cambium தமிழ் அர்த்தத்தின் உதாரணம்:

சூட்புறத்தில் நீரைக்கொண்டுபோகும் சைலம் என்னும் உட்குழாய்த் திசுவும், வெளிப்புறத்தில் உணவைக் கொண்டுபோகும் புளோயம் என்னும் சல்லடைக் குழாய்த் திசுவும், இரண்டுக்கும் இடையே காம்பியம் என்னும் வளர்படைத் திசுவும் இருக்கும்.

cambium's Usage Examples:

cambium layer A thin layer of specialized cells which lies between the inner bark and the sapwood.

In stems with open bundles the formation of cambium and secondary tissue may be confined to these, when it is sard to be entirely fascicular.

In favourable cases remains of the cambium are found on the outer border of the wood, and phloem is also present in the normal position, though it does not seem to have attained any considerable thickness.

Opposite the primary xylems, the cambium either (a) forms parenchyma on both sides, making a broad, secondary (principal) ray, which interrupts the vascular ring and is divided at its inner extremity by the islet of primary xylem; or (b) forms secondary xylem and phloem in the ordinary way, completing the vascular ring.

In such stems and roots as increase in thickness there are other growing regions, which consist of cylindrical sheaths known as cambium layers or phellogens.

The activity of the new cambium is often associated with the stoppage of the original one.

The primary structure f ` is only found unaltered in the 1 1, 1 ` by means of a cambium set in very Il 111/1/1, 1 1 early, xylem being formed internally and phloem externally in a perfectly normal manner.

Sometimes the activity of the successive cambiums simply results in the formation of concentric rings or arcs of secondary xylem and phloem.

Any clean cut, fracture or bruise which injures the cambium over a limited area is met with the same response.

Wood thus altered is known as heart-wood, or duramen, as distinguished from the young sap-wood, or alburnum, which, forming a cylinder next the cambium, remains alive and carries on the active functions of the xylem, particularly the conduction of water.

bundles of plants which form cambium are, on the contrary, called open.

The arrangement of the conducting tissue in the stem is characteristic; a transverse section of the very young stem shows a nunber of distinct conducting strands - vascular bundles - arranged in a ring round the pith; these soon become united to form a closed ring of bast and wood, separated by a layer of formative tissue (cambium).
