Which category of lichen thallus either stands up or hangs down?
Foliose lichens have a thallus that is leafy and generally stands up or hangs down from the substrate. This type of lichen has separate upper and lower surfaces, with the lower surface attached to the substrate.
What do the fungal threads of lichen proudece?
The fungal threads of lichen produce a structure called a thallus, which is a symbiotic association of the fungus with algae or cyanobacteria. The fungal threads provide structure and protection for the algae or cyanobacteria while receiving nutrients from them through photosynthesis.
Why is bread mold regarded as thallus?
Bread mold is regarded as a thallus because it is a simple, undifferentiated structure without specialized tissues. Thallus is a term used to describe the body of lower plants, such as fungi, that lacks true roots, stems, or leaves. Bread mold's thallus-like structure allows it to absorb nutrients directly from its surroundings, aiding its growth and reproduction.
What is an example of a lichen?
An example of a lichen is the reindeer lichen found in arctic and subarctic regions. This lichen forms a symbiotic relationship between a fungus and an alga, growing on rocks, soil, or tree branches. Reindeer lichen is an important food source for animals like reindeer and caribou.
What two organisms form a lichen?
A lichen is a mutualistic relationship between a fungus and either algae or cyanobacteria. The fungus provides structure and protection, while the algae or cyanobacteria provide nutrients through photosynthesis.

Does lichen clean the air?
Yes, lichen can help clean the air by absorbing pollutants, including sulfur dioxide and heavy metals, through their thallus. They also absorb particulate matter, which can improve overall air quality. Additionally, their sensitivity to air pollution makes them useful bioindicators for assessing environmental health. Thus, lichen plays a beneficial role in monitoring and improving atmospheric conditions.
What are the physical characteristics of Iceland moss?
Iceland moss is a lichen that typically grows in tufts or mats on the ground. It has a pale green or grayish appearance and is often wrinkled or uneven in texture. The plant's thallus is foliose, meaning it is leaf-like in structure, and it can reach lengths of up to 10 cm.
The body portion of algae is called?
The body portion of algae is called thallus. It is the main structure of the algae that carries out photosynthesis and other functions.
Do ferns have a thallus and if so are they still vascular plants?

Thallus organisation in algae?
Algal thalli can be simple (unicellular or colonial) or complex (multicellular with differentiated structures). Simple thalli lack true tissues and organs, while complex thalli exhibit various levels of differentiation, such as holdfasts for attachment, stipes for support, and fronds for photosynthesis. Thallus organization varies among different algal groups, reflecting their evolutionary history and ecological adaptations.
