Concept explainers
Most of the growth of a plant body is the result of
- A. cell differentiation.
- B. cell division.
- C. morphogenesis.
- D. cell elongation.
Introduction:
Cell elongation is known as the developmental process of a plant. It allows the plant to grow and develop body parts of the plant. Cell elongation is regulated by phytohormones and light. It takes place in the meristematic region. Auxin, a plant hormone induces cell elongation in root hairs in a plant.
Answer to Problem 1TYU
Correct answer:
Most of the growth of a plant body is a result of cell elongation. Therefore, option (D) is correct.
Explanation of Solution
Reason for the correct statement:
Cell elongation occurs by the absorption of water through osmosis and vacuole formation. The cell elongation allows the plant to increase its root length and pushes the tip of the root forward that results in the growth of the plant body.
Option (D) is given as “cell elongation”.
As “the process of cell elongation involves most of the growth of a plant body”, it is the right answer.
Hence, the option (D) is correct.
Reason for the incorrect statements:
Option (A) is given as “cell differentiation”.
Many types of cells arise from their precursor cells by the process of cell differentiation. Cell differentiation is not responsible for the growth of the plant body. Hence, it is the wrong answer.
Option (B) is given as “cell division”.
Cell division is a process to form two genetically identical cells (somatic cells and germ cells). Cell division is responsible for the growth of the cells and not for the growth of the plant body. Hence, it is the wrong answer.
Option (C) is given as “morphogenesis”.
Morphogenesis involves the development of shapes and genesis in the plant. It is not responsible for the growth of the plant body. Hence, it is the wrong answer.
Hence, options (A), (B), and (C) are incorrect.
The cell elongation causes growth in the plant body by allowing osmosis and vacuole formation.

- magine that you are conducting research on fruit type and seed dispersal. You submitted a paper to a peer-reviewed journal that addresses the factors that impact fruit type and seed dispersal mechanisms in plants of Central America. The editor of the journal communicates that your paper may be published if you make ‘minor revisions’ to the document. Describe two characteristics that you would expect in seeds that are dispersed by the wind. Contrast this with what you would expect for seeds that are gathered, buried or eaten by animals, and explain why they are different.
