What is these deep sea plants different from all other green plants and leaves? Aren’t they doing photosynthesis either?

How does it become red if it does photosynthesis?

When the light hit a random object, it is absorbed or reflected.

When reflected, it gives a reasonable color. The color that appears, the color reflected when the light hits that object. At one -to -one time, the color of an object depends on which colors it absorbs. For example, as we all know, the leaves in the tree are green and this green color is caused by chlorophyll.

In fact, white light (a mixture of all colors) hits the leaf and reflects the green light by absorbing chlorophyll, blue and red light on the leaf. For this reason, an object needs to absorb blue and green light and reflect the red light in order to look red for sea seaweed.

For example, the water in the oceans sucks more, especially red light than other colors. The blue light is reflected back and therefore the oceans look blue.

On the other hand, photosynthesis for plants to survive.

In fact, there are no plants beyond a few hundred meters below the ocean and seas. Because the sun’s rays do not reach deep and cannot perform photosynthesis. However, some red algae are out of this generalization.

Unlike others, these red plants have a “Fikoerithrin” pigment. This pigment reflects the red light and absorbs blue light. For that reason, the colors are red.

In addition, the blue light, as long as a longer wave length penetrates to deeper areas than a random light, these pigments allow red algae to make photosynthesis. In other words, red algae thus continues to perform photosynthesis without sunlight and have this unique red color.
