Explain 2 primary functions of plant roots.
Also provide one example of a modified root and explain why the modification has been selected for evolutionarily (what advantage does it provide?)
Step by step
Solved in 3 steps
- Explain 2 primary functions of plant stems. Also provide one example of a modified stem and explain why the modification has been selected for evolutionarily (what advantage does it provide?)Root hairs greatly increase the root’s surface area. In rye, a single plant has been found to have __________________ lateral roots with ________________ km of root length and a surface area of _________________ m2. Convert the length to miles (1 mile = 1.6 km) and the area to square feet (1 foot = 0.3 m).Observe the image of roots/roots system of Zea mays Are there special features that you observe? What do you call the root present above the ground? How does this root differ from the other types of root system? Are there any special function(s) of this type?
- from the viewpoint of the plant, can you suggest a practical reason for branch roots originate internally instead of at the surface?1. Why is that the wall of epidermis in the root area have no cuticle and have thin walls? 2. What is the importance of the ability of a plant to form adventitious roots? Relate this to the plant’s characteristic of being an immobile organism.From the viewpoint of the plant, can you suggest a practical reason for branch roots originating internally instead of at the surface?
- 1. This type of specialized roots is characterized by contorted xylary elements and collapsed cortex. 2. The region of the root that is highly specialized for storage of substance.Describe the unique features of the following specialized roots in plants. What benefit do plants derive from this type of specialized roots - Mycorrhizae - Root nodulesWhy 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.
- 2. Name 2 examples of adaptative variations of aerial stems and give their functionsDescribe the unique features of the following specialized roots in plants. What benefit do plants derive from this type of specialized roots: Pneumatophores Velamen HaustoriaThe buds of certain plants occupy a definite position within the soil or on itssurface. This position is mostly obtained by the pull of special roots, which have been termed contractile roots. Such roots exist in many herbaceousdicotyledons. Identify this type of modified root.
