Please help with biology?

• 1. What is the primary function of the vascular system in plants? A) To transport water, mineral nutrients, and organic compounds to all parts of the plant B) To cover and protect the outside of plants C) To perform the processes of photosynthesis D) To transfer ions into the root 2. What vascular tissue carries the products of photosynthesis throughout the plant? A) Xylem B) Phloem C) Parenchyma D) Sclerenchyma 3. Which tissue is correctly paired with its function? A) Xylem: transports sugars B) Dermal tissue: stores materials in roots and stems C) Ground tissue: protection D) Xylem: transports water 4. Which plant tissue has a function similar to an animal’s skin? A) Dermal tissue B) Ground tissue C) Vascular tissue D) Plasmodesmata 5. Which statement regarding the pressure-flow model is NOT correct? A) It describes how sugar concentrations determine the direction of the fluid flow. B) It describes fluid flow from sources to sinks. C) It describes how transpiration occurs within the leaves. D) It accounts for the ability of sugar solutions to move up the plant as well as down the plant. 6. All of the following are functions of stems EXCEPT A) providing support for and elevation of leaves, flowers, and fruits. B) performing transpiration. C) transporting fluids between the roots and the shoots in the xylem and phloem. D) storing nutrients and producing new living tissue. 7. Which plant cells have the ability to divide throughout their lives? A) Collenchyma cells B) Sclerenchyma cells C) Ground cells D) Parenchyma cells 8. Which of the following is a function of roots? A) Transpiration B) Performing photosynthesis C) Providing support for leaves. D) Anchoring the plant to the ground 9. What does the cohesion-tension theory propose? A) Water is pulled upward in xylem when photosynthesis occurs. B) Hydrogen bonding in leaves pulls water up the stem. C) Water is pulled upward in the xylem due to differences in water potentials and pressures. D) Transpiration that takes place in the roots pulls water upward.
