Want this question answered?
I really do not know, so stop buggin me!!!!
Some types of plants, known as vascular plants, have a system of vessels like circulatoy systems
ricca and marchantia are two plants without tubes they are also non-vascular
Sieve tubes are found in the phloem of Angiospermic plants.
Vascular Plants also known as Tracheophytes
Vascular plants are characterized by sieve tubes and related tissues of xylem and phloem. Previously all vascular plants were included under a common term Trachaeophyta.
Vascular Plants also known as Tracheophytes
Yes, sphagnum is a vascular plant. It belongs to a group of plants known as mosses. Mosses are non-vascular plants, but sphagnum is an exception as it has specialized conducting tissues that allow it to transport water and nutrients throughout the plant.
Vascular Plants also known as Tracheophytes
Ferns are the most commonly known seedless vascular plant, while there are also horsetails and club mosses. Liverworts are not seedless vascular plants -- they are actually nonvascular.
The vascular tissue system is one of three tissue systems that make up a plant, the other two tissue systems or ground and dermal, with dermal tissue being the outer layer and the ground tissue making up most of the inside of a plant. Vascular tissue is surrounded by ground tissue, but vascular tissue doesn't make up much of the inside of a plant, this is because vascular tissue transports water, mineral nutrient , and organic compounds, to all parts of a plant. Plants don't depend entirely on the vascular tissue system for transportation, the plants themselves can transport any necessary fluids and/or nutrients throughout their systems. A plant's vascular system is composed of two networks of hollow tubes, similar to our veins and arteries. Each network consists of a different type of vascular tissue that works to move different resources throughout the plant. These vascular tissues would be the tissues known as xylem and phloem.
