Does each cell of a vascular plant have to absorb water from the environment?
no
What is the path that water takes through the starfishes vascular system?
it has many lateral poles witch branch off into each radial canal at the end of the tube feet. the tube feet an animal move
How are cephalopod nervous systems unique among mollusks?
Well what I know about this question is that..............Cephalopods nervous system is like this all echinoderms have a simple nervous system similar to that of a jellyfish. Around the mouth is a circle of nerve fibers called the nerve ring. In sea stars, a radial nerveruns from the nerve ring to the tip of each arm.The radial nerves control the movements of the sea star's arms.One characteristic that is unique to echinoderms is the water vascular system. The water vascular system is a system of canals filled with fluid. It uses water pumps to help the animal move, eat, breathe, and sense its environment.The water vascular system of a sea star. Notice how water pressure from the system is used for many functions.
How are circulatory and vascular system different from each other?
they are different because the circulatory system transport blood to the cells and the blood also gives other resoures to the cells and the vascular system is when it pumps blood in your vessels.
What are the bulb-like sacs in echinoderms that push water through canals as a part of their vascular system?
The structure in an echinoderm that is a bulb like sac and pushes what is called the ampulla. It is connected to the radial canal of the water-vascular system. Each ampulla controls tube feet. The tube feet can extend when water pressure is increased by the ampulla being squeezed. :)
What is vascular tissue?
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.
What is vascular plant and nonvascular plant?
Vascular plants are plants that have transport tissues for carrying water, nutrients, and sugar to plant cells. Because they have transport tissues, many vascular plants can become very large. An example of a vascular plant is a full grown tree. The transport tissues form a system of tubes tat extends from the roots to all parts of the plant. These tubes are made up of two kinds of tissue: xylem and phloem. Xylem tissue carries water and nutrients from the roots to the leaves. Phloem tissue carries sugar from the leaves to other cells of the plants. Non vascular plants are plants that lack tissues that transport water, nutrients, and sugar. Some example of non vascular plants are mosses, liverworts, and hornworts. Non vascular plants don't have tissues to carry the materials that cells need to stay healthy. Because of this, they don't grow very large. These plants don't have true roots to absorb water. Instead, each cell absorbs the water and nutrients it needs directly from the soil or air. Because they tend to live very close together, the cells of these plants may also get materials they need from neighboring plant cells.

A narrow strip of water that extends into a coast?
yes they did and they still love each other at this very minuite / other words TOTALLY!!
What does non nonvascular mean?
Non-vascular plants is a general term for those plants without a vascular system (xylem and phloem). Although non-vascular plants lack these particular tissues, a number of non-vascular plants possess tissues specialized for internal transport of water. Non-vascular plants have no roots, stems, or leaves, since each of these structures is defined as containing vascular tissue. The lobes (rounded parts) of the liverwort may look like leaves, but they are not true leaves because they have no xylem or phloem. Likewise, mosses and algae have no such tissues. All plants have a life cycle with an alternation of generations between a diploid sporophyte and a haploid gametophyte, but nonvascular plants include the only plants that have a dominant gametophyte generation. In these plants, the sporophytes grow attached and are dependent on gametophytes for taking in water and other materials. Non-vascular plants grow from spores.
How does the water vascular system help a starfish move around?
The water vascular system of a starfish helps it move around by creating hydraulic pressure that powers the tube feet. These tube feet are connected to canals that run throughout the body of the starfish, allowing it to extend and contract them. By controlling the amount of water in the tube feet, the starfish can use them to grip and push off surfaces, enabling movement.
How does an echinoderm move?
Echinoderms, brittle stars, sea urchins, sand dollars, sea lilies, feather stars, and sea cucumbers, are globally distributed in almost all depths, latitudes and environments in the ocean. Almost all echinoderms are benthic - that is, they live on the sea floor-some can swim, and a few deep-sea sea cucumbers are fully floating. Some attach to floating logs and debris, but echinoderms mostly stay in one place. Sea starts inch along on psuedopods, or tiny bulb-like feet.Echinoderms have a water vascular system instead of a circulatory system. This water vascular system is used for gas exchange, feeding, and locomotion. Echinoderms have tube feet called podia with suction pads situated at their extremities. This vascular system force water through canals of small muscular tubes to the tube feet located in a groove on the underside of each are called the ambulacral groove. As the tube feet press against a moving object, water is withdrawn from them, resulting in a suction effect. When water returns to the canals, suction is released. The resulting movement is generally very slow.All echinoderms have tube feet. These feet have suction disks that enable the animals to crawl or attach themselves to objects.
