1. sugarcane, potato and ginger are ____.

(a) roots (b) stems (c) shrubs

Explanation:

Question 1

Plants are a source of food (e.g., fruits, vegetables, grains) and they are involved in processes that provide energy (like photosynthesis which is part of the food - energy chain for other organisms). Sunlight is not given by plants, and shelter is not the primary or typical dual output of plants in this context. So the correct option is (b).

Sugarcane has a stem (the cane part), potato is a tuber which is a modified stem, and ginger is a rhizome which is also a modified stem. They are not roots (roots have different structures and functions) and they are not shrubs (shrubs are a type of plant with a woody stem and specific growth habit, these are not shrubs). So the correct option is (b).

Baby plants (new plants) can grow from seeds (which are part of the plant's reproductive system) or from vegetative parts, but the option (a) "baby plants" is not a source, (b) "baby roots" is incorrect as roots don't produce baby plants in the way intended here. Stems can be a source of baby plants through vegetative propagation (e.g., potato tubers which are stems can grow new plants). So the correct option is (c).

Answer:

(b) food, energy
