Which of the following mechanisms is responsible for providing support in plants?
A.
Muscles and bones
B.
Exoskeleton
C.
Endocrine system
D.
Cell walls and turgor pressure
Correct answer is D
The mechanism responsible for providing support in plants is the combination of cell walls and turgor pressure. In plants, the cell walls, composed of cellulose, provide structural support to the cells and tissues. They give rigidity and strength to plant cells, enabling them to maintain their shape and resist external forces. Additionally, turgor pressure, which is the pressure exerted by the cell contents against the cell walls, helps maintain the overall rigidity and upright form of plants.
