Concept explainers
To sketch: Side by side two daughter cells formed after mitosis of a meristematic cell in the vascular cambium of a eudicot stem and label the cell formed toward the interior of the stem a meristematic cell.
Introduction: Vascular bundle is a part of transport system in vascular plants. Xylem and phloem are the two tissues present in the vascular bundles. In addition to this, supporting and protective tissues are also present in the vascular tissue. The vascular tissues in the stems are called vascular bundle and the vascular tissue in the roots are called vascular cylinder. The vascular tissue structure varies in both
To determine: Whether the daughter cell formed toward the outside should be labeled primary xylem, primary phloem, secondary xylem, or secondary phloem.

The vascular tissues in the stems are called vascular bundle and the vascular tissue in the roots are called vascular cylinder. The vascular tissue structure varies in both monocot and eudicot plants.

- Can you answer this diagram pleasearrow_forwardObserve the following photos of the shoot of a monocot (left) and an eudicot (right). How are these shoots similar? How do they differ in terms of the appearance (morphology) of the leaves and the way the leaves are attached?arrow_forwardMake a labelled line diagram of the cross section of the leaf with the following labels: cuticle, adaxial epidermis, abaxial epidermis, primary xylem, primary phloem, collenchyma, bundle sheath, vascular cambium, stomata, mesophyll that consist of palisade and spongy parenchyma with intercellular spaces.arrow_forward
- Match the following plant cells and tissues with their definition: - v Collenchyma A. grouped in strands and help support young parts of the plant shoot. They have unevenly thickened primary cell walls. - v Sugar-conducting cells of the phloem B. are alive at maturity, but lack organelles. Each sieve-tube element is connected to a companion cell by plasmodesmata. Water-conducting cells of the xyleem v Sclerenchyma C. The two types of water-conducting cells, tracheids and vessel elements, are dead and lignified at maturity. - v Parenchyma D. rigid due to thick secondary walls containing lignin, dead at functional maturity and play a role in support in the plant. E. cells are flexible and provide the most diversity of functions (such as photosynthesis)arrow_forwardCompare the stem of a monocot, dicot, and woody dicot: Feature Monocot Herbaceous dicot Young woody dicot Cortex (+/-) Specific supporting structures or tissues (+/-) Vascular bundle arrangement Vascular cambium (+/-) Pith (+/-)arrow_forwardMatch each cell type with its correct description.arrow_forward
- 6) Match the tissue on the left with the description of the function it generally performs for the plant on the right: a) phloem flexible support, such as in petioles and herbaceous stems. b) xylem forms an outer barrier for leaves, young stems and roots. c) collenchyma conducts water and dissolved nutrients from the roots to other plant tissues. support of vascular tissue in older woody plants and formation of very hard plant structures such as nut shells. d) periderm e) parenchyma metabolism and storage. f) sclerenchyma conducts molecules produced by the plant throughout the plant body. g) epidermis provides physical protection for woody plants. AP ACMIarrow_forwardExamine an image of longitudinal section through a Coleus stem tip. Draw the apical meristem, leaf primordia (developing leaf), bud primordia (developing axillary buds), nodes, and internodes. How many phytomeres are present in this preparation? Beginning with the apical meristem, follow the development of shoot tissues. Label protoderm, procambium, and ground meristem, pith, and cortex. You will not be able to identify any mature cells or tissues in this slide (keep in mind the size of the shoot tip).What are the mature tissues that each of these primary meristems become?arrow_forwardThe cross-section of a woody root is shown in Figure 3. Observe and locate the center of the root and work to the outer portion. Identify and label the following: Secondary phloem Secondary xylem Primary xylem Vascular cambium Xylem rayarrow_forward
- Figure 2 shows the cross-section of a eudicot root. i. Based on Figure 2, identify the structure that regulates the movement of water and minerals towards the xylem in the root. ii. Name structure of the cell membrane allows it to act as a selective barrier? iii. Predict what will happen to the transportation of water and minerals through the plasma membrane if the root was poisoned and no cellular respiration occurredarrow_forwardSketch observations of monocot stem cross section and the dicot stem cross section. Label the epidermis, phloem, xylem, cortex, and pith or ground tissuearrow_forwardPlant Physiology Define or describe a Xylem tissue.arrow_forward
