Vascular bundles may be radial or conjoint depending on the position of xylem and phloem. They may be open or closed depending on the presence or absence of cambium between their xylem and phloem. They may be scattered or arranged in a ring.
Trees have two types of growth: primary growth and secondary growth. · Primary growth occurs at the tips of roots and stems and results in their growing taller or longer. · Secondary growth takes place in the vascular cambium and the cork cambium and results in an increase in the diameter of the stem or trunk of the tree. Cambium lies between the old wood and the bark of the tree. The vascular cambium is a thin layer cells that produces conducting cells - xylem and phloem. · The phloem is the outer layer, and is sometimes referred to as the inner bark. It is a food conducting tissue. The xylem is located toward the inside of the cambium layer. · The xylem is the vascular tissue through which most of the water and minerals of the tree are conducted. More secondary xylem (added toward the inside of the cambium layer) than secondary phloem (added toward the outside of the cambium layer) is produced by the cambium. The definition of wood is secondary xylem, reflected by the origin of the term 'xylem', the Greek word xylon, for wood. Another layer, the cork cambium, contributes to the expanding girth of a tree. The cork cambium is a thin layer cells that ultimately produces the bark of the tree. The bark is composed of several types of tissue produced (both toward the inside and the outside of the tree) by the cork cambium layer.
Xylem is composed of tracheary elements (such as vessels and tracheids) and fibers. Phloem is composed of sieve tube elements and companion cells.
The vascular cambium adds to secondary xylem and secondary phloem while the cork cambium gives rise to cork and secondary cortex. The vascular cambium is a remnant of the apical meristem while the cork cambium is a true secondary meristem which develops outside the vascular tissues.
Two different types of fruits are citrus fruits (e.g. oranges, lemons) and berries (e.g. strawberries, blueberries).
Two types of secondary meristems are the vascular cambium and the cork cambium. The vascular cambium is responsible for producing secondary xylem (wood) and secondary phloem, contributing to the growth in thickness of stems and roots. The cork cambium generates cork cells, which replace the epidermis and provide protection to the plant. Both types of meristems play crucial roles in the secondary growth of dicotyledonous plants.
Between the primary xylem and the primary phloem.
Two types. By saying there are two 'types' you are already stating that there are 2 differentthings and so the word 'different' isn't necessary.
Cambium is not a country.
there two different types of Heart disease
Cork cambium is used for secondary growth.Cork cambium produces new dermal tissues that replace the epidermal tissues from protoderm. Cork cambium is consisted of cork cambium and cork.
They are bark, phloem, cambium, and xylem.
Vascular bundles may be radial or conjoint depending on the position of xylem and phloem. They may be open or closed depending on the presence or absence of cambium between their xylem and phloem. They may be scattered or arranged in a ring.
cambium
There r two different types
vascular cambium produces secondary phloes and secondary xylem. interfascicular cambium are been between vascular bundles in near stems.
The two kinds of meristems are apical meristem, located at the tips of roots and shoots, responsible for primary growth, and lateral meristem, found in the vascular cambium and cork cambium, responsible for secondary growth in plants.
