What is the difference between a vascular and a nonvascular plant? In your answer, discuss how water moves in each type of plant
Otrada [13]

Vascular plants have a vascular system while nonvascular plants have NO vascular system.

Explanation:

The vascular system is made of phloem – that transports food- and xylem- that transports water and minerals- in the higher plants. Examples of these higher plants are like trees and shrubs. These plants can take up water and nutrients from the soil and transport them up the plants to the leaves.

Lower plants have no vascular system (avascular). They mainly absorb food and water readily from their environment even through their leaves. This is why these plants are mainly found in humid areas like waterways, like canals. Examples of such lower plats are ferns and mosses.

Suppose we were successful in identifying 12 mutants using a screen for identifying conditional mutants of S. cerevisiae in whic
Marina CMI [18]

Answer:

Each mutant would be mated to wild type and to every other mutant to create diploid strains. The diploids would be assayed for growth at permissive and restrictive temperature. Diploids formed by mating a mutant to a wild type that can grow at restrictive temperatures identify the mutation as recessive. Only recessive mutations can be studied using complementation analysis. Diploids formed by mating two recessive mutants identify mutations in the same gene if the diploid cannot grow at restrictive temperature (non-complementation), and they identify mutations in different genes if the diploids can grow at restrictive temperature (complementation).

Explanation:

Recessive mutations are those whose phenotypic effects are only visible in homo-zygous individuals. Moreover, a complementation test is a genetic technique used to determine if two different mutations associated with a phenotype colocalize in the same <em>locus</em> (i.e., they are alleles of the same gene) or affect two different <em>loci</em>.  In diploid (2n) organisms, this test is performed by crossing two homo-zygous recessive mutants and then observing whether offspring have the wild-type phenotype. When two different recessive mutations localize in different <em>loci</em>, they can be considered as 'complementary' since the heterozygote condition may rescue the function lost in homo-zygous recessive mutants. In consequence, when two recessive mutations are combined in the same genetic background (i.e., in the same individual) and they produce the same phenotype, it is possible to determine that both mutations are alleles of the same gene/<em>locus</em>.
