The underground stem that has contractile roots is:
1 Rhizome
2 Corm
3 Stem tuber
4 Bulb
Explanation:
BCorm- It is a condensed structure which grows vertically under the soil surface. They possess spherical node and internodes and they possess contractile roots. Ex- Colocasia, Alocasia, a) Rhizome- It is a fleshy and horizontal stem found under the soil. Small nodes and internodes are found which are covered with scaly leaves. Ex- Ginger, Turmeric, Canna, Water lily and Banana. c) Stem tuber- The tip of underground branches become swollen in the soil. Eyes are found on them which are axillary buds and they are covered with scaly leaves. Ex- Potato. d) Bulb- The stem is reduced and has a disc like structure which surrounds with numerous fleshy scaly leaves. Many roots arise from its base and food is stored in their fleshy leaves. They show apical growth. ExOnion and Garlic.

5 Subaerially growing stems in grasses and strawberry help in vegetative propagation Choose the correct answer from the options given below :
Explanation:
D Axillary buds of stems get modified into woody straight and pointed thorns. Thorns are found in many plants such as citrus and bougainvillea. - Axillary buds form slender and spirally coiled tendrils in cucumber and pumpkin, in these plants the tendrils help in climbing and provide support. - Stem is flattened and fleshy in Opuntia and modified to perform the function of leaves, the stem is modified to carry out photosynthesis due to the absence of leaves. - Rhizophora shows vertically upward growing roots that help to get oxygen for respiration, these roots are called pneumatophores. - Subaerially growing stems in grasses and strawberry help in vegetative propagation, these stem are called stolons and can form new plants when they touch the
