Because of the resparetion. Resparation means breathe. Leaves breathe in thecarbon dioxide and breathe out the oxygen.
The yellow leaves will turn in to green gradually when the plant is put back in the sun.
Lily leaves turn yellow due to a lack of nutrients, such as nitrogen, or excessive watering, which can lead to root rot. This causes the leaves to lose their green color and turn yellow.
Honey locust leaves are normally green. However, they turn yellow for several reasons. One is that they are simply new leaves that have not yet gotten their green coloring. Two is that they turn yellow in fall, and are about to drop off the tree.
Plant leaves turn yellow due to a lack of chlorophyll, which is the pigment responsible for the green color of leaves. This can be caused by factors such as nutrient deficiencies, diseases, pests, or environmental stress.
tulip leaves are green but when the turn yellow you need to reduce watering. :) hope this helps
Plant leaves turn brown and yellow due to a process called senescence, which is a natural aging process in plants. During senescence, chlorophyll (the green pigment in leaves) breaks down, causing the leaves to lose their green color and turn yellow. Additionally, factors such as nutrient deficiencies, diseases, pests, and environmental stress can also contribute to the browning and yellowing of plant leaves.
Leaves on plants turn yellow due to a lack of chlorophyll, which is the green pigment responsible for photosynthesis. This can be caused by factors such as nutrient deficiencies, disease, or environmental stress.
Leaves turn yellow in the fall because the chlorophyll, which gives them their green color, breaks down as the days get shorter and cooler. This reveals the yellow and orange pigments that were always present in the leaves but were masked by the chlorophyll.
Leaves turn yellow because of a process called chlorophyll breakdown. As the days get shorter and temperatures drop in the fall, the chlorophyll in the leaves breaks down, revealing the yellow and orange pigments that were masked by the green chlorophyll during the summer.
Because when the Chlorophyll molecules - that gives leaves their Green color - disintegrate they can't make the plant Green anymore - Yellow is the next color to appear and in turn vanish to make way for the Red colors.
Leaves turn yellow during the fall season because the chlorophyll, which gives leaves their green color, breaks down as the days get shorter and cooler. This allows other pigments in the leaves, such as carotenoids and anthocyanins, to become more visible, resulting in the yellow and red colors we see in the fall.
Some trees have yellow leaves in summer because of a process called chlorosis, which occurs when the tree lacks certain nutrients like iron or magnesium. This can cause the leaves to turn yellow instead of staying green.
