Non Vascular plants such as moss and liverwort lack vascular tissue or transport tissues. The plants are dependent on osmosis and diffusion for the movement of water and nutrients through their cells. These plant also lack a true root system, stems, or leaves without the vascular tissue to support them.

True Xylem & phloem are found every where there are vascular bundles including roots, stems, leaves, flowers, fruits etc.
Ethnobotany, which is a mix of the words ethnology (the study of culture) and botany (the study of plants). Ethnobotany seeks to study the relationships that exist between humans and plants.
They lose their leaves and then they grow back in the spring.
In aquatic environments (oceans, lakes, rivers), algae are dominant over vascular plants; but vascular plants do exist in those places. There are also places on land where nonvascular plants -- mosses, liverworts, and hornworts -- are dominant over vascular plants: they tend to be very, very moist and/or lack enough soil for anything larger to get a foothold.
"Seaweed" is loose colloquial term for macroscopic multicellular algae. Algae, however, are not even plants but are protists. "Seaweed" plants would be correctly termed aquatic plants to which both vascular and non vascular aquatic plants exist.
According to the NPS, over 1100 species of vascular plants exist in Glacier NP, along with over 850 species of mosses and lichens.
Xylem exists in the vascular system of plants, primarily in the roots, stems, and leaves. It is responsible for transporting water and nutrients from the roots to the rest of the plant.
Because they contain salty soil and to support themselves.
AnatomyVascular plants contain two primary types of tube-like vascular tissues: xylem and phloem. Xylem is used to transport water and minerals from the roots upward; phloem is used to transport organic material synthesized by the plant, such as sugars, downward. These tissues are defining elements of true leaves, roots and stems, but they don't exist in non-vascular plants.TaxonomySome older classification systems include algae, certain types of seaweed, cyanobacteria and some fungi as non-vascular plants. These photosynthetic organisms are now excluded from the plant kingdom, belonging instead to Kingdom Monera, Protista or Fungi. The true plants consist of three divisions of non-vascular plants--mosses, liverworts and hornworts--and several divisions of vascular plants, including ferns, cone-bearing plants and seed-bearing plants.HabitatVascular tissues improve the efficiency of transportation of nutrients and allow plants to live in environments with limited water. Non-vascular plants were the first plants to evolve to inhabit land, and generally live in moist environments.SizeNon-vascular plants are limited in their ability to perform gas exchange and nutrient transport. This limits the plants' size, and they generally do not grow taller than 5 inches. Vascular plants, however, are not limited in size because of their ability to transport nutrients.
Pizza plants dont exist.
1.4 million plants exist on earth
What policies of sustainable development exist or could be intrduced
The plants that didnt exist in the dinosaur times were: Roses, Sunflowers and all of the plants you see now didn't exist in the dinosaur times.
Yes, trees are plants that exist.
It is estimated that there are approximately 390,000 species of plants on Earth. This number includes a wide variety of plants, ranging from tiny mosses to towering trees.
