Question

Pandanus possesses
A. Stilt roots
B. Prop roots
C. Climbing roots
D. Tuberous roots

Answer 1

Hint: Pandanus needs additional support which is acquired by oblique adventitious roots which arise from the lower nodes of the ground. These roots are attached firmly into the soil and found in plants which grow near the river banks, ponds, etc.

Complete answer:
Stilt roots are the aerial, adventitious obliquely growing type of roots that develop from lower nodes of the stem to give additional support to the plant. These roots contain multiple root caps which are large overlapping root caps. E.g. is Pandanus, sugarcane, maize, etc.
Prop roots are adventitious roots in nature and are aerial roots also known as pillar roots. These thick aerial roots grow from horizontal branches and provide support like pillars. E.g. is Ficus bengalensis.
Climbing roots are the adventitious roots that arise from the nodes or internodes in plants having weak stems. Roots penetrate the cracks and help in climbing for support to the plant. For e.g. Pothos, vanilla, piper betel, etc.
Tuberous roots are the roots that store food in them in the form of tubers. These roots take up a lot of food from the soil and become thick and help in providing the food to the whole plant. These roots are also beneficial as they function as food reserves for the plant when the food is unavailable. For e.g. cassava.

Hence, the correct option is A. Stilt roots.

Note:
Basically, there are two types of root systems in plants which are tap root systems in which the roots have a central main root upon which roots are present. E.g. mustard, carrot, etc. Another system is fibrous root systems in which are bushy roots in which thin, moderate, branchy roots develop from the stem. E.g. rice, wheat, etc.
