association between blue-green algae and fungi is called??

Answer 1

Lichens: Highly integrated symbiotic associations of millions of algal cells tangled in a lattice of fungal hyphae. Classification: leafy ( foliose), fruticose ( shrubby), and crustose ( crusty).

Answer 2

What are algae? The term 'algae' is used for some lower plants and many, often unrelated groups of microorganisms that are able to perform photosynthesis. Photosynthesis (converting light energy into chemical energy) is performed in parts of the cell called chloroplasts. They can be found in different shapes and colours and in many different organisms. Not all these organisms are green. Diatoms, Chrysophytes and dinoflagellates have yellow to brown chloroplasts. There are brown algae (Phaeophyta), red algae (Rhodophyta) and many other groups of unicellular algae in many shades of green. The blue green Cyanobacteria also photosynthesize. A very diverse groups of freshwater algae are the Chlorophytes or Green algae. Based on the compounds of the photosynthetic pigments and several other characteristics they seem closest related to plants. A common green algae is Hydrodictyon, the water net. It is a related to Pediastrum (top image) But it forms a bag-shaped colony. Like Pediastrum each individual cell can develop into a new colony. You can imagine that since the colony contains thousands of cells Hydrodictyon can reproduce very rapidly. And unlike Pediastrum, Hydrodictyon can grow large, almost 30 cm. in length. Blooms of Hydrodictyon can be a real problem for water treatment plants. The image shows a part of a small colony (left) and three individual cells of a big colony. Inside each of these cells a new colony can be formed. The Fungi (singular fungus) are a kingdom of eukaryotic organisms. They are heterotrophic and digest their food externally, absorbing nutrient molecules into their cells. Yeasts, molds, and mushrooms are examples of fungi. The branch of biology involving the study of fungi is known as mycology. Fungi often have important symbiotic relationships with other organisms. Mycorrhizal symbiosis between plants and fungi is particularly important; over 90% of all plant species engage in some kind of mycorrhizal relationship with fungi and are dependent upon this relationship for survival.[1][2] Fungi are also used extensively by humans: yeasts are responsible for fermentation of beer and bread, and mushroom farming and gathering is a large industry in many countries. Fungi and bacteria are the primary decomposers of organic matter in almost all terrestrial ecosystems worldwide. There are an estimated 1.5 million species of fungi with around 70,000

Answer 3

The term for this association is a mutually beneficial association called the lichen. The fungus forms a morphological structure; the alga species usually has a definite niche within that structure.

Answer 4

More specifically, mutualism. Both algae and fungi mutually benefit from the association. (As opposed to parasitism and commensalism)

Answer 5

lichen ok its associa tion is called symbiosis

Answer 6

a match made in heaven

Answer 7

Answer 8

lichen

Answer 9

It is symbiosis.
