D. Herbs

Answer 1

Hint: Grass belongs to family Poaceae. It includes the cereal grasses, natural grass land etc. The Poaceae are the most economically important plant family. Examples are: Maize, Wheat, Rice, Barley and Millet etc.

Complete Answer:
1) Climbers have soft stems and they need support from other plants or walls to climb. Climbers grow longer than grass.

2) Lianas too belong to climbers but the stem in lianas is woody. Lianas still need support from other plants to climb and reach to the top of the tree.

3) Corns, scientifically known as Zea Mays, is an example of Grass which belongs to the Poaceae family and shares the same features of grass.
- The stem is soft and green in color and performs the function of photosynthesis. Leaves have parallel venation and flowers are colorless.
- Wind pollination takes place in all the grasses including corn. Root shows fibrous root systems which are not too deep rooted.
- The suitable weather condition required for such plants to grow is a warm and humid atmosphere. Corns are taller than grass.

4) Herbs are soft stem plants which are very small and generally used in cooking and preparing herbal medicines.

The correct answer is “D”.

Note: Corn is a grass but certain grasses are also categorized as herbs. Grasses have hollow stems except at nodes and narrow alternate leaves. The leaf grows from the base of the blade, and adaptation allows it to cope with frequent grazing.
