Purple leaves are usually caused by a pigment called anthocyanin. Anthocyanin absorbs green and yellow light, causing them to appear deep red or purple to our eye. These leaves still contain chlorophyll, or else they couldn't photosynthesise, but the green colouration is masked by the strong anthocyanin pigmentation.Purple leaves are usually caused by a pigment called anthocyanin.

Do purple plants have chlorophyll?
The leaves of purple plants still have chlorophyll which looks green to us. So since they have chlorophyll, they can carry out photosynthesis. However, some plants have a lot of compounds called anthrocyanins which can be red or purple in color.
Why are plants green instead of purple?
Cyanobacteria and later plants, have oxygen as the waste product of photosynthesis. Thus slowly Earth became oxygenized. This Great Oxygenation Event wiped out most of the anaerobic organisms including the purple bacteria. So plants are green because chlorophyll is more suited for a blue or a red sun.
Why are some plants red and purple?
Chlorophyll uses this electromagnetic energy, along with carbon dioxide and water, to make glucose and oxygen. Most plants also have other pigments: carotenoids, which usually appear yellow to orange, and anthocyanins, which are red to purple.
Why do some plants have purple under leaves?
Flowering Plants Leaves of tropical plants such as Leptospermum recapture light with purple pigment. Purple pigments on the underside of leaves in rainforest plants help maximize light absorption through reflecting light back up int the leaf. through reflecting light back up int the leaf.
Why are some flowers purple?
Many of the actual chemicals in flower petals that give them different colors are called anthocyanins. These are water-soluble compounds that belong to a bigger class of chemicals known as flavonoids. Anthocyanins are responsible for creating the colors blue, red, pink, and purple in flowers.
Can plants purple?
The researchers predict plants on that planet would be yellow or orange. Another star, AD Leo, produces peaks of radiation in the UV spectrum. The team predict that plants on a planet bathed in this high-energy glow would be purple.
Can plants be black?
Black-leaved plants exist today and may have existed in the past but could have been eliminated for any number of reasons.
Is the Earth purple?
The earliest life on Earth might have been just as purple as it is green today, a scientist claims. Ancient microbes might have used a molecule other than chlorophyll to harness the Sun's rays, one that gave the organisms a violet hue.
Why are so many wildflowers purple?
Flowers of many species have purple stripes on their petals, which are called nectar guides. These guides clearly lead toward the reproductive structure, or center, of the flower, increasing the chances for pollination, according to Griffin.
