The Casparian strip of plants is a specialized root structure. 15. Suppose your evil roommate creates a mutant basil plant that is lacking the Casparian strip. Which of the following is a likely phenotype ofthis mutant basil plant. A) Mis-regulation of stomata opening due to ion imbalance in the plant. B) Slower growth due to lower ATP levels in the root. C) Thicker sap due to higher solute concentration in the Xylem D) All of the above answers are correct. E) None of the potential answers are correct. 16. Suppose your evil roommate tries to poison you by watering your favorite basil plant with water that contains large quantities oflead (Pb. How would this affect your basil plant?

What is your advice?

Solution

15)D)alltheanswers are correct as all the options given will act as mutants

16)D)A AND B are true because lead diffuses into leaves through guard cells and roots both.

17)E_B,C AND D are true become pure water is not important for hydroponics as it swells the plant

18)E)The roots absorb CO2 from atomosphere to give it to soil as they get it from other animals and humans .
