Question:
Statement A: Shape of the cell is variable with the function they perform.
Statement B: Neuron cell is longest and branched animal cell that sends and receives signal from brain.
Statement A: Shape of the cell is variable with the function they perform.
Statement B: Neuron cell is longest and branched animal cell that sends and receives signal from brain.
Statement B: Neuron cell is longest and branched animal cell that sends and receives signal from brain.
Show Hint
Cell shapes vary according to their functions. Neurons are the longest and branched cells in animals, specialized for rapid signal transmission.

- A is false, B is true
- Both A and B are false
- A is true, B is false
- Both A and B are true
Show Solution
Verified By Collegedunia
The Correct Option is D
Solution and Explanation
Step 1: Understanding Statement A.
The statement mentions that the shape of cells varies depending on the function they perform.
- This is true because cells are specialized for different functions.
- Examples include:
- Red blood cells are biconcave discs to carry oxygen efficiently.
- Nerve cells (neurons) have long, branched axons to transmit signals.
- Muscle cells are elongated for contraction.
Hence, Statement A is true.
Step 2: Understanding Statement B.
The statement describes neuron cells:
- Neurons are specialized cells that transmit electrical impulses.
- They have dendrites (branches) to receive signals and axons to send signals.
- Some neurons, like the motor neurons, can be very long (up to a meter in humans).
This description is correct. Therefore, Statement B is also true.
Step 3: Conclusion.
Since both Statement A and Statement B are correct, the correct option is: Both A and B are true.
