Question

Succulents can conserve $H_{2}O$ because

• A. The parenchyma is highly developed with large vacuoles.
• B. They have closed stomata during day and open at night.
• C. They have Crassulacean acid metabolisim.
• D. All of the above.

Answer 1

Answer: (D)

All of the above.

In botany, succulent plants, also known as succulents or sometimes fat plants, means plants having some parts that are more than normally thickened and fleshy, usually to retain water in arid climates or soil conditions. Succulent plants may store water in various structures, such as leaves and stems. Some definitions also include roots, so that geophytes that survive unfavorable periods by dying back to underground storage organs may be regarded as succulents. In these plants, the parenchyma is highly developed with large vacuoles. As a result, they have closed stomata during day and open at night. These plants are also called as CAM plants. Thus, option D is correct.
