distinquish between herbaceous and woody stem?

A herbaceous stem is a soft, green stem, without any sort of bark.  A woody stem is exactly what it sounds like - a stem of a plant that has a woody external layer of cells.

this depends on the plant...different plants have VERY different requirements!

I don't think so.  For any major project like that, you need to get a permit.  Some trees are on the endangered species list, so you would have to move it instead of cutting it down.

Poppet valve would be your likely answer.\n\nCheck valve is also acceptable.

The stem of a plant is made of cellulose and lignin, tough fibers that can hold the plant up

cut the "stem" long ways and rub the inside on a burn or anything you can't store it you just cut it any time you need to use it

Meadowsweet, infusion.\nFennel seed, infusion.\nIceland moss, infusion.\nany one of the three will help your problem.

1st to answer, yes, both are gymnosperms

None.It grows that way.On trees of course.lol

(if you need this for homework, please rewrite it in a coherent way!)\nThe plants that live in xeric (=dry) environments are called xerophytes and have many adaptations that help reduce water loss. Basically these include mechanisms for 1) reducing body surface (because evaporation/transpiration is directly proportional to body surface) and 2) reinforcing their "skin" to make it less permeable.\n\nAdaptations tending to 1) include:\n- Small and thick or absent leaves, may be transformed into spines; they photosinthesize with their stems (such as cacti)\n- Short, stumpy shape; rounded stems.\n\nAdaptations tending to 2) include:\n- Leaves with multilayered epidermis and a thick waxy cover (waterproof)\n- Leaves may be covered with hairs.\n- Small stomata, situated in recessed crypts\n- Some have the stomata open only during the nighttime (CAM metabolism)

Grafting is a method of plant propagation widely used in horticulture, where the tissues of one plant are encouraged to fuse with those of another. It is most commonly used for the propagation of trees and shrubs grown commercially. (Grafting is limited to dicots and gymnosperms. Monocots lack the vascular cambium required.)\n\nIn most cases, one plant is selected for its roots, and this is called the stock or rootstock. The other plant is selected for its stems, leaves, flowers, or fruits and is called the scion.\n\nIn stem grafting, a common grafting method, a shoot of a selected, desired plant cultivar is grafted onto the stock of another type. In another common form called budding, a dormant side bud is grafted on the stem of another stock plant, and when it has fused successfully, it is encouraged to grow by cutting out the stem above the new bud.\n\nFor successful grafting to take place, the vascular cambium tissues of the stock and scion plants must be placed in contact with each other. Both tissues must be kept alive till the graft has taken, usually a period of a few weeks. Successful grafting only requires that a vascular connection takes place between the two tissues. A physical weak point often still occurs at the graft, because the structural tissue of the two distinct plants, such as wood may not fuse.

Answers provided so far a basically correct except they have the primary functions of xylem and phloem reversed. See links below.

I will guess that you intended to smother the plant (prevent it from breathing) by covering the undersides of the leaves.  While it is true in many plants that there are more stomata (breathing holes) on the undersides of leaves, there are also stomata on the tops of leaves.  Perhaps there are enough stomata on the top of the leaf to allow the plant to continue to live...or to last longer (and slowly die) compared with what you expected.

no ... bamboo is classed as a GRASS, not a tree. Deciduous trees loose their leaves in autumn/fall.

I'm not really sure what they are looking for.  There are many different results that can occur.  It also depends on how much of the plant is cut and removed, when in the plants life cycle you make the cut, which part of the plant you cut off, etc.  I would guess that they are looking for a difference in vertical shoot growth.  If the apical (the top of the main stem) meristem is removed this will cause lots of lateral growth and branching.  This happes because the auxin hormone is no longer able to go to the apical meristem so it it activates lateral bud growth.  Another thing that might happen depending on plant type is that you might get sucker growth.  This happens when too much of the photosynthetic material is removed.  The roots then start to send up suckers which are new stems growing off of the existing root system.  This is most common in trees and will only happen in woody plants.
