Question

Which one of the following is correctly matched?
a. Passive transport of nutrients - ATP
b. Apoplast - Plasmodesmata
c. Potassium - Readily immobilization
d. Bakane of rice seedlings - F.Skoog

Answer 1

Active transport needs energy for the transport of molecules in the cells. Translocation occurs through the plasmodesmata. Bakanae disease affects the rice plant. Potassium is present in large quantities in the soils. Potassium is converted into soluble to insoluble form by immobilization.

Complete answer:
Cell membranes or plasma membranes are made up of proteins and lipids. Plasma membrane is a semi-permeable membrane it only allows the transport of some materials inside and outside from the cell. Transport of molecules throughout the membrane can occur by active transport and passive transport. Active transport needs energy while passive transport does not need energy for the transport of the molecules. Osmosis, diffusion and facilitated diffusion are used to transfer molecules throughout the membranes.

Immobilization is the process which is also called imprisonment of the cell. It is used for the conversion of inorganic compounds into organic compounds. Water soluble potassium is converted into water insoluble form. Bakane is also known as foolish seedling discovered by Shotaro Hori in 1898.

Apoplast is the system which includes cell wall and intercellular spaces in the root cells. It is called a non-living system. The transport of water occurs through apoplast.

From the above information we have found that potassium- readily mobilization or immobilization are related to each other.

Hence, the correct answer is option (C).

Note: Active transport requires ATP for the transport of materials through semi permeable membranes. Bakanae disease in the plants is caused by the fungus that is Gibberella fujikuroi. In the process of diffusion movement of molecules occurs from higher concentration to lower concentration. In the process of facilitated diffusion carrier proteins and channel proteins are involved.
