Appearance of vegetative propagules from the nodes of plants such as sugarcane and ginger is mainly because:
1 Nodes are shorter than internodes
2 Nodes have meristematic cells
3 Nodes are located near the soil
4 Nodes have non-photosynthetic cells
Explanation:
Presence of meristematic cells gives the ability of vegetative propagation.

'Clones' are individuals that have exactly the same
1 Life span
2 Physiology
3 Growth rate
4 Genetic makeup
Explanation:
Clones are originated from a single parent which is completely genetically identical with the single parent body.

Grafting is impossible in monocots-because
1 Vascular bundles are scattered
2 Collateral open vascular bundle
3 Meristem is absent
4 Radial vascular bundle
Explanation:
Monocot plants cannot be grafted as they lack the cambium tissue, which is present in dicot plants. Cambium tissue is a meristematic tissue, which is present in the vascular bundles of the dicot plants. This tissue has a regeneration capacity due to which it can form new tissue at the time of grafting.
