Plants in the ocean require light for photosynthesis. How does light enter the ocean, making photosynthesis?

Question

Thank you for all answers so far. I think what is required for this assignment is a more technical explanation... if anyone can help. Thanks again.

Answer 1

the light rays reach the plants through the water....What exactly are you asking here?

Of course the light the plants receive under water, when compared to light received by plants on land, is relatively degraded, as the water and other organisms living in it absorb some wavelengths of light....

Answer 2

Light can penetrate through the water to reach plants. My botany teacher said water plants do not exist anymore however. Apparently they are all considered to be protists (things like kelp, algae, seaweed.. etc.)

Red light can penetrate the farthest, that is why red algae is found so deep in many bodies of water.

Answer 3

Various wave lengths of light penetrate the ocean waters but quickly is absorbed by phytoplankton, seaweeds and seawater.  Some light penetrates as deep as 700 feet where a red seaweed grows!  At that depth there is not enough light for a human to see objects!  Some ecologists have estimated most of the oxygen we breathe comes from photosynthesis of algae growing in the oceans of the world!

Answer 4

This may help but some plants grow on other plants called budding to go through the process of Photosynthesis. By using budding they can reach higher than the plant they grow on. The higher, the more sunlight they can reach. Plants do alot of different things to survive through secondary succession.
