How do brown and red algae synthesise their food in the deep ocean?
Answer Expert Verified Plants in deep ocean receive oxygen from water and get access to sunlight. Due to presence of chlorophyll, pigments of red and brown help in masking predominant green pigments of photosynthesis. As a result, they easily prepare their food and survive for long.
How can plants grow deep in the ocean without sunlight?
This process is called photosynthesis. In the deep ocean, many hundreds of meters away from the sun’s rays, another process is taking place: chemosynthesis. Tiny microbes use chemical energy instead of light to combine water and carbon dioxide to make sugar.
Why did land plants lose some of the accessory pigments present in brown and red algae?
Why did land plants lose some of the accessory pigments present in brown and red algae? Sunlight is not filtered by water or other algae on land; therefore, there is no need to collect light at additional wavelengths made available by other pigment coloration.
How do you think the plants like red and green algae prepare their food in deep oceans where sunlight can hardly reach?
8) Deep in the ocean, sunlight can hardly reach, yet plants such as brown and red algae are found here. How do you think they are able to synthesis their food? Some have special adaption to low light and can undergo photosynthesis.
How does red algae survive in the ocean?
They also can survive at greater depths in the ocean than some other algae, because the phycoerythrin’s absorption of blue light waves, which penetrate deeper than other light waves do, allows red algae to carry out photosynthesis at a greater depth.
Why is red green brown algae found in deepest waters?
Explanation: Red algae is mostly likely to be found in deep water. This has to do with the different wavelengths of light and how deep they can penetrate water. Red light has the longest wavelength of the visible spectrum which means it penetrates water the least.
Are there plants in the deep ocean?
From 1,000 meters below the surface, all the way to the sea floor, no sunlight penetrates the darkness; and because photosynthesis can’t take place, there are no plants, either. Animals that live in the abyssal zone feed on detritus raining down from above—or on each other.
How do plants survive in deep ocean?
TL;DR: Ocean plants have developed adaptations such as the ability to absorb nutrients from water, the ability to float and the ability to anchor themselves to rocks on the ocean floor in order to thrive in their challenging environment.
How do mosses contribute to returning nitrogen to the soil quizlet?
Mosses decompose rocks and release nitrogen.
How are bryophytes and seedless vascular plants alike?
Explanation: Both bryophtes (the mosses) and seedless vascular plants (mostly ferns) rely on water fertilization, do not have complex xylem and phloem, do not have complex gametophytes, and simple root like systems instead of the roots you see in other vascular groups.
How red algae can remain alive in deep sea?
Deep Sea Dweller Like all algae, red algae depend on photosynthesis to produce food. Most varieties of algae live near the surface of the water in order to get enough sunlight to live. Since they can absorb blue light, red algae can live in much deeper water where light of long wavelengths — like red — can’t reach.
Which algae live in deep sea?
Red algae
Explanation: Red algae is mostly likely to be found in deep water. This has to do with the different wavelengths of light and how deep they can penetrate water. Red light has the longest wavelength of the visible spectrum which means it penetrates water the least.
How do plants survive in the deep ocean?
Plants in deep ocean receive oxygen from water and get access to sunlight. Due to presence of chlorophyll, pigments of red and brown help in masking predominant green pigments of photosynthesis. As a result, they easily prepare their food and survive for long. After their death, they fall down.
How do Plants synthesise food in the ocean?
Deep in the oocean sunlight can hardly reach but yes the plants can synthesise their food because some chemicals reactions take place,they take the nutrients from the water and also they are adapted to that mode of nutrition. Was this answer helpful?
How deep in the ocean can the sun’s light travel?
Sunlight entering the water may travel about 1,000 meters (3,280 feet) into the ocean under the right conditions, but there is rarely any significant light beyond 200 meters (656 feet). Such a minuscule amount of light penetrates beyond a depth of 200 meters that photosynthesis is no longer possible.
Why do algae prepare food like other plants?
All algae contain chlorophyll. The pigments of red and brown algae mask the predominant green photosynthetic pigments. Thus prepare food like other plants. Algae receive sunlight and oxygen throughout life and after death only they fall to the bottom of the ocean and decay.
