Question 16 1 / 1 point Cycads, Conifers (Gymnosperms) Flowering plants (Angiosperms) Club mosses (Non-vascular bryophytes) Ferns (Vascular seedless plants) Question 17 1 / 1 point the photo reactions the oxidation of glucose the synthesis reactions the synthesis of ATP Question 18 1 / 1 point Erosion increases when contour strip cropping is employed. reduces the top soil available for agricultural land occurs as a result of natural processes only causes accumulation of salinity in agricultural land Question 19 1 / 1 point Plasmolysis is the cytosol is the lipid membrane surrounding the cytosol causes the plasma membrane to separate and pull away from the cell wall. the breakage of the cell wall upon dehydration Question 20 1 / 1 point Which of the following options best describes the phloem? rigid, unliving, conducting tissue Living tissue with seive tube members and companion cells. Living tissue with tracheid cells Dead cells with companion cells for carbohydrate transport Question 21 1 / 1 point Both primary xylem and primary phloem are produced in the periderm cork cambium vascular cambium apical meristem Question 22 2 / 2 points The Cell Theory states that all cells contain DNA blueprints and structural support from lignin. that cells are part of all living and non-living things that cells may or may not arise from existing cells that cells are the basic organizational unit of living things Question 23 1 / 1 point In both G1 and G2 phases of the cell cycle, growth occurs DNA replication occurs the mitotic phase follows mitosis occurs simultaneously Question 24 1 / 1 point source; sink source; source sink; source or sink sink; source Question 25 1 / 1 point stomata perennial peridermal trichomes Question 26 2 / 2 points the quantity of usable energy declines with each energy transformation the quality of energy in the universe is constant energy can neither be created nor destroyed life should be impossible Question 27 1 / 1 point are proteins increase the rate of a reaction without being consumed by the reaction can make an energy requiring reaction energy yielding provide energy for the reactions they facilitate Question 28 1 / 1 point Plants use seeds, cones or spores to reproduce. Which of the following does NOT use spores? Conifers Mosses Ferns Liverworts Question 29 1 / 1 point Translocation is the process whereby water vapor is expelled from the leaf. False True Question 30 1 / 1 point The oxygen produced during photosynthesis is derived from . carbon dioxide glucose ATP water Question 31 1 / 1 point Which of the following statements about enzymes is FALSE? They consist of proteins. They change an energy requiring reaction to one that produces energy. They are highly specific They can be used over and over again. Question 32 2 / 2 points A hypothesis is: An outline of methods or approaches that could be used to test the validity of an idea An educated guess. The result of experimental evidence A question that can be tested Question 33 2 / 2 points The xylem–tension–cohesion theory explains how . water is transported in the xylem water is lost from leaf openings water and minerals enter the root leaf epidermal cells minimize water loss Question 34 1 / 1 point Vascular bundles are composed of xylem and phloem Question 35 True False 1 / 1 point Annual growth rings are the result of one year of secondary xylem Question 36 True False 1 / 1 point Which of the following is found in BOTH animal and plant cells? Mitochondria Lysosomes Chloroplasts Vacuoles Question 37 1 / 1 point Plants, Animals and Fungi all have this kind of cell: Prokaryotic Eukaryotic Primitive Fluid mosaic Question 38 1 / 1 point Dicots tend to have taproots. Question 39 True False 1 / 1 point Chromosomes do NOT participate in mitosis contain mostly lipids arranged like beads on a string organize the tangled mess of DNA inside the plant cell nucleus condense prior to mitosis Question 40 1 / 1 point Which of the following is NOT a function of the casparian strip? the casparian strip prevents water uptake through the apoplast (intracellular spaces) beyond the endodermis. the casparian strip borders the pericycle where lateral roots emerge. the casparian strip produces root hairs to improve the effective root surface area for water and mineral uptake100 the casparian strip prevents water from diffusing back out of the xylem to the roots. Question 41 0 / 1 point It decreases, because water exits and affects turgor pressure. There is no change; sugar concentration has no effect on turgor pressure. It decreases, because sugar concentration directly affects turgor pressure. It increases, because water enters and affects turgor pressure.
