There are levels of cell organization that explain how plant organisms differ and how cells are accommodated to carry the basic processes of nutrition, breathing and reproduction. From this we can distinguish in three basic groups. Protophites are unicellular organisms that can be gathered in colonies, the talophytes are multicellular but without organs, and the cormophytes, which can already organize and differentiate their multiple cells in organs of particular functions.
On this occasion we will address the talophos, among which are fungi, lichens and algae. Continue reading this ecology article where you will learn What are talophos and examples On this group and what common characteristics do you share.
What are the Talophytes
Talophytes are all those organisms that They do not have differentiation of plant organsas are for example flowers, seeds, roots or leaves. On the contrary, they only consist of tissue. The Talófito organism corresponds to a functional and morphological unit that works together to fulfill the vital functions of any living being, such as food or reproduction.
It is important to emphasize that the term Talófito It does not correspond to a taxonomic categorizationbut that is useful to group vegetables and fungi with similar characteristics that we present below.
Characteristics of Talophytes
The body of the talophos is called talo, and is composed of cell sets without differentiating into organs. The components are integrated from each other, but do not distinguish in specialized fabrics in some particular function. The lack of differentiation is a sign of more primitive organisms, but not for this less important for ecosystems.
The Talophytes They are multicellularand consist of several cells gathered. All cells work together to fulfill the basic functions, and remain in communication between them. They have no locomotive capacityremain floating in the water or subject to some substrate. Learn more about unicellular and multicellular organisms: examples and differences.
The cell set can be organized in very varied forms. Some examples are the following:
- Filamentous Talos: The cell division forms filaments with septa between them.
- LAMINARY TALOS: There are two surfaces, one reverse from the other. They are flat and symmetrical.
- SIFOCCLADAL TALO: It can be observed when the filaments have several nuclei, increasing organizational complexity and approaching tissues.
- Plecenchimatic or pseudoparenchimatic talos: The filaments are intertwined between them forming something similar to a fabric, but not properly in a true one.
- Parenchymal talos: In this case, tissues for ordered cell aggregation are formed.
In addition to the aforementioned lack of organs, they do not have vascular tissues with xylem or phloem, which are the tissues responsible for transporting the water, minerals and sap within plants, making it difficult for them to regulate water within them and leaving them vulnerable to changes in moisture, that is, they are non -vascular. This is why the talophytes They live inside wateror are extremely dependent on it. Discover what is xylem and its function.
The talophys are considered “lower plants”, a term that helps us better to understand this classification, but that is not so appropriate, because, as we will see below, not all such such photosynthetic and they are not all plants either.

Examples of talophos
Now that you know what a Talófito is, we will present the groups that make up this categorization.
Algae
They are organisms that They always have chlorophyll and can photosynthesize To get your food. They live inside the water and do not contain structures that give it rigidity outside it, or protect them against desiccation.
Its organization can be a filamentous, with the development of cells that divide one over another to form filaments, or parenchymal, in which wide surfaces similar to tissues are formed, as in the case of red algae. Some algae may also have knots, which are not properly differentiations of tissues, but very close.
Here, you can know the classification of algae.
Fungus
Fungi are organisms lacking chlorophyll and that They need external sources to obtain their food. They break down organic matter and also, they can live as parasites on plants or animals. As well as us, with heterotrophs.
In this case, its organization is a filamentous, where the hyphae septs to form thin filaments composed of cells. The set of filaments in fungi is known as mycelium. The mycelium can be developed on Earth in a so -called fruitful body from which reproductive spores will come out.
Discover the different types of fungi that exist.
Lichens
Lickenes are very interesting organisms that consist of a Symbiotic association of algae and fungicombining chloroplast feeding with the one from inorganic matter. They are a combination of the two groups that we just review. This symbiosis forms very thin and disk -shaped structures, which can grow in a wide variety of surfaces such as trees or rocks. Here it is evident that it is an accumulation of cells that do not form differentiated organs.
