Problem 151 - Objective Biology for NEET

Question

Assertion: Simple organism use special fluids within their bodies to transport materials. Reason: Boold is the only fluid used by higher organism including human for transport of certain substances.

Step-by-Step Solution

Answer

Both the assertion and reason are True, however the reason does not correctly explain the assertion.

Step 1: Evaluate the Assertion

Evaluate the assertion statement: 'Simple organism use special fluids within their bodies to transport materials.' This is generally true as many simple organisms use different types of fluids, like body fluid in amoeba, to transport various materials (like food and waste materials) within their bodies.

Step 2: Evaluate the Reason

Evaluate the reason statement: 'Blood is the only fluid used by higher organisms including human for transport of certain substances.' This is partially correct. While it is true that higher organisms like humans use blood for the transportation of certain substances (like nutrients, hormones, and oxygen), it isn't the 'only' fluid used. There are other fluids involved as well, such as lymph.

Step 3: Relate the Assertion and Reason

Next relate the assertion and the reason statements. Does the reason correctly explain the assertion? Considering the assertion speaks about 'simple' organisms and the reason about 'higher' organisms, these seem to discuss different levels of creature complexity and therefore, the reason does not correctly explain the assertion.
