Are there plants without roots?

Plants, if we refer to the Plantar Kingdom, are a very extensive group of organisms characterized by being photosynthetic, with cellulose cell walls and without voluntary locomotor capacity. within the plant kingdom Embryophytes and several groups of algae, all evolutionarily related, are included.

The colloquial use of the word “plant” coincides with the group of embryophytes. Although there are embryophytes that live in the aquatic environment, most are terrestrial, so they are also known as terrestrial plants.

Although it is common to associate roots and land plants, the truth is that there is a group of plants that do not have roots or any other type of vascular tissue. They are known as non-vascular plants or lower plants, although their distribution and evolution is comparable to higher plants that have vascular roots and tissues.

plants with roots

the root is a specialized organ only appears in a group of embryophytes, the tracheophytes (Tracheophyta), also known vascular or superior plants. These plants are characterized, in addition to having roots, for having two types of vascular tissue:

xylem: transports water, minerals and other nutrients from the root to the leaves. pholema: transports organic nutrients, mainly glucose, and some inorganic nutrients, from the photosynthetic and autotrophic part of the plant to the non-photosynthetic part, that is, from the leaves to the root.

Among the functions of roots, the most prominent are:

Floor fixing and support Absorption of water and minerals Accumulation of reserves Contribution to soil formation

The group of vascular plants includes mosses, ferns and seed plants (gymnosperms and angiosperms).

plants without roots

The other large group of embryophytes are the non-vascular plants in the east without roots or specialized vascular tissues. Among them we find mosses, liverworts and hornworts, all characteristic of humid environments, since they absorb water directly from the environment.

Non-vascular plants form the group of bryophytes in the broad sense (Bryophyta sensu lato), mosses being bryophytes in the strict sense. All studies indicate that bryophytes are the closest living relatives of green algae and that they were the first plants to evolve 500 million years ago.

In addition to not having vascular tissues, bryophytes are characterized by the alternation of diploid generations and generations of haploid gametophytes, a characteristic that in vascular plants occurs only in ferns and lycopods.
