A plant is kept in eosine for 3-4 hours. The pink color is likely to be seen in-

• A. Phloem tissue
• B. Cortex
• C. Xylem tissue
• D. Endodermis

Answer 1

The correct option is C

Xylem tissue

The correct option is C.

The explanation for the correct option:

1. The xylem of plants helps in the conduction of minerals and water throughout the plant. It is a vascular tissue of the plant.
2. When a plant will be dipped in eosine for 3-4 hours, the colored water will rise through the xylem.

Option A:

Phloem tissue helps in the conduction of food from the leaves to the roots, fruits, and seeds,

Option B:

The cortex is the external layer of the roots and stems in plants. It stores starch, provides nutrition through diffusion, and is water-proof.

Option D:

The endodermis helps in the selective regulation of substances that moves into the plant.

Final answer: A plant is kept in eosine for 3-4 hours. The pink color is likely to be seen in the xylem tissue.
