How are green algae different from cyanobacteria quizlet?
Algae and plants both have chloroplasts and chlorophyll. However, cyanobacteria isn’t truly bacteria because they do not have an organized nucleus, chloroplasts, or organelles. They have peptidoglycan in their cell walls which makes them prokaryotes, while algae are eukaryotes.
How are true algae and cyanobacteria similar and different?
Algae are small unicellular organisms whereas cyanobacteria are multi-cellular organisms and larger in size. Cyanobacteria lack a nucleus and mitochondria. They perform photosynthesis by using water as a source of electron and create oxygen. Green algae are found in lakes, oceans and fresh water bodies.
Is cyanobacteria a green algae?
Cyanobacteria, also referred to as blue-green algae, are microscopic organisms that live primarily in fresh water and salt water, at the surface and below.
What is the difference between red algae and green algae?
The main difference between red brown and green algae is that red algae contain chlorophyll a, chlorophyll d, and phycoerythrin, while brown algae contain chlorophyll a, chlorophyll c, and fucoxanthin and green algae contain chlorophyll a, chlorophyll b, and xanthophylls.
Why are some green algae red?
Red algae are red because of the presence of the pigment phycoerythrin; this pigment reflects red light and absorbs blue light.
How does red algae get energy?
All algae get their energy from the sun from photosynthesis, but one thing that distinguishes red algae from other algae is that their cells lack flagella, the long, whiplike outgrowths from cells that are used for locomotion and sometimes serve a sensory function
Do red algae produce oxygen?
Like most plants, many algae produce oxygen during the daylight as a by-product of photosynthesis. At night these algae consume oxygen, but usually much less than was produced during the daylight.
Why can red algae live so deep in the ocean?
Explanation: 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 is the deepest dwelling algae?
Where is green algae found?
Most green algae occur in fresh water, usually attached to submerged rocks and wood or as scum on stagnant water; there are also terrestrial and marine species. Free-floating microscopic species serve as food and oxygen sources for aquatic organisms.
Which algae lives deepest water?
Which is the deepest dwelling algae red green or brown Why?
Answer by Isha Agarwal This phycobilin/phycoerythrin can absorb the blue light and use it for photosynthesis, thus using the little solar energy that reached the deepest part of the ocean for manufacturing food. Hence, the red algae is able to survive the deepest quarters of the oceans while the others can’t.
Which is likely to be found in the deepest waters?
Which algae is used as food?
The most commonly consumed macroalgae include the red algae Porphyra (nori, kim, laver), Asparagopsis taxiformis (limu), Gracilaria,Chondrus crispus (Irish moss) and Palmaria palmata (dulse), the kelps Laminaria (kombu), Undaria (wakame) and Macrocystis, and the green algae Caulerpa racemosa,Codium and Ulva (see Tseng.
Can you live off of algae?
To survive, we need to reinvent the way we farm and eat. Experts say algae could be a possible solution. Unlike most crops, it doesn’t require fresh water to flourish. Meat uses up a lot of our finite resources, like water and land, not just for the animals but to grow their food, too
What are the benefits of taking blue-green algae?
Some people use blue-green algae for treating precancerous growths inside the mouth, twitching of the eyelids, boosting the immune system, improving memory, increasing energy and metabolism, improving exercise performance, lowering cholesterol, preventing heart disease, healing wounds, and improving digestion and bowel ..
