1. Like other plants, Venus Flytraps gather nutrients from the soil. However, they live in poor soil and are healthier if they get nutrients from insects. Once an insect lands in the “mouth” of a Venus Flytrap, the trap closes and is flooded with digestive enzymes similar to those in your stomach. These enzymes break down the insect. These digestive enzymes could be classified as which biomolecule? A. Carbohydrates B. Proteins C. Lipid D. Nucleic Acids 2. Cells can generate as many as 36 to 38 molecules of adenosine triphosphate (ATP) from the metabolism of one molecule of glucose. Which cellular process results in this amount of ATP production? A. B. C. D. Cellular respiration Protein synthesis Lysogenic cycle Photosynthesis 3. Most plant leaves take in more carbon dioxide as light increases. They give off carbon dioxide if light intensity is too low. The graph shows a plant’s carbon dioxide levels at different light intensities. At point X, the rate of which process is equal to the rate of photosynthesis? A. B. C. D. Cellular respiration Transpiration Growth Reproduction 4. Meristematic tissues in plants are composed of cells specialized for cell division (mitosis). These types of cells are most likely to be found in what part of the plant? A. B. C. D. Leaf epidermis Stem tips Root tips Both b and c 5. Many vegetables (ex. Carrots and beets) store glucose made during photosynthesis. Since this type of storage is underground, they are unable to photosynthesize. When glucose is transported to the site of storage by phloem, which two systems are working together? A. B. C. D. Root and reproductive Root and vascular Vascular and reproductive Muscular and vascular 6. The exchange of oxygen and carbon dioxide occurs on the leaves of plants. The carbon dioxide is used to help harness energy from the sun. Plants use the energy for many functions. One of which is the production of flowers. When a plant’s phloem transports glucose to the site of flower production, the reproductive system is working primarily with A. B. C. D. The root system The vascular system The immune system The muscular system 7. Copper is a micronutrient that can be found in soil. Copper is important for reproductive growth in plants and plays an indirect role in chlorophyll production. Which statement correctly describes the interaction that occurs between the root and the shoot systems of plants to allow reproduction to occur? A. Copper is produced in the roots when copper-containing compounds are hydrolyzed. B. Copper that is absorbed by the roots is transported to reproductive tissues by the shoot system. C. The shoot system stores copper for later use by the roots and the reproductive structures. D. The shoot system transports copper to the roots after it is taken in through stomata in the leaves 8. In most plants roots grow downward while stems grow upward. Which of the following represents the correct structure associated with the correct tropism? A. Roots: Gravitropism & Hydrotropism Stems: Gravitropism & Phototropism B. Roots: Phototropism Stems: Thigmotropism C. Roots: Gravitropism & Phototropism Stems: Gravitropism & Hydrotropism D. None of the above 9. Structures represented in the illustration below are found in the lower epidermis of a plant leaf. The illustration at right shows the response to a certain environmental condition. The response represented in the illustration would most likely be caused by — A. B. C. D. A reduced supply of oxygen Long periods of rainfall High concentrations of glucose Little available water Label the structures and processes in the diagram below 10. 11. 12. 15. 14. 13.
