If they are over or under watered they can turn yellow. But if kept in the dark they turn yellow because the chlorophyll (which gives plants its green hue) is unable to absorb energy from light to start the process of photosynthesis. If your plants are turning yellow, try and find a sunnier spot, or get a lamp for it.
Because they are dead leaves. If there's no sunlight they will die and turns to yellow.
This is called photosynthesis. Plants use the energy from the sun to convert certain organic salts, carbon dioxide and water which are converted to carbohydrates needed by the plants to make them grow and stay healthy.
They either haven't had enough sunlight or water. Or maybe the leaves haven't even blossomed yet? :)
The two types are the green and yellow leaves
I think it's a deficiency of nitrates, which help plants to produce chlorophyll, and which is the pigment that turns leaves green, and without it, leaves can become yellow.
The green pigment found in plants is chlorophyll, which produce food for the plant. In the Autumn, the chlorophyll starts to die (if that is the right word) and the leaves become brown, red, orange or yellow. In the Spring the plant retains its usual green colour.
What is the green substance in leaves of plants? The green substance in the leaves of plants is a pigment called chlorophyll
The wheat streak mosaic is characterized by yellowing plants, with leaves that have a mottled yellow and green appearance
A lack of phosphates in plants causes poor growth and leaves that turn a dull green with purple or yellow tints. Sometimes leaf margins may become slightly scorched. HaSr
If you mean the green pigment in leaves of plants, it's called the chlorophyll. But if you're really referring to the green leaves of plant, then sorry, I don't know. The answer would still be green leaves, if you're looking for the name of the green leaves of plants.
Bhendi yellow vein mosaic is a disease that infects plants and causes yellow and green alternating patches on the leaves. Plants that have the disease need to be burned. The disease was first identified in 1924.
Xanthophyll is a yellow pigment present in green leaves and plants.
If you're talking about how they're not green, they still use photosynthesis. It's just a much smaller amount than most plants use. (Photosynthesis is what makes most plants look green.)
there is a plant that dosent have green leaves
yes they should have green leaves. Green leaves are green because they have chlorophyll which is needed for flowers.
