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.

A lichen thallus is the main body of a lichen, which consists of an algal or cyanobacterial partner (photobiont) living in a symbiotic relationship with a fungal partner (mycobiont). The thallus is the part of the lichen responsible for photosynthesis and nutrient absorption.

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.

Thallus pores facilitate the exchange of gases, such as oxygen and carbon dioxide, in lichens. They also regulate water vapor exchange and help in nutrient absorption and waste removal. Thallus pores play a crucial role in the overall physiology and metabolism of lichens.

An algae with a subcuticular thallus may have developed this structure to provide protection from desiccation or to enhance gas exchange. The subcuticular thallus allows the algae to remain hydrated and obtain necessary resources from its environment while minimizing water loss and potential damage.

Mushrooms are diploid, meaning they have two sets of chromosomes - one set from the male parent and one set from the female parent. This allows them to undergo sexual reproduction by producing spores that contain a mixture of genetic material from both parents.

The spores of a fern are ONE step of its reproduction. This may form a pro-thallus, which when ripe will produce male and female parts. The male sperm of a pro-thallus is motile (!) and provided it is moist, it will fertilize the female seed. From this fertilization, a new fern will arise.

A thallus is a simple, undifferentiated vegetative body found in some lower plants like algae and fungi, while a hypha is a thread-like structure composed of fungal cells that make up the body of a fungus. Thalli are typically found in algae, lichens, and some fungi, while hyphae are specific to fungi.

No, the holdfast of brown algae functions to anchor the algae to a substrate, similar to roots in land plants. The blade serves as the main photosynthetic structure, akin to leaves in land plants. Brown algae do not have traditional stems like land plants.

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.

Anthoceros is referred to as a synthetic genus because it was created to accommodate various species that share certain morphological characteristics, even though they actually belong to different lineages. This grouping was based on similarities in reproductive structures rather than evolutionary relationships.

Holocarpic fungi are fungi that produce spores within a single undivided sporangium or structure, without any differentiation between vegetative and reproductive structures. This is in contrast to the more common type of fungi, called Eucarpic fungi, which have separate vegetative and reproductive structures.

Heterotrichous algae are a group of algae that have two different types of flagella: whiplash and tinsel. The whiplash flagella are longer and used for movement, while the tinsel flagella are shorter and used for feeding. Heterotrichous algae are found in various aquatic environments and play a role in nutrient cycling.

An example of Hepatophyta is the species Marchantia polymorpha, commonly known as liverwort. It is a non-vascular plant that typically grows in damp or aquatic environments. Liverworts are characterized by a flattened, ribbon-like body called a thallus.

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.

The thallus structure of lichens helps in respiration by providing a large surface area for gas exchange to occur. This structure allows lichens to efficiently absorb and release oxygen and carbon dioxide required for respiration.

They are microscopic, absorptive organisms that reproduce both sexually and asexually and are composed of mycelia, or a tube-like vegetative body (all of an organism's mycelia are called its thallus). The name "water mould" refers to the fact that they thrive under conditions of high humidity and running surface water

Caulerpa racemosa, also known as sea grapes, consists of thallus (leaf-like structures), rhizoids (root-like structures), stolons (stem-like structures), and reproductive structures called sporangia. These components help the algae to anchor itself, absorb nutrients, and reproduce efficiently in its marine environment.

The earliest plants, known as bryophytes, had simple structures with no distinct organs like leaves, stems, or roots. They had a structure called a thallus which served as a basic form of a plant body to absorb nutrients and water. Over time, as plants evolved, they developed more complex structures with specialized organs.

That entirely depends on what you call history books. Remember some people do believe that the bible is historical, and to be honest some parts of it are historically accurate other parts are more like a written verbal history.
'A' Jesus was mentioned in some Roman records, but to be honest Jesus was a fairly common name back then in that area so it's highly likely that there was more than one.
The most solid evidence we have which does not come from the gospels and from a different source was the Greek Thallus who mentioned the crucifixion of Jesus in his book "The Third History". But this was allegedly written 20 years after Jesus's death and doesn't exist in it's entirety. Thallus's books were mostly destroyed and the expcert we get mentioning Jesus is from the quotes by Sextus Julius Africanus in his book "History of the World".
It's important to consider that Thallus was a Pagan not a Christian so if the account repeated by Sextus is correct then it is significant that he would record this. It must have made an impression otherwise why would he have bothered?
The 9th-century Christian chronologer George Syncellus cites Sextus as reporting Thallus as saying:
"This event followed each of his deeds, and healings of body and soul, and knowledge of hidden things, and his resurrection from the dead, all sufficiently proven to the disciples before us and to his apostles: after the most dreadful darkness fell over the whole world, the rocks were torn apart by an earthquake and much of Judaea and the rest of the land was torn down."
That's it. Of course it is entirely possible that this was fabricated by Sextus who by that time may have been a closet Christian and wanted to historicise Jesus. But I leave that decision to you.

For fungi and some lichen, reproduction is just by simple division, or by the use of minute spores.
For ferns, spores are produced by the adult plant, and these grow in a suitable moist environment into a pro-thallus, which produces egg and (motile) sperm cells, which then fertilize with their mate from different pro-thallus. Thus a new final plant is produced.

A gemmae cup is a cup-shaped structure found in liverworts that contains gemmae, which are small, asexual reproductive structures. Gemmae cups are usually located on the upper surface of the thallus (body) of the liverwort plant. They are specialized for dispersing gemmae, which can give rise to new plants under suitable conditions.

Algae are called thallophytes because they are simple, plant-like organisms that lack true roots, stems, or leaves. Thallophytes have a body plan known as a thallus, which is a undifferentiated structure that lacks specialized tissues. Algae exhibit this structure, hence the classification as thallophytes.
