Which of the following does this chart represent?
promotes growth controls tropisms controls budding flowers
abscisis x
auxins x
cytokinins x
ethylene x
gibberallins x x

a the completed plant tissues and the cells that initiate their growth

b the relationship between different types of plant hormones and their functions

c the differences between plant structures and the hormones they produce

d the types of plant cells and their functions within the plant

Ans.

Plant hormones are signalling molecules, produced b plants that regulate growth, development and other cellular processes of plants. There are five types of plant hormones, which include abscisic acid, auxins, cytokinins, ethylene, and gibberallins.

Given chart represents relationship between different plant hormones and their responses or functions. Auxin promotes plant growth, plays role in tropism, abscisic acid plays role in seed and bud dormancy, cytokinin promotes cell division, ethylene controls plant growth and stimulates flowering, and gibberallins cause stem elongation.

Thus, the correct answer is option (B).
