What benefit do plants derive from this type of specialized roots: Pneumatophores Velamen HaustoriaThis 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.In what groups and in what conditions are root hairs absent in root systems of plants?

- Why are some roots called adventitious roots? What root system best adapted for anchorage? Why do you say so? Which among the root system is most advantageous to the plant? Explain your answer.Explain why carrots, raddish and turnips are classified as roots. Why have they become fleshy?Plant B grows in unstable soil, it also needs to grow rather tall and grow quickly. This results in a tall, thin plant, grows, reproduces and dies in one year. What type of root adaptaion might it have, and what kind of life cycle would it have (use the plant terminology for life cycles)? Stolons and biennial life cycle Fiberous roots and annual life cycle O Prop roots and annual life cycle Prop roots and indeterminate growth
- Plant stem cells such as those found in cambium tissues are able to -fight microbial invaders by becoming mobile and phagocytic. -produce nutrients for other cells. -remain undifferentiated but divide to produce cells that differentiate into new tissues. -exist as mature cells.. 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.Diagram 1: Cross Section of a leaf-cells and structures. cuticle -upper epidermis palisade layer chloroplasts vascular bundle spongy mesophyll -intercellular chamber -lower epidermis stoma A possible explanation to explain the presence of the stoma structure would be that it stores extra water the leaf does not need. allows a passageway for gasses to enter and exit the leaf makes sugar needed by the cells. O maximizes the absorption of sunlight energy O O O O
