NEET · Biology · STD 11 - 6. Anatomy flowering plants

Given below are two statements:
Statement \(I\): Parenchyma is living but collenchyma is dead tissue.
Statement \(II\) : Gymnosperms lack xylem vessels but presence of xylem vessels is the characteristic of angiosperms.
In the light of the above statements, choose the correct answer from the options given below:

A Both Statement \(I\) and Statement \(II\) are false
B Statement \(I\) is true but Statement \(II\) is false
C Statement \(I\) is false but Statement \(II\) is true
D Both Statement \(I\) and Statement \(II\) are true

Verified Solution

Answer & Solution

Correct Answer

(C) Statement \(I\) is false but Statement \(II\) is true

Step-by-step Solution

Detailed explanation

Collenchyma is also living tissue.
Gymnosperm lack xylem vessels but presence of xylem vessels is the characteristic of angiosperm.

Apply the relevant identity from the chapter and substitute the values established in the previous step, keeping the original constraint in view.

Use the simplified expression to isolate the unknown, then plug the result back into the question setup to confirm the working is internally consistent.

Cross-check against a boundary or limiting case. Both the dimensional balance and the qualitative behaviour at the extreme should agree with the candidate answer.

Combine the steps above to identify the correct option. The remaining choices each fail at least one of the consistency, dimensional, or boundary checks.
