Concept explainers
To explain: The agricultural value of research to understand the control of root hair development.
Introduction: Roots and stems of plants are produced with secondary growth. Gymnosperms and woody eudicots have primary growth at apical meristem and at lateral meristem, the secondary growth occurs. The secondary tissue is produced as a result of the activity of two lateral meristems, namely the cork cambium and vascular cambium.
To explain: The agricultural value of the interactions leading to the mycorrhizal association.

- Compare the leaf structure of Nerium to Ligustrum. Look for stomata. Where are they located? On the upper or lower leaf surface? How is the surface of the leaf modified? Can you recognize why these leaves are said to have “sunken stomata”? Look for “hairs” on the leaf surface. Where are they located? How are they advantageous? How does the appearance of each tissue layer in Nerium differ from Ligustrum? Compare the upper epidermis to the lower epidermis. Compare the amount of cuticle.arrow_forwardIs rooting preferred to regenerate first or shooting and why? (Subject: tissue and cell culture)arrow_forward. Compare the leaf structure of Potamogeton to Ligustrum. Look for stomata. Where are they located? On the upper or lower leaf surface? Does Potamogeton have sunken stomata or leaf hairs? Look at the area beneath the upper epidermis and compare it to the Ligustrum and Nerium leaves. How does it differ? What value does this have for the plant? How does the appearance of each tissue layer in Potamogeton differ from Ligustrum? Compare the upper epidermis to the lower epidermis. Compare the amount of cuticle. Compare the organization of the mesophyll cells to those in Ligustrum.arrow_forward
- As shown. What are the four diffusion paths that a molecule might follow as it travels through the root epidermis and cortex? Why does this diagram stop at the endodermis? What happens at the endodermis?arrow_forwardWhich of the following pathways best summarizes the route of a mineral that isabsorbed by a plant? a. Root hairs → epidermis → cortex → endodermis → pericycle → xylem b. Root hairs → epidermis → endodermis → cortex → xylem c. Root hairs → pericycle → endodermis → cortex → xylem d. Root hairs → endodermis → cortex → pericycle → xylemarrow_forwardHow is the mycorrhizal association helpful in absorption of water and minerals in plants?arrow_forward
- Shooting is preferred to regenerate first than rooting. Why?arrow_forwardExamine the roots of Vanda Sp. Cut across one root with sharp razor blade and observe closely. Use a dissecting microscope or hand lens. Identify and describe this tissue? Is there any special function of this tissue?arrow_forwardWhat structural features of guard cells foster their ability to form anopen pore in plant epidermal surfaces?a. thickened inner cell walls and radially oriented microfibrilsb. thickened outer cell walls and radially oriented microfibrilsc. thickened inner cell walls and longitudinal microfibrilsd. thickened outer cell walls and longitudinal microfibrilse. uniform thickness of cell walls and randomly arrangedmicrofibrilsarrow_forward
- Observe the root system of a plant with root nodules. If you don’t have these plants at home or at your backyard, you may look up for their pictures in any references. Draw the root system and describe the nodules by noting the location, nature of attachment, shape, and their relative sizes.arrow_forwardThis is about vegetative organs in Botany course. In what groups and in what conditions are root hairs absent in root systems of plants? Why are root hairs not formed at the region of elongation and after the region of maturation? Briefly explain why growth in plants is said to be indeterminate. Is there a significance of compound leaves relative to strong winds? How about leaf-eating animals? Justify your answer.arrow_forwardGinger undergoes three (3) stages of Growth. Name and describe the these stages from Germinating stage to time for harvestingarrow_forward
