Both bryophytes and tracheophytes have developed conducting tissues consisting of cells specialized for the distribution of food and water throughout the plant body.

Do bryophytes have specialized tissue?
Bryophytes are seedless plants without specialized water-conducting tissues.
Do bryophytes have water-conducting cells?
Yes, some bryophytes do have specialized cells for conducting either water or sugars through their plant body, however, the walls of these cells are not strengthened by the compound lignin, so they are not termed xylem and phloem.
How do bryophytes conduct water?
Explanation: The members of Bryophytes are nonvascular plants. They carry out the transport of water and nutrients via diffusion process. Lack of vascular tissues, the members of Bryophytes absorb water and nutrients at the surface and transport the materials from cell to cell.
What are the conducting tissues in bryophytes?
A polarized cytoplasmic organization and a distinctive axial system of microtubules is present in the highly specialized food-conducting cells of polytrichaceous mosses (leptoids) and in less specialized parenchyma cells of the leafy stem and seta in other mosses including Sphagnumn.
Why do bryophytes usually live in aquatic or moist environment?
Bryophytes also need a moist environment to reproduce. Their flagellated sperm must swim through water to reach the egg. So mosses and liverworts are restricted to moist habitats.
Do bryophytes have chlorophyll?
Similarities to algae and vascular plants
Green algae, bryophytes and vascular plants all have chlorophyll a and b, and the chloroplast structures are similar. Like green algae and land plants, bryophytes also produce starch stored in the plastids and contain cellulose in their walls.
Do bryophytes produce seeds?
Bryophytes produce spores, rather than seeds, and have no flowers.
How do bryophytes obtain water and CO2?
How do bryophytes obtain water and CO2? They absorb both CO2 and water directly from the environment, without passing through stomata or roots.
Why do bryophytes need water?
Bryophytes though grow on soil but need water for sexual reproduction. ... So, in order to accomplish fertilization sperm must be provided with water. So that sperm can whip its flagella in water and swim to egg to fertilize it.
How do bryophytes that do not have vascular tissue get enough water and minerals?
Most bryophytes are small. They not only lack vascular tissues; they also lack true leaves, seeds, and flowers. Instead of roots, they have hair-like rhizoids to anchor them to the ground and to absorb water and minerals (see Figure below).
How do bryophytes survive without vascular tissues?
Characteristics of Nonvascular Plants
Bryophytes occupy niches in moist habitats, but, as they lack vascular tissue, they are not very efficient at absorbing water. The rhizoids of a bryophyte may be so fine that they are just one cell thick. Bryophytes also depend on moisture to reproduce.
What are the conducting tissues?
The tissue of higher plants consisting mainly of xylem and phloem and occurring as a continuous system throughout the plant: it conducts water, mineral salts and synthesized food substances and provides mechanical support. They are also called as vascular tissues.
What are the two conducting tissues in plants?
The vascular system consists of two conducting tissues, xylem and phloem; the former conducts water and the latter the products of photosynthesis.
What is the water conducting tissue generally present in Gymnosperm?
Gymnosperms do not have vessels in their xylem. Water conducting tissues present in them are tracheids.
