Assertion: Multicellular organisms have a higher survival rate than unicellular organisms.
Reason: In multicellular organisms, dead cells are replaced by new cells.
Explanation:
Multicellular organisms and unicellular organisms are two different types of organisms based on their cellular structure. Multicellular organisms are composed of multiple cells that work together to perform various functions, while unicellular organisms consist of a single cell that carries out all necessary functions.
The assertion states that multicellular organisms have a higher survival rate than unicellular organisms. This is because multicellular organisms have a more complex structure and organization, which allows them to perform specialized functions and respond to changes in their environment more effectively.
The reason given for the assertion is that in multicellular organisms, dead cells are replaced by new cells. This process is known as cell regeneration or cell renewal. When cells in a multicellular organism die, new cells are produced through cell division to replace them. This continuous renewal of cells ensures the proper functioning and survival of the organism.
The reason provided supports the assertion because the ability to replace dead cells is an advantage for multicellular organisms. It allows them to maintain their structure and function, which in turn enhances their survival rate. Unicellular organisms, on the other hand, do not have the same mechanism for cell replacement. When a cell in a unicellular organism dies, the entire organism is affected, and there is no specialized mechanism for cell renewal.
Therefore, both the assertion and the reason are true, and the reason is the correct explanation for the assertion. Multicellular organisms have a higher survival rate due to their ability to replace dead cells with new ones.
