Question

In submerged hydrophytes, the stems are extremely weak due to

• A. Absence of phloem
• B. Absence of xylem
• C. Presence of aerenchyma
• D. Poor development of xylem and mechanical tissue

Answer 1

The correct option is D Poor development of xylem and mechanical tissue

In submerged hydrophytes, the entire plant body is involved in the absorption of water and these plants not experiences much stress or pressure internally. So in these plants, xylem and mechanical tissues are poorly developed.

So, the correct option is ‘Poor development of xylem and mechanical tissues’.
