Which of the following causes enlargement and extension growth of cells?
Show answer & explanation
Correct answer: D
Explanation
The correct answer is option 4 i.e. Turgor pressure.
Turgor pressure is the primary cause of cell enlargement and extension growth:
-
Explanation
Turgor pressure is the positive pressure that builds up in plant cells when water enters them. This pressure pushes the cell membrane against the cell wall, causing the cell to enlarge and extend.
-
Other factors
In addition to turgor pressure, other factors that contribute to cell growth include:- Cell wall expansion: New cell wall materials are synthesized to allow for cell elongation.
- Hormonal regulation: Auxins and other hormones promote cell growth and elongation.
