The portion of the vein inside the ring is the wood and contains large ducts. 210. A strip of lateral meristem, cambium, is present between xylem and phloem. This stops the growth of the stem ; for its terminal bud, be- coming a blossom, can no more lengthen in the manner of a leaf-bud.

The elements are practically same, so that the two are hardly distinguishable, only the secon­dary phloem has larger elements. Beginners' botany. THE STEM—ITS GENERAL STRUCTURE 6l. BUDS AND RAMIFICATION. Monocot Leaf . Cross section of a stem: axis of a plant. They are not arranged in a continuous band, but are interrupted by chloroplast- containing parenchyma cells here and there. You can explain the central concepts associated with the six concepts. The phloem is external, i.e., it occurs towards the periphery and has the usual elements—sieve tubes, companion cells, and phloem parenchyma. It is a uniseriate zone, composed of small tightly-set cells. Xylem occurs next. This is a bilipid membrane that is made up of protein subunits and carbohydrates, with a characteristic semi permeability factor. But modern workers are of opinion that the fibres associated with the vascular bundle in sunflower stem, and as a matter of fact, in many other plants, belong to phloem. The relation between the vascular system of stem and leaf in Conifers is similar to that which obtains in Flowering Plants (cf. The vascular bundles are disposed more towards the periphery; a large parenchymatous pith is present at the central portion. The last layer of cortex is as usual the starch sheath—a wavy layer composed of barrel-shaped compactly-arranged cells with starch grains. Privacy Policy3. All the ground tissues lying inter­nal to hypodermis are composed by thin-walled parenchyma cells with profuse inter­cellular spaces. The portion outside of cam- bium ring is the bark.

The continuity of the tissues, and particularly the vascular system, has been discussed in the preceding chapter.

It is also an editable graphic with text and icon placeholders. Xylem vessels: woody part of the stem. The most important structures of plant and animal cells are shown in the diagrams below, which provide a clear illustration of how much these cells have in common. The roots absorb water and minerals from the soil and anchor the plant in the ground. These as a rule do not appear indiscriminately but at certain definite parts of the plant, viz., at the extremities of the stem IFiG. 209.

They have usually spiral and annular thickenings. Un­like most of the grasses maize stem is not hollow in the internodal region. 584). The central portion is hollow. (After Emberger).

The pericycle is quite massive, made of parenchyma (a few layers) having patches of cellulosic fibres here and there. So the sequence of tissues in the vascular bundle is outer phloem, outer cambium, xylem, inner cambium and inner phloem. The bundles re­semble those of typical monocotyledon, maize. Continuations of the pith radiate, so to say, through the regions between the vascular bundles, the so-called inter­fascicular regions, and form the primary medullary rays.
