Question

The thing that is common between gourd, passion flower and grapevine is

• A. They all have roots modified to store food.
• B. They all have prop roots.
• C. They all have tendrils.
• D. They all have leaves modified as thorns.

Answer 1

Answer: (C)

They all have tendrils.

Climbers such as gourd, grapevine and passion flower have weak stem. Hence the stems of these plants develop threadlike structures called tendrils. Tendrils are aerial stem modification. When they come in contact with a solid support they coil around it and hence support these plants in climbing. They provide support to the plant. Thus the correct answer is 'They all have tendrils'.
