Answer 1

Hint: The different parts of the plant are modified to absorb water, respiration, food storage, support, transport of water and minerals etc. These modifications perform major functions like physiological and mechanical.

Complete answer:
To solve this question, we must know about the different types of modification in plant parts.

Pneumatophores- These are the special aerial roots that help the plant in respiration in waterlogged soil. These roots develop from the stem or from the roots. These roots are lateral roots and grow upwards from the soil. These types of roots are found in mangroves. The correct match is (b)

Tendrils in pea- Tendrils in pea are the modification of leaf. These emerge from the leaf node. It is the terminal leaflet which is modified to tendrils. The correct match is (c)

Thorns in citrus- These are the modification of the buds which are present in the shoot. It is present in the axil of the leaf. The correct match is (a)

Hence, the correct answer is option (C)

Note: The axillary bud is also known as lateral buds. It is an embryonic shoot which is located in the axil of the leaf. These buds have the potential to develop into shoot. It acts like a vegetative shoot.
