A) Both Assertion and reason are correct and reason is the correct explanation of the assertion. B) Both Assertion and reason are correct and reason is the not correct explanation of the assertion. C) Assertion is true but reason is false. D) Assertion is false but reason is true.

Answer 2

The correct option is A) Both Assertion and reason are correct and reason is the correct explanation of the assertion.

• If a system is separated from its surrounding environment by such a boundary that allows the transfer of materials or energy from and to the cell, then it is called an open system.
• In a cell, some nutrients are absorbed from outside while some are transported out of the cell. Similarly, energy can also be absorbed from outside by a cell. Waste materials are transferred out of the cell.
• Thus, the cell is an open system.
• The assertion statement states that the cell is an open system. While reason statement tells that cell receives materials and energy from outside. Thus, the reason statement correctly explains why the cell is an open system.
