What else can I help you with?
What is the outer layer of growing tissue that surrounds the expanding phloem tissue in trees?
Xylem
Which of the following describes a process of succession after a forest fire?
It depends on where the fire occurs, and what kind of habitat is present. In general, most often, grasses and forbs will become reestablished first, followed within a couple years by the return of sapling trees and woody plants. Over many decades, fast-growing trees will become reestablished first, then eventually give way to old-growth forest types of trees.
What makes water to rise in tall trees several meters high?
diffusion .pull of the vascular tissues the phloem and xylem.hope woudn't help.
Where does height growth and cell division occur in tree growth?
Height growth occurs in the apical meristem. Radial growth occurs at the cambium layer. Cells divide into phloem and xylem. Phloem cells become the bark. Xylem cells become wood. In the early season the cells are larger, as the season goes on and water, light, and nutrients diminish the cells become thicker walled and smaller. The different sizes are termed spring and summer wood and these are the rings that you can count to determine the trees age.
What purpose does vascular tissue serve in trees?
Vascular tissue in trees, composed of xylem and phloem, facilitates water and nutrient transport throughout the tree. Xylem transports water and minerals from the roots to the leaves, while phloem transports sugars produced in the leaves to other parts of the tree. In essence, vascular tissue is crucial for the tree's growth and overall function.
Leaves dont have secondary xylem and phloem why not?
Leaves are designed to last only a short time so a secondary xylem and phloem supply is not needed. These chemicals offer a strong support system that is not needed in the leaves, just the trees.
What tissues arise from the active cell division of the vascular cambium?
The vascular cambium undergoes active cell division to produce secondary xylem (wood) towards the inside of the stem and secondary phloem towards the outside. This results in the growth of woody tissues in trees and other woody plants.
What will happen if a tornado uproots most of the trees in an ecosystem?
If a tornado uproots most of the trees in an area, then secondary succession will occur. In secondary succession, the vegetation itself or much of it has been destroyed, but the soil and seeds remain in place. Plants will grow from these seeds. Eventually new trees will grow and, after a few decades, the area will have returned to normal.
Are pine trees vascular or nonvascular?
Pine trees are vascular plants because these have well defined xylem and phloem tissues.
What is the outer layer of growing tissue that surrounds the expanding phloem tissue in trees?
Xylem
The dissolved sugars produced in the leaves of a maple tree move to the trees roots through the?
phloem
Is a pond a renewable or a non renewable resource?
i have never known of using frogs as a fuel or some similar purpose
Why are trees classified as vascular plants?
because trees have areas that transport nurtients and water from the soil below it. The phloem and xylem contribute to the spread of these essential nutrients.
What do you get from trees directly?
The main direct products of trees are fruit and wood. There are many secondary benefits also.
Do trees die?
Every 'living' thing will die eventually, that includes trees.

Example of phloem?
Phloem is a type of plant tissue responsible for transporting organic nutrients, mainly sugars, produced during photosynthesis, from the leaves to other parts of the plant, such as the roots and fruits. It consists of sieve tubes, companion cells, fibers, and parenchyma cells. One common example of phloem in plants is the phloem bundles found in vascular bundles within the stems of plants like trees.
