Question

Which one of the following is correctly matched?
a. Passive transport nutrients - ATP
b. Apoplast - Cell wall and intercellular spaces
c. Potassium - Readily immobilization
d. Bakane of rice seedling - F.Skoog

Answer 1

Active transport needs energy for the transport of molecules in the cells. Translocation occurs plasmodesmata. In root cells water is transported through apoplast. Bakanae disease affects the rice plant. Potassium is present in large quantities in the soils.

Complete answer:
Plasma membranes of the cell are made up of proteins and lipids. It is a semipermeable membrane. It only allows the transport of some materials. Passive transport does not need energy for the transport of molecules. Active transport needs energy for the transport of molecules. Carrier proteins play important in the transport of molecules throughout the membranes. Osmosis, diffusion and facilitated diffusion are used to transport molecules in the membrane.

Immoblisation involves the conversion of water soluble potassium into water insoluble form. This occurs to stop the transport of potassium in the membranes. Bakane is also known as foolish seedling. It was discovered by Shotaro Hori in 1898.

Apoplast is the system that is made up of cell walls and intercellular spaces in the root cells. It is a non living system. Transportation of most of the water occurs through apoplast.

From the above information we have found that apoplast and intercellular spaces are correctly matched.

Hence, the correct answer is option (B).

Note: Active transport requires energy ATP for the transport of the materials through semi permeable membranes. Bakanae disease in the rice 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.
