Pine trees will always have needle shaped leaves, they stay like this forever. The "needle shaped leaves" are called pine needles. Most pine trees belong to a group of trees called Evergreens. Like it's name, the tree is evergreen.

These are called deciduous trees. Trees that keep their leaves in winter are called coniferous. Most coniferous trees have needle leaves and cones. Deciduous leaves vary in shape and size but most trees that don't have a needle shaped leaf are deciduous trees.


no. Coniferous trees have needle-shaped leaves that stay on in the winter and they produce brown cones that hold its seeds. Oak leaves fall off in the fall, are not shaped like needle and the tree does not produce brown cones.


Trees must survive the winter in order to grow back during spring time. Trees adapt themselves in many ways to survive during winter.Deciduous treesDeciduous trees shed their leaves during winter time. This helps to prevent water loss through the stomata present on the leaves.Trees absorb all the nutrients from the leaves and then forms a layer that cuts off the leaves from the twig. This way the tree has more nutrients to make it through the winter and grow again during spring time.Coniferous treesConiferous trees retain their leaves through the winter. Their leaves are needle shaped to reduce the surface area through which water can escape.The water in the leaves are pushed out and this water freezes to form ice. This protects the inner layer of cells from damage.The leaves have a waxy coating that protects the inner layer of cells. The needle shaped leaves do not accumulate snow and protects the tree from breaking due to the weight of the snow.The conifer trees are cone shaped that helps the snow to easily glide off the tree.


The shape of the tree helps the tree to shed snow. The leaves are needle-shaped and waxy so that they do not lose water from winter drying. The leaves are evergreen so that they can carry on photosynthesis whenever possible during the year... Even when the trees are on fire


American beach trees do not usually lose all of their leaves. Their leaves are teardrop shaped.


No evergreen tree loses all it's leaves in Winter although some conifers such as the Larch do. All conifers are not evergreens but all evergreens keep their leaves in Winter.


The trees that have needles instead of flat leaves, have them because Needles reduce evaporation so trees can save water. especially during the winter. The narrow leaves have a thicker skin, a thicker coating of waterproof wax and a needle-like shape reducing the leaf area and the amount of water vapor escaping the leaf.


Deciduous trees lose their leaves in WinterDeciduous trees lose there leaves in the Autum, most are gone by winter, they grow back during the Spring.deciduousPlants that shed their leaves shortly before winter to conserve energy are called deciduous.Trees that lose their leaves in the Winter are called Deciduous Trees.Deciduous trees are trees that lose their leaves in Winter.Evergreen, or coniferous.- these do NOT loose their leaves (needles) in the winter. Deciduous trees like maple, oak and hickory loose their leaves in the winter,


Yes! But not during the winter. They continually loose there leaves in a cycle.


Leaves fall of trees during winter because it reduced sunlight it keeps them from producing much energy. As a result, trees shed their leaves during the winter to save energy. Leaves gradually lose their color and then fall off as weather gets colder and days become shorter.



do ferns lose their leaves in winter. Although ferns are evergreen plants, their leaves perish in the snow in the winters and fresh leaves emerge during spring and autumn seasons.


During Winter, after they have lost their leaves during Autumn.


Less leaves in winter is energetically favorable for any tree. Less availability of sunlight during the winter is one of the main cause to shed leaves. Trees can use their stored up energy for long time if they have less leaves, to get by harsh winter.


The tree is virtually hibernating and drops its leaves so that it may avoid freezing of free water in the leaves during winter season.


Because some of the nutrients of the leaves are pulled back into the plant.


No. Hemlocks(Tsuga) are evergreens,so they do not lose their foliage in winter.


It helps prevent water loss to coniferous trees in the winter in coniferous forests


Most salamanders hibernate during winter inside rotting or decaying logs, under leaves, or underground.


Evergreen trees keep their leaves/needles over the winter months. Deciduous trees lose their leaves during the winter months.


Hi. I have a pomegranate tree at home. I have had it for about two years. It has never lost its leaves during the winter. Hopes this helps you :-)


The main feature of conifers are (as the name suggests) cones. Conifers (literally cone bearers) lack the gaudy flowers and bright leaves typical of angiosperms, replacing them with the familiar cones and needle-like leaves we see on pine and spruce trees. They typically keet their leaves during the winter.


Evergreen tress have characteristics that give them their name- they have green needle like 'leaves; and they do not typically lose their leaves in winter like other trees do.


Bluebells are deciduous plants that only need their leaves to produce food during the summer when there is more sunlight


Generally, hardwoods are deciduous trees -that is, they have broad, thin leaves that they drop for winter. Softwoods are coniferous -that is, they have needles or needle-like leaves that they DO NOT drop for winter, causing many to also be referred to as evergreens.
