Theory:

There are two more categories of plants whose stems are weak and need support for their growth which includes Climbers and Creepers.
Climbers
Climbers have thin and weak stems and take support externally to climb and to stand upright, and to grow in the vertical direction.
They have tendrils (modified stem) which winds around the external support. Pea plants, money plant, beanstalk, gourd plants, grapevine are examples of climbers.

Creepers
Creepers have weak, fragile, thin stems which cannot stand upright, and thus spread or creep on the ground.
Pumpkin, watermelon, strawberries are examples of creepers.
