Stonework

Question 3

What are the types of Lichens?

Crustose

Foliose

Fruticose

Squamulose

Question 4

what is Lichen?

Answer 4

A lichen is a symbiosis of algae or cyanobacteria living among filaments of multiple fungi species, along with a yeast embedded in the cortex or “skin”, in a mutualistic relationship.

They come in many colors, sizes, and forms and are sometimes plant-like, but are not plants. They may have tiny, leafless branches (fruticose); flat leaf-like structures (foliose); grow crust-like, adhering tightly to a surface (substrate) like a thick coat of paint (crustose), have a powder-like appearance (leprose); or other growth forms.

Question 5

What is cyanobacteria?

Answer 5

Cyanobacteria , also called Cyanobacteriota or Cyanophyta, are a phylum of autotrophic gram-negative bacteria[4] that can obtain biological energy via oxygenic photosynthesis. The name “cyanobacteria” (from Ancient Greek κύανος (kúanos) ‘blue’) refers to their bluish green (cyan) color,which forms the basis of cyanobacteria’s informal common name, blue-green algae, although as prokaryotes they are not scientifically classified as algae.

Question 6

What is a photobiont?

Answer 6

A photobiont refers to the photosynthetic component of a lichen, which may be either a green alga or a cyanobacterium.

Question 7

What is a mycobiont?

Answer 7

Mycobiont is the fungal component in a lichen. The two main phyla of fungi involved in the formation of lichen are Ascomycetes and Basidiomycetes. Therefore, the lichens associated with the respective phyla of fungi are known as ascolichens and basidiolichens.

Question 8

What is ascomyceta?

Answer 8

Sac fungi, that shoots spores.
