Xylem is a type of vascular tissue in plants that is responsible for transporting water and minerals from the roots to the rest of the plant. It is composed of specialized cells such as tracheids and vessel elements that provide structural support and aid in water conduction. Xylem also helps in the movement of nutrients and provides mechanical strength to the plant.
What else can I help you with?
What two properties of water are critical in moving water through xylem?
Water demonstrates adhesion and cohesionThe partial polarity of the water molecule makes it attractive to polar and less-polar surfaces.
What is a xylem in a plant and how does it work?
Xylem is a type of plant tissue that transports water and minerals from the roots to the rest of the plant. It consists of specialized cells called tracheids and vessel elements that are interconnected to form hollow tubes. As water evaporates from the leaves, it creates a suction force that pulls water up through the xylem vessels due to the cohesive and adhesive properties of water.
What are the tubes called in plants the carry water into the plant?
This is the vascular tissue xylem.
Which is a transport in a xylem plant?
The Xylem of a plant transports water and some nutrients.
Which is transported in the xylem of plant?
The Xylem of a plant transports water and some nutrients.
What two properties of water are critical in moving water through xylem?
Water demonstrates adhesion and cohesionThe partial polarity of the water molecule makes it attractive to polar and less-polar surfaces.
Describe adhesion in water?
Water has many properties, such as the properties of adhesion and cohesion. Water's adhesive property is that it wants to stick to other objects such as a table, or the inside of the xylem tube, in plants.
What direction does the xylem transport water?
The xylem in a plant transports water and dissolved minerals from the roots to the shoots and leaves. The movement of water is typically upward and against gravity due to the cohesion and adhesion properties of water molecules within the xylem vessels.
Xylem have what?
Vascular plants have xylem

What is trasported by the xylem?
Water is transported by the xylem.
What is the mechanism of water movement through the xylem?
Water is pulled upwards through the xylem by transpiration, the process where water evaporates from the leaves creating a negative pressure that draws water molecules up the plant. This cohesion-tension theory relies on the cohesive properties of water molecules and the tension created when water molecules adhere to the walls of the xylem vessels.
What are the tubes called in plants the carry water into the plant?
This is the vascular tissue xylem.
How many types of elements together make up the xylem tissue?
In Angiosperms , it is xylem vessels ( proto and meta xylem together ) , Xylem sclerenchyma and xylem parenchyma ; together form Xylem tissue ( That is why xylem is called a compound tissue ). In Gymnosperms , xylem vessels are replaced by Xylem tracheids . All other tings are almost the same .
What is the common name for secondary xylem?
primary xylem is primary in nature & is derived from procambium. But secondary xylem is secondary in nature and derived from fascicular cambium and interfascicular cambium. Primary xylem is differentiated into protoxylem and metaxylem, but secondary xylem has no such differentiation. In primary xylem vessels and tracheids are long and narrow, and vessels don't have tyloses, but in secondary xylem, vessels are blocked by tyloses, and vessels and tracheids are wider and shorter. Xylem fibres are more abundant in secondary xylem , and found in small numbers in primary xylem. Also unlike in primary xylem, secondary xylem has differentiated into sapwood & heartwood.
What are tubes that carry fluids from the roots up to leaves of vascular plants?
xylem and phloem
What are two kind of xylem and their functions?
1. Centripetal xylem 2. Centrifugal xylem both types are involved in conduction
