the plant family Fagaceae which contains the genera of oaks, chestnuts and beech. While its not exactly clear why it happens, I do have some interesting tidbits...
Its been asked alot in botany depts why this happens to this family specifically. Recently, there has been lots of work done showing the actual genes and cellular mechanisms of abscission. And simply put, it seems that Fagaceae doesnt turn those genes on very well but the leaf is definitely unhooked from the rest of the plant... in essence dead weight, just not fallen off.
I could imagine some evolutionary benefits of leaves falling in the spring as opposed to fall. Specifically not letting leaf disease overwinter in the warm soil but the harsh windblown branch. Also spring time leaf mulching.
Dr Evert of UWMadison who is a well known plant anatomist prof did some of the initial work to confirm that infact the leaf of the non abscessed Fagaceae was dead weight to the plant. I believe even to this day, he doesn't have a solid reason on the 'why' but you can research his work if you want the original research papers.
The leaves of a mature beech tree will fall during the Autumn and early Winter. The leaves of a well maintained beech hedge will stay on all Winter. This is either due to the close grouping of the cut hedge or the fact that young, protected shoots can hold on to their dead leaves.
Yes, the Oak tree is deciduous. However there are afew species of Oak that hang onto many of their leaves through all the seasons. These are considered evergreen Oaks because they can stay green all year long. One such Oak is the Live oak from the southern part of the United States.
Deciduous trees lose their leaves in the fall and remain bare during winter, while evergreen trees retain their foliage year-round. Deciduous trees typically shed their leaves as a way to conserve water and energy during colder months, while evergreen trees have needle-like leaves or leaves with a waxy coating that help them retain water and stay green throughout the year.
A deciduous forest is a forest that usually has 4 seasons. The trees loose their leaves in thefall and grow there leaves in the springA deciduous forest is a forest where the trees lose their leaves. There are many types of animals and plants.

Deciduous trees shed their leaves in the fall in response to changes in temperature and daylight. This process, known as leaf abscission, helps the tree conserve water and energy during the cold winter months.
There are several types of trees, including deciduous trees, coniferous trees, and palm trees. Deciduous trees shed their leaves in the fall, while coniferous trees have needle-like or scale-like leaves that stay on year-round. Palm trees have large, fan-shaped leaves. Unfortunately, I am unable to provide pictures of their leaves.
Evergreen trees retain their leaves through the winter.
they don't have leaves, and don't lose their foliage in winter, they stay green.
"Ever greens" are trees that do no shed their leaves in winter and therefore stay ever green.
because at this time their leaves are not required and the wood is used mainly.
Deciduous trees (broad leaf trees) such as English Oak, Beech and Elm.

Needleleaf trees are also known as evergreen trees because they retain their needle-shaped leaves throughout the year, even during winter. This helps them stay green and photosynthetically active all year round, as opposed to deciduous trees that shed their leaves in the fall.
threes that lose their leaves in the winter are called deciduous trees. They lose their leaves to conserve moisture and reduce the amount of energy they must consume in order to stay alive. The leaves of some deciduous trees turn bright colors before they drop to the ground, while others simply fade or turn brown. Environmental factors and the genome of the tree affect how quickly the leaves fall.
You have it backwards. Deciduous trees are the ones that lose their leaves in the winter. They're the ones with the colorful leaves in Fall. Conifers are the ones that stay green all year long. They can do that because they have thin needles instead of leaves, and needles don't freeze as easily as leaves do.
Scientists refer to trees that remain green all winter as "evergreens." These trees retain their foliage throughout the year, unlike deciduous trees that shed their leaves in the fall. Evergreens include species such as pines, spruces, and firs, which have adapted to various climates by developing needle-like leaves that minimize water loss.
A deciduous tree sheds all of its leaves, or in some cases needles, when cold weather prevents the tree from making food.And animals eat the leaves or nedles
