THE centripetal xylem in the stem among the vascular plants is confined to the Pteridophyta and lower gymnosperms, the Pteridospermæ and the Cordaitales. The vegetative stem of Cycadales and Coniferales lacks centripetal xylem; but it occurs in a poorly developed condition in certain conservative regions like the reproductive axes and the leaf traces. In the Gnetales and the angiosperms the axial organs show exclusively the endarch condition, and the centripetal xylem is altogether absent from the primary vascular bundles.
What else can I help you with?
What are the two kinds of xylem and their functions?
The two types of xylem are tracheids and vessel elements. Tracheids are elongated cells that transport water and minerals vertically within the plant. Vessel elements are shorter and wider cells that are more efficient at water transport but are less structurally supportive.
What are the tubes called in plants the carry water into the plant?
This is the vascular tissue xylem.
What is a sentence for centripetal?
If you mean centripetal force, I was surprised when I saw that the water was not spilled when it was swung around in a circle, but then I learned that centripetal force kept it inside.
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 are two kind of xylem and their functions?
1. Centripetal xylem 2. Centrifugal xylem both types are involved in conduction
What are the two kinds of xylem and their functions?

What keeps an object in centripetal motion?
The centripetal force
The word means center-seeking?
centripetal
How does the centripetal force affect the centripetal acceleration of an object moving in a circle?
The centripetal force is responsible for providing the centripetal acceleration required to keep an object moving in a circle. As the centripetal force increases, the centripetal acceleration also increases, causing the object to move in a tighter circle. Conversely, a decrease in centripetal force will lead to a decrease in centripetal acceleration, resulting in a wider circle or the object moving off its circular path.
Xylem have what?
Vascular plants have xylem
What is the symbol for centripetal force?
The symbol for centripetal force is "Fc".
What is trasported by the xylem?
Water is transported by the xylem.
What is the definition of Centripetal?
"Center-seeking" or "directed to the center" is the definition of centripetal.
How does centripetal force affect centripetal force?
Centripetal acceleration is proportional to the square of the speed (a = v2/r). Therefore, according to Newton's Second Law, centripetal force is also proportional to the square of the speed.
What are the tubes called in plants the carry water into the plant?
This is the vascular tissue xylem.
What is a sentence using the word centripetal?
A ball on a string is an example of centripetal acceleration
