- 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?)Explain 2 primary functions of plant leaves. Also provide one example of a modified leaf and explain why the modification has been selected for evolutionarily (what advantage does it provide?)B. LEAF ADAPTATION The main function of the leaf is in the processes of photosynthesis and transpiration. Apart from these functions, leaf is sometimes adapted to perform other functions. Examples of leaf adaptations are for: a) Support, which could be seen by the presence of tendrils b) Catching insects, by having cup-liked shape of hairs sensitive to touch c) Reproduction, by having meristematic cells able to produce new shoots that will go on to become new individual plants d) Food and water storage, especially found in plants living in dry areas where water is scarce (for example succulent plants, having leaf storing food and water) e) Floatation, for plants living on the water surface, their leaves in general will have air openings on tissues (used for floating) usually found on leaf petiole f) Protection, by having leaves completely or partially modified as thorns Instruction: a) 1. Search for ONE plant species with the following leaf adaptations 2. Give their scientific names…
- I. Look for representative specimens of herbaceous dicot and monocot stem. The external parts that can be observed are nodes, internodes, leaf scar, lenticel, and buds (axillary and terminal). Examine and compare their external morphology by answering the questions below: 1.. What is the function of the lenticels? Do all stems have lenticels? 2. How can you differentiate a monocot plant from a dicot plant just by looking at the stem? 3. What advantage would herbaceous stems have over woody stems? 4. What advantage would woody stems have over herbaceous stems? II. Compare the internal anatomy of stems of xerophytes, mesophytes, and hydrophytes. Relate differences to the nature/habit of the different plants.1. Identify the labeled cells, tissues and other associated structures. В A P Q A (region) CI C2 S D T E F V W H X Y J Z K A1 C1 (basic and subtype) L A2 M. N АЗ A4 C2 (term for xylem arms) 2. Discuss which pathway permits the passage of most solutes and water inside the roots? Which pathway allows the entry of most of the water and some of the solutes inside the root tissue? Explain how the Casparian strip creates a barrier for substance moving through this pathway and how it is circumvented. D (tissue composition) E (single layer of cells) L (red cellular coating) H (conducting tissue) G (give rise to lateral roots) O (function) K (conducting cell) J (уре of maturation) M I (conducting cell) (specific cell) F (conducting tissue) N (name of plant specimen )What do you mean by "modification of roots"? Describe some of the modifications of tap roots giving suitable examples.
- The 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.Describe the unique features of the following specialized roots in plants. What benefit do plants derive from this type of specialized roots: Pneumatophores Velamen HaustoriaFrom the viewpoint of the plant, can you suggest a practical reason for branch roots originating internally instead of at the surface?
- from the viewpoint of the plant, can you suggest a practical reason for branch roots originate internally instead of at the surface?Kindly provide 2 examples plants having "adaptations for twining" including (i) mechanical support (ii) transportation for root materials (iii) production of new plants Kindly sketch the diagramDescribe the unique features of the following specialized roots in plants. What benefit do plants derive from this type of specialized roots - Mycorrhizae - Root nodules
