2.

A lichen is
- Additive
- Symbiosis
- Together
- Parasite
Correct Answer

A. Symbiosis

Explanation

A lichen is a type of organism that is formed through a symbiotic relationship between a fungus and an alga or a cyanobacterium. In this relationship, both the fungus and the alga/cyanobacterium benefit from each other. The fungus provides a protected environment and absorbs water and nutrients for the alga/cyanobacterium, while the alga/cyanobacterium performs photosynthesis and provides food for the fungus. This mutualistic interaction between the two organisms is known as symbiosis.

One part of a lichen is a microscopic
- Species
- Plant
- Alga
- Organ
Correct Answer

A. Alga

Explanation

Lichens are composite organisms that consist of a symbiotic relationship between a fungus and an alga. The alga is a crucial component of the lichen structure, as it provides the food source through photosynthesis. The fungus, on the other hand, provides protection and a suitable environment for the alga to thrive. Therefore, it is correct to say that one part of a lichen is a microscopic alga.

4.

One part of a lichen is a filamentous
- Fungus
- Bite
- Jar
- Organ
Correct Answer

A. Fungus

Explanation

Lichens are composite organisms that consist of a symbiotic relationship between a fungus and an alga or a cyanobacterium. The fungus is the dominant partner and provides the structural support and protection, while the alga or cyanobacterium provides the photosynthetic ability to produce food for both partners. The filamentous nature of the fungus allows it to form a network of hyphae, which helps in anchoring the lichen to its substrate and absorbing nutrients. Therefore, the correct answer is fungus.

Letharia vulpina is known as
- Dig moss
- Fig
- Wolf lichen
- Dog moss
Correct Answer

A. Wolf lichen

Explanation

Letharia vulpina is commonly referred to as "Wolf lichen." This is because it is a type of lichen that resembles the fur of a wolf. Lichens are composite organisms consisting of a fungus and an alga or cyanobacterium living in a mutualistic relationship. Letharia vulpina specifically has a bright yellow-green color and can be found in forests and mountainous regions. Its name "Wolf lichen" is a descriptive term that helps identify this particular species of lichen.

Flavoparmelia caperata has leaf-like structures, so it is
- Foliose
- Figgy
- Plant
- Mossy
Correct Answer

A. Foliose

Explanation

Flavoparmelia caperata is classified as foliose because it has leaf-like structures. Foliose refers to lichens that have a lobed or leafy appearance, with the thallus (body) being flat and expanded. This type of lichen is characterized by having distinct upper and lower surfaces, with the upper surface usually being green or brown and the lower surface being white or black. The leaf-like structures of Flavoparmelia caperata fit this description, making it a foliose lichen.

It is a branch of
- Math
- Science
- Mycology
- Art
Correct Answer

A. Mycology

Explanation

Mycology is the scientific study of fungi, including their biology, classification, and ecology. Fungi play a crucial role in various ecosystems and have significant impacts on human health and agriculture. Therefore, mycology is a branch of science that focuses specifically on the study of fungi.

Who is the father of lichenology?
- Erik Acharius
- Isaac Newton
- Darius
- Carl
Correct Answer

A. Erik Acharius

Explanation

Erik Acharius is considered the father of lichenology because he made significant contributions to the study and classification of lichens. He developed a systematic approach to identify and classify lichens based on their morphological characteristics. Acharius also established the first comprehensive classification system for lichens, which served as the foundation for future research in the field. His work laid the groundwork for the understanding of lichens and their ecological importance, making him a key figure in the field of lichenology.

Acharius was a student of
- Carl Linnaeus
- Charles Darwin
- Plato
- Socrates
Correct Answer

A. Carl Linnaeus

Explanation

Acharius was a student of Carl Linnaeus, who was a renowned Swedish botanist and physician. Linnaeus is considered the father of modern taxonomy and is known for his work in classifying and naming organisms. Acharius, a Swedish botanist himself, studied under Linnaeus and made significant contributions to the field of lichenology.

Caloplaca marina grows like an orange crust coating the rock, so it is
- Fig
- Mossy
- Crustose
- Rocky
Correct Answer

A. Crustose

Explanation

Caloplaca marina is described as growing like an orange crust coating the rock. This indicates that it forms a crust-like structure on the surface of the rock. Therefore, the correct answer is "Crustose," which refers to organisms that grow in a crust-like manner.
