- Q1Plant hormones serve as chemical messengers between cells and tissues. Auxin is a plant hormone that causes the cells on the shady side of a plant shoot to elongate. The response enabled by auxin is known as -phototropismgeotropismtranspirationphotosynthesis60sBIOL.10b
- Q2Copper 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?Copper that is absorbed by the roots is transported to reproductive tissues by the shoot systemThe shoot system transports copper to the roots after it is taken in through stomata in the leavesCopper is produced in the roots when copper-containing compounds are hydrolyzedThe shoot system stores copper for later use by the roots and the reproductive structures60sBIOL.10b
- Q3Some students are instructed to put a celery stalk in a red dye solution for a lab activity. First the students carefully cut the bottom of the stalk with a scalpel. Then they put the stalk in the beaker with the solution and place the beaker on a shelf in the lab room. The next day they check the stalk and make observations. The students note that the leaves at the end of the stalk have changed color from green to red. The students cut across the celery stalk and use a hand lens to see that the small tube openings along the edge of the celery stalk are also red. The cross section is shown below. How do the plant systems work together to make this movement of liquid possible?The roots lose water vapor to the soil, and the stem loses water vapor through the leaves.The roots absorb their own water and minerals, while the stem absorbs its water and minerals through the leaves.The roots anchor the plant in the soil, and the stem holds the leaves up.The roots absorb water and minerals and move them up to the stem, while the stem moves food produced in the leaves down to the roots in tiny tubes.60sBIOL.10b
- Q4The outermost layer of plant stems in dicotyledons consists of epidermal cells and guard cells that surround openings called stomata. The epidermal cells are usually covered with a waterproof layer that provides protection from injury and water loss. The stomata allow gas exchange. The epidermal cells and stomata have functions similar to those of which two human body systems?Cardiovascular and integumentaryIntegumentary and respiratoryCardiovascular and skeletalSkeletal and respiratory60sBIOL.10b
- Q5An animal can wound a tree by scratching away the bark. The tree can respond to the wound in many ways. Usually sap quickly covers the wound, and then the tree covers the wound with new growth. The diagram shows a cross section of a tree with a healed wound. What process worked most directly with the transport system to heal the wound?PhotosynthesisCellular reproductionWater intakeCarbohydrate storage60sBIOL.10b
- Q6Structures 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 -little available waterlong periods of rainfalla reduced supply of oxygenhigh concentrations of glucose60sBIOL.10b
- Q7The internal transport of water and minerals in plants requires that two systems work together. Which diagram correctly describes how the two systems accomplish this?60sBIOL.10b
- Q8The diagram shows the reproductive system of a plant. Which of the following best describes the interaction that occurs between a plant's reproductive parts during self-fertilization?Pollen is released from the stigma and is transferred to the anther. A pollen tube grows down from the anther through the filament and fuses with the ovule, where the sperm fertilizes the eggPollen moves from the ovule up through the style and is released from the stigma. The pollen is transferred to the anther, where the sperm fertilizes the eggPollen is released from the anther and is transferred to the stigma. A pollen tube forms and grows through the style. The pollen tube reaches an ovule within the ovary, where the sperm fertilizes the eggPollen is released from the anther and is transferred to the stigma. A pollen tube forms and grows through the style. The pollen tube reaches the filament, where the sperm fertilizes the egg60sBIOL.10b
- Q9Cytokinins are a class of plant hormones that help regulate growth by promoting cell division. Cytokinins are produced mainly in meristematic tissue, where most plant growth occurs. Which system carries cytokinins produced in the roots to the rest of the plant?None of theseVascular systemDermal systemReproductive system60sBIOL.10b
- Q10Several structures work together to allow flowering plants to reproduce. The diagram shows a typical flower. Which table correctly identifies the function of each structure or group of structures in the reproduction of the plant?60sBIOL.10b
- Q11Plants called sundews have rounded green leaves with many hair-like structures. The ends of these structures contain enzymes in a sticky liquid that looks like nectar or moisture, as shown in the picture. The hairs do not react to dust or nonliving material but will bend inward when insects get caught in the sticky liquid. Sundews digest trapped insects over a period of a few days. Based on this information, what functions do the specialized leaves of sundews perform?Provide nutrients to the plant and respond to stimuliRespond to stimuli and anchor the plantProvide water to the plant and perform photosynthesisRelease pollen to insects and perform photosynthesis60sBIOL.10b
- Q12Invasive plant species affect the interactions of living and nonliving components of an ecosystem, so the removal of invasive plants is often necessary. The goal of most plant-control methods is to disrupt or inhibit the function of different plant systems. For example, insects can be used to chew through roots in order to reduce a plant's ability to absorb water. Which of these functions would be most immediately affected by a reduction in water uptake by roots?Seed dispersalDisease resistancePhotosynthesisSunlight absorption60sBIOL.10b
- Q13A student reads this advertisement for a product containing a plant micronutrient that can be added to soil. Based on this information, the student can conclude that boron is absorbed by plant roots from soil and then -stored in plant stems until the flowers are pollinatedtransported by the phloem to the stomata in leaves, where it attracts pollinatorstransported to reproductive tissues by the plant's shoot systemconcentrated in the roots until the plant's reproductive tissues mature60sBIOL.10b
- Q14A student conducted an investigation to study phototropism in grasses. The only difference between the control group and the experimental group was light conditions. The control group was provided full light, while the experimental group was shaded on one side. The diagrams show the average heights and positions of blades of grass in the investigation. Which statement best explains why the grass tips of the experimental group bent toward the light?The xylem in the root system absorbed more nutrients from the shaded sideWater evaporated faster on the side of the plant having full lightThe side facing the light has a greater chance of absorbing carbon dioxide from the atmosphereLight sensors in the grass tips stimulated a hormone in the shoot system60sBIOL.10b
- Q15Plant roots have extensions called root hairs. These root hairs are important in the homeostasis of the plant. Which statement best explains the importance of the root hairs to the stems and leaves of the plant?Root hairs decrease the need for osmosis and diffusion in vascular tissue.Root hairs increase the surface area of the roots for nutrient and water absorption.Root hairs prevent water loss in leaves through transpiration and gas exchange.Root hairs convert minerals into glucose for immediate use by cells.60sBIOL.10b
