Presence of primary root C. Presence of lateral roots D. Presence of adventitious roots Note: Indicate the name of the plant, the root system it exhibits and the parts present. Tabulate the result of your observation using the table below. Answer the related questions below. Root Characteristics Monocot Specimen (Name) Dicot Specimen (Name) Type of root system Presence of primary root Presence of lateral roots Presence of adventitious roots 1. Which root system gives better anchorage and why? 2. List down five general features of roots you can recognize in both of your specimens.Determine the collective true-false status of the statements using the choices below. I. All plant tissue arises from the activity of meristems. Meristems are analogous to stem cells in animals.; II. Primary growth arises at lateral meristems in the tips of young shoots and roots.; III. Secondary growth arises at apical meristems in older stems and roots.; IV. Vascular cambium produces secondary xylem (wood) on its inner surface, and secondary phloem on its outer surface. Cork cambium gives rise to cork, which is part of periderm. All statements are true. Only one (1) statement is true. Only two (2) statements are true. None of the statements is true.

It is important that you read each question completely before you begin. An agricultural biologist was evaluating two newly developed varieties of wheat as potential crops. In an experiment, Seedings were germinated on moist paper towels at 20°C for 48 hours. Oxygen consumption of the two-day-old seedlings was measured at different temperatures. The data are shown in the graph below. CUMULATIVE OXYGEN CONSUMPTION O Variety A 7"C - Variety A 17e O Variety B 7°C • Variety B 17°C 20 40 Time (min) 60 8. In a second experiment, variety A seedlings at both temperatures were treated with a chemical that prevents NADH from being oxidized to NAD*. Predict he most likely effect of the chemical on metabolism and oxygen consumption of the treated seedlings. Explain your prediction. v + , N - C (qu) Oxygen Consumptionemphasized how plastic and adaptable plants are in their environment. Write an essay touching on this concept. The first paragraph should be broad and discuss why plants must be more adaptable to their environment compared to other organisms, such as animals. Discuss if adaptation is or is not genetically determined and/or heritable. The second paragraph should provide a specific examples of how plants have adapted to stress. This portion needs to be in depth, and discuss both an abiotic and biotic stress.

This is a good example of the plasticity of many structures that even though they are genetically similar, the development of the structure in influenced by the localized environment of that structure. 13. Which leaf would have the greater SA:V ratio? 14. Under what environmental conditions is it advantageous to develop a thin leaf? 15. Under what environmental conditions is it advantageous to develop a thick leaf? 16. What functions of a leaf are influenced by the SA:V ratio?Plant Physiology Define or describe and give 2 functions of the plant tissue: Apical MeristemDifferentiate flowers, fruits and seeds, in terms of description, functions in plants, properties and structures.
