Identify a pair of the following plants, which show modification of axillary buds into tendrils and hooks respectively
1 i, ii
2 ii, iii
3 iii, i
4 iv, i i. Hugonia ii. Duranta iii. Passiflora iv. Dioscorea
Explanation:
C Tendrils are a modification of stem as modified axillary bud in Passiflora. In some plants, terminal leaf lets are modified into curved hooks for helping the plant in climbing such structures are called hooks. Example -Hugonia. Tendrils are a thread like structures which helps the plant in climbing. - Duranta is a genus of flowering plants in the Verbena family. They are commonly cultivated as hedges and ornamental plants. - Dioscorea is a genus family Dioscoreaceae. The vast majority of the species are tropical, with only a few species extending into temperate climates.

Phylloclades are
1 green, photosynthetic, succulent stems of indefinite growth
2 one internode long stems
3 leaf modifications
4 none of the above

A Phylloclades are green photosynthetic, often succulent stems of indefinite growth. Phylloclade formation is an adaptation for xerophytes. eg. Opuntia, Casuarina etc. - Some plant groups instead have flattened green stem as the chief photosynthetic organs. These are called either cladodes or phylloclades.
