Coniferous trees, other than those that are deciduous such as the baldcypress tree [Taxodium distichum] look green all year long because they drop and regrow their foliage in the course of more than a year instead of the less than a year that's the hallmark of deciduous trees.
because your mom keeps putting leaves on them
They do lose their leaves as the leaves age but not all at once.
The leaf loss is spread thoughout the year so the loss is not noticed.
Because in the winter or the dry season it becomes difficult for the tree to maintain its water balance as there is less free water available in the soil. The lack of water damages the leaves cells. Instead of remaining actively growing during this time of the year the tree enters a dormant period. win
If the leaves on deciduous trees did not fall, the water in the leaves would freeze causing the cells in the leaf to eat themselves from the inside using the lysosomes.
Plants which loose their leaves in the fall/ autumn are called deciduous.
Leaf fall is triggered by a number of factors:
At this point enzymes are released into the plant and stop the production of chlorophyll (the green photosynthetic pigment in leaves and stems). Some species of plants absorb what nutrients are left in the leaves back into the trunk or stem of the plant, in most cases other pigments such Beta-Carotene and Xanthophyll are left behind in the leaves (enhancing the colour effect)
An abscission layer forms between the petiole and the stem, this is basically a layer of callus cells so that the leaf does not leave an open wound when if falls, the abscission layer also facilitates the breaking away of the leaf from the stem.
Leaves fall when the abscission layer breaks - disturbed by the wind or under their own weight.
There are a number of reasons why deciduous plants drop their leaves:
Coniferous trees don't lose their leaves in the fall because it's as a adaptation to low nutrient levels.
Evergreens are covered in a wax like coating and the cells contain a fluid that resists freezing .
No, except for a couple of exceptions the Ginko and the Larch which do drop their leaves in Autumn.
The deciduous trees of temperate forests lose their leaves in the fall. This is a survival tactic for dealing with the long, cold winters often experienced in temperate forests.
They have needles instead of leaves because they can support the heavy weight of the snow better than leaves
Evergreens do not lose their leaves in the winter. Deciduous trees are the name given to those trees that lose their leaves in the winter. There is also a such thing as evergreen deciduous trees which have characteristics of evergreens besides the fact that they DO lose their leaves in the winter.
Evergreen trees keep their leaves/needles over the winter months. Deciduous trees lose their leaves during the winter months.
Yes. They lose their leaves every year, all around the fall. Coniferous trees such as pines, on the other hand, lose their leaves continuously all year long, so they are never completely bare.
Evergreen trees do lose their leaves but not all at once like deciduous trees.Evergreens drop leaves as they age rather than all at once in the autumn.
Trees that do not loose their leaves are called Evergreens as opposed to Deciduous or those that do loose their leaves in the autumn/winter. Examples of Evergreens are Conifers- blue spruce, cedar- holly, oak.

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.
dont knoow hotty
Bananas dont grow on trees
evergreen trees r those which do not shed their at the particular time of the year.eg-i dont know?
i dont think that there are any leaves in winter
Bananas dont grow on trees
They dont, you must be mistaken.
