A major characteristic of monocot root is the presence of

A vasculature without cambium
B cambium sandwiched between phloem and xylem along the radius
C open vascular bundles
D scattered vascular bundles

Verified Solution

Answer & Solution

Correct Answer

(A) vasculature without cambium

Step-by-step Solution

Detailed explanation

(a) : In monocot root, a large number of vascular bundles are arranged in the form of a ring around the central pith. Vascular bundles are closed because there is no cambium present between the xylem and phloem.

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.

A point object is placed at a distance of \(60\, \mathrm{~cm}\) from a convex lens of focal length \(30 \,\mathrm{~cm}\). If a plane mirror were put perpendicular to the principal axis of the lens and at a distance of \(40\, \mathrm{~cm}\) from it, the final image would be formed at a distance of :
