What two tissues transport materials throughout the entire plant body? A. sclerenchyma and xylem B. phloem and xylem C. parenchyma and xylem D. sclerenchyma and collenchyma E. epidermis and xylem _____are living cells that do not conduct sugar themselves but play a crucial role in assisting the movement of sugars. A. Sieve tube members B. Sieve plates C. Tracheids D. Vessel elements E. Companion cells Sugar is conducted in solution through specialized cells known as: A. fibers. B. companion cells. C. sieve tube elements. D. tracheids. E. vessels. High root pressure can cause water to be lost by leaves through the process of A) respiration B) regurgitation C) transpiration D) guttation E) translocation Which of the following terms would be used to explain how trees can lift water to heights of ten stories or more? A) air pressure B) adhesion C) cohesion D) tensile strength E) all of the aboveExplanation / Answer
Answer
18) option A is the right answer because Stomata is a cell covering small pore in the epidermis that facilitates the diffusion of carbon dioxide into herbaceous stem or leaves.
19) Option B is the right answer because phloem and xylem are the two tissue which is responsible for transport of material across the plant. Xylem is carrying water and minerals from the root to apex and phloem distributing the sugar and other material across the plant.
20) Option E is the right answer. Companion cells are living cells that do not conduct sugar themselves but play a crucial role in assisting the movement of sugar by supporting the cells of sieve elements.
21) option C the right answer because sieve element of phloem is responsible for conducting the sugar in the plants.
22) Option C the right answer because transpiration is the process in which plant loss the water by leaves.
23) Option C is the right answer because cohesion is the force acts within the same molecule in this case water molecule adhere with each other by the cohesion force which makes a huge water molecule( like water in straw) that help water travel up to the shoot.
