During photosynthesis there is the process where chlorophyll makes the leaves turn green. As fall comes the trees stop growing and this makes the process to stop. So when chlorophyll stops running through the leaves, they start to turn different colors. Than by winter all the leaves fall off and in spring they grow back again
Since the leaves turn red in the fall it is not evergreen... the leaves are dying and that's why they turn red... Soon after the leaves turn red they will fall to the ground.
on of the most common reasons why leaves fall off yucca plants is due to over watering
the tree stops making chlorophyll in the winter. (the chlorophyll is the stuff in the leaves that makes them green)
fall
Yes some plants have leaves which fall of like mango leaves . But there are some plants of which leaves do not fall , like oak leaves.
becuase its the fall so the season changes the leaves so they can fall off and make new ones sprouting on a tree
In the autumn or fall, leaves begin to lose their chlorophyll and turn different colors. After that, the leaves lose their cohesion and fall to the ground.
Leaf Chromatography
Deciduous trees leaves fall in the autumn and rot on the ground and form a mulch which in turn feeds the tree.
They change because they have a chemical called choralfil that makes the leaves green and when it gets doesn't get enough water and sunlight the choralfil dies reason for that is that in the fall, the days get shorter and the plants get less sunlight, the leaves turn from green to either red, yellow and brown.
because the leaves get really old
