Stems contain chlorophyll and carry out photosynthesis in:

1. Opuntia and Euphorbia	2. Mint and Jasmine
3. Pistia and Eichhornia	4. Banana and Pineapple

A lateral branch arises from the base of the main axis and after growing aerially for some time arches downwards to touch the ground in:

Root hairs at the root tip are formed by:

In mango, the fruit is:

When sepals or petals in a whorl just touch one another at the margin, without overlapping, the aestivation is said to be:

Pneumatophores are found in plants growing in:

In papilionaceous aestivation:
1. standard overlaps the wings that overlap the keel
2. standard overlaps the keel that overlaps the wings
3. wings overlap the standard that overlaps the keel
4. keel overlaps the wings that overlap the standard

The lateral branches originate from the basal and underground portion of the main stem, grow horizontally beneath the soil and then come out obliquely upwards giving rise to leafy shoots in:

Stamens attached to the perianth as in the flowers of lily are called as:

Both stem tendrils and stem thorns:
1. help the plant to climb
2. develop from axillary buds
3. protect plants from browsing animals
4. can be used in vegetative propagation
