Solved in 2 steps
- Discuss the leaf epinastic movement of monggo (Vigna radiata) seeds within five days of seed germination.explain the roles of plant hormones in seed dormancy, seed germination, and directional growth of the emerging root and shoot?What major factor controls the photomorphoses of germinated seeds? Explain briefly its role.
- Examine the shoot system of a mature plant (Coleus blumei). Identify the shoot tip, nodes, internodes, leaves, and axillary buds. Each unit of stem that consists of a leaf, axillary bud and internode is referred to as a phytomere. Note that axillary buds always occur above a leaf. Axillary buds give rise to branch shoots. Thus, branching in a shoot system is exogenous (of external origin). How does this compare to branching in a root system?Describe the differences between eudicot and monocotseed germination.Discuss the transport of water from roots to leaves and a particular tropism/nastic movement in Rosa damascena
- Discuss the factors responsible for ascent of xylem sap in plants.The oat coleoptiles of the seedlings above have been modified: either cut or placed in a light-blocking tube. Which ones will stills bend toward a directional light source?Describe seed germination. Investigate conditions necessary for seed germination. Define seed dispersal. Describe the different modes of seed dispersal. Identify seeds and fruits according to their modes of dispersal.
- Green mangoes were freshly harvested from tree and buried in a jar of uncooked rice to accelerate ripening process. During storage, the fruit colour has changed to yellow. Explain the principles behind this ripening process by relating to the fruit tvne and identify the phytohormone responsible for this ripening process. (i) Suggest another simple method to expedite the ripening process with another fruit of the same type. Marks will be awarded for the correct type of materials (fruit), method and experimental set up (temperature and space). (ii)Explain: Internally, cycad stems are similar to those of seed ferns— a thick cortex containing secretory ducts surrounds a small amount of manoxylic (parenchymatous) wood.Discuss other morphological differences between sunny and shady set-ups of mung bean in relation to phototropic response of plants.
