Which of the following is not stem modification
1 Flattened structures of Opuntia
2 Pitcher of Nepenthes
3 Thorns of citrus
4 Tendrils of cucumber
Explanation:
B Pitcher of Nepenthes or pitcher plant is a modification of leaf not stem. It is a plant that is insectivorous. In this plant a pitcher like structure is transformed from a leaf lamina that traps insects. Pitcher plant showing lid and pitcher Stems of some plants are modified to perform different functions. Tendrils develop from axillary buds are spirally coiled and help plants to climb such as in cucumber. Opuntia, a plant grows in arid reasons modify their stem into flattened structure. In citrus fruits stems modified into pointed thorns to protect plants from grazing animals.

Which one of the following is correctly matched?
1 Chlamydomonas-Conidia
2 Yeast-Zoospores
3 Onion-Bulb
4 Ginger-sucker
Explanation:
: Onion propagate by bulb which is an underground, modified stem. A bulb consists of a relatively large, usually globe shaped, underground bud with fleshy overlapping leaves arising from a short stem. - Chlamydomonas is an algae and conidia are not found in algae. - Yeast and other ascomycetes characteristically produce ascospores. - Ginger propagates by rhizome not by sucker.

Tendrils are modifications of:
1 stem or leaf
2 stem only
3 leaf only
4 aerial roots only
Explanation:
A Tendrils may be modified leaves, leaflets, leaf tips or leaf stipules they may however, be derived as modified stem branches. They help in support and attachment by clasping, gripping near by objects. Example - grapes.

The modified stem of Opuntia is
1 phyllode
2 phylloclade
3 cladode

Explanation:
B The modified stem of opuntia is known as phylloclade. Opuntia is a xerophytic plant. Leaves are modified into spine, so the functions of photosynthesis is performed by stem which is thick, fleshy and flattened structures.
