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.
What else can I help you with?
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.
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.
What are the parts and functions of algae?
Algae are primarily composed of three main parts: thallus (the body), holdfast (anchor), and reproductive structures. The thallus can vary in shape and size, serving as the main site for photosynthesis, where algae convert sunlight into energy. The holdfast anchors the algae to surfaces, helping them remain in place in their aquatic environments. Reproductive structures facilitate the production of gametes or spores for reproduction, ensuring the continuation of the algae species.
What are heterotrichous alga?
It is a type of thallus in algae. In this type the thallus is very much evolved and differentiated into prostrate and erect systems. e.g.:-Ectocarpus,Coleochaete.Both the prostrate and the erect systems may be well developed or there is progressive elimination of prostrate or erect systems
Why are algae called thallophytes?
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.

What is a lichen thallus?
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.

Are the stem holdfast and blade of brown algae the same as stems roots and leaves of land plants?
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.
What is a thallus?
A thallus is the main body of a plant or fungus that lacks roots, stems, or leaves. It is a simple, undifferentiated structure that is characteristic of lower plants like algae, lichens, and liverworts.
Is subcuticular suturing a complex repair?
no
Are ulva unicellular?
No, ulva is a multicellular green algae. It consists of many cells working together to form a thallus, which is the plant body of the alga.
What are heterotrichous alga?

What is the difference between a thallus and hypha?
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.
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.
Do ferns have a thallus and if so are they still vascular plants?
Yes ferns do have a thallus, and yes they are vascular plants.
