Answer 1

Answer:

the correct statement is 1,2,3

Answer 2

Answer:

Statement 1) and Statement 4) are the correct statements.

Explanation:

Statement 1) is correct as it is true that minerals and the nutrients absorbed by the roots are transported to the upper areas such as the leaves and stems and growing regions.

Statement 2) is incorrect as it is not true that the nutrients in the senescence part of the plant get wasted and lost. The nutrients from the senescence part are transported to the other parts which are young and where minerals will be used.

Statement 3) is incorrect as half of the statement is correct when it states that there is complex traffic of the compounds in a flowering plant, but it is not in an unorderly manner. The movement is in an orderly manner in different directions.

Statement 4) is correct as all the hormones in plants show polarised or unidirectional movement.
