Yes, they have chlorophyll. Initially ivy's young leaves are red, later they start to change color as soon as chlorophyll pigment begins to appear thereby green hides the red. Finally in the fall season, their leaves again turn red or orange.
The leaves gradually turn from green to oranges, reds, and yellows at the end of summer because of the chloroplasts in the leaves. Chloroplasts keep the leaves green in the summer because there is so much sunlight in the summertime, and as the sunlight gets less in the fall time, the chloroplasts get weaker and the leaves turn red, orange, and yellow.
Leaves turn red due to the presence of pigments called anthocyanins. These pigments are produced in response to environmental stresses like cold temperatures or excess sunlight. They help protect the leaf from damage and also contribute to the vibrant colors seen in autumn foliage.
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.
The stem has xylem in it. the xylem carries water to leaves, so the leaves turn pinkish.
Because of lack of Phosphorus
Anthocyanin turns leaves red, purple, or blue depending on the pH level of the leaf cells.
Leaves typically turn red and gold in the fall, also known as autumn. This change in color is due to the colder weather and shorter days, which result in the breakdown of chlorophyll in the leaves, revealing the red and yellow pigments that were masked during the summer.
Heaven.
Because it is a deciduous tree.
Deciduous leaves turn red and yellow in the fall due to the breakdown of chlorophyll, which reveals other pigments present in the leaves such as carotenoids (yellow) and anthocyanins (red). As the days get shorter and temperatures drop, the tree stops producing chlorophyll, allowing these other pigments to show through.

The leaves turned a brownish red as autumn approached.
carotens
Maple trees are known for their vibrant red leaves in autumn. Other types of trees that can also turn red in autumn include oak trees, dogwood trees, and sweet gum trees.
