Question

Which of the following is an incorrect statement?
A. Organisms grow with time
B. Organisms must repair and maintain their structure
C. Movement of molecules does not take place among cells
D. Energy is essential for life processes

Answer 1

Hint: The most important characteristic of an organism is the presence of protoplasm in the cells which facilitate the molecular movements among cells.

Complete answer: Molecular movements are those movements that are not visible from the naked eye but they are vital for the life processes.
They are the movement of molecules from one place to another and between the cells.
They are essential because cells are in constant need of the supply of basic commodities. Molecules move among cells through two mechanisms- active and passive transport.
Other processes such as osmosis and diffusion are important for the transport of various molecules such as the movement of water molecules to regulate stomatal closure.
Other processes such as growth and repair are required to sustain life.

Hence, the correct option is (C) Movement of molecules does not take place among cells.

Note: Molecules are in constant movement and the range of movement depends upon the conditions of the environment.
