The growth of tendril in pea plants is due to(a) effect of light(b) effect of gravity(c) rapid cell divisions in tendrillar cells that are away from thesupport(d) rapid cell divisions in tendrillar cells in contact with the support

Cell division in plants is promoted by

name the type of movement that occur within a plant cell

What is phototropism?Absorption of light energy by chlorophyllGrowth inhibited by lightGrowth stimulated by gravityGrowth stimulated by light2Which of the following statements correctly describes a plant’s response to gravity? Shoots and roots exhibit negative gravitropismShoots exhibit negative gravitropism, roots exhibit positive gravitropismShoots and roots exhibit positive gravitropismShoots exhibit positive gravitropism, roots exhibit negative gravitropism3What are the effects of the plant hormone auxin? Inhibits root and shoot growthInhibits root growth, stimulates shoot growthStimulates root and shoot growthStimulates root growth, inhibits shoot growth4When investigating the effect of light on seedling growth, which of the following is the independent variable?Number of seedsTemperatureDirection of lightDirection of growth5Which of the following best explains how the movement of auxin stimulates plant shoots to grow towards light directed at one side of the plant? Auxin is distributed evenly across the shoot, stimulating it to grow upwardsAuxin accumulates in the lit side of the shoot, stimulating the cells on this side to grow moreAuxin accumulates in the unlit side of the shoot, stimulating the cells on this side to grow moreAuxin accumulates in the unlit side of the shoot, suppressing growth of the cells on this side

ne of the traits that Mendel studied in pea plants is plant height. Tall plants are dominant with respect to dwarf plants. If the gene for this trait is denoted by the letter T, then the genotype of a dwarf pea plant is

In gravitropism, auxin affects the cells in shoots and roots in opposite ways. How are the two effects different?A.In stems, less auxin causes cells to shorten. In roots, more auxin causes cells to shorten.B.In stems, less auxin causes cells to strengthen. In roots, more auxin causes cells to strengthen.C.In stems, more auxin causes cells to grow wider. In roots, less auxin causes cells to grow wider.D.In stems, more auxin causes cells to grow longer. In roots, less auxin causes cells to grow longer.SUBMITarrow_backPREVIOUS
