Summary Introduction
Introduction: In plants, the growth occurs throughout their life. This is so, because in plants there is presence of meristems. These meristematic cells divide continuously and lead to the formation of new cells, which are further elongated and differentiated.

Students have asked these similar questions
Why is the secondary xylem and phloem always to either side of the vascular cambium and is the primary xylem pushed inwardly by the secondary tissues? How about the primary phloem, cortex and epidermis, are they pushed outward by the secondary tissues?
Why does a layer of periderm offer only temporary protection? When the plant makes a new layer of cork cambium, does it make the new layer to the outer side of the failing periderm or to the inner side of it, deeper in thesecondary phloem?
Because secondary phloem is formed from the vascular cambium just as secondary xylem is, it too has an __________________________ system and a _____________________ system. Why do the size, shape, and number of phloem rays match those of xylem rays?

- Why is the secondary xylem and phloem always to either side of the vascular cambium?arrow_forwardRanunculus root (Root anatomy) Explain the functions of each of the tissues in the root (primary xylem, primary pollen, cortex, epidermis). What are the similarities and differences between the anatomy of the root vs that of the stem?arrow_forwardAside from conducting water and minerals, what is another important function of secondary xylem?arrow_forward
- In comparison with stems, roots secondary xylem exhibits..... 1. wider vessels 2. primary xylem outside of the secondary xylem 3. greater lignification 4. more derived parenchyma cells 5. less amount of parenchymaarrow_forwardFrom the viewpoint of the plant, can you suggest a practical reason for branch roots originating internally instead of at the surface?arrow_forwardThe mature regions of roots are relatively impermeable to water. Why? Explain its importance.arrow_forward
- Given that (a) xylem is located toward the upper epidermis in leaf veins and phloem is located toward the lower epidermis and (b) the vascular tissue of a leaf is continuous with that of the stem, suggest one possible arrangement of vascular tissues in the stem that might account for the arrangement of vascular tissue in the leaf.arrow_forwardWhat morphological and anatomical features of the roots make them efficient organs for anchorage and absorption? Explain.arrow_forwardWhich of the following statements are true of xylem? A) It is found in all land plants.B) It assists in conducting of materials, such as water and minerals, throughout the plant.C) It can provide structural support to the plant.D) It is found in the gametophyte generation, but not in the sporophyte.E) It contains specialized cells known as tracheids and vessel elementsarrow_forward
- Which of the following statements are true for root endodermis?I. Endodermal cells constitute the innermost layer of root cortex and surrond the vascular cylinder (xylem and phloem). II. Endodermal wall is covered with waxy layer of casparian strip which blocks apoplastic transfer of minerals.III. Due to presence of casparian strip, water and minerals can only eneter the vascular cylinder if they will be able to cross the plasma membrane of an endodermal cell.arrow_forwardIn a cross-section of a tree, where are the oldest growth rings—in the outer region or nearer the pith? Where is the oldest secondary phloem—near the outside of the tree or near the cambium?arrow_forwardHow does the vascular cambium give rise to xylem? By lignifying cortex cells By generating new cells to the outside of the cambium By generating new cells to the inside of the cambium By lignifying pith cellsarrow_forward
