$\begin{array}{cc}\text{a. Leaf}& \text{i. Pollination}\\ \text{b. Stem}& \text{ii. Water absorption}\\ \text{c. Root}& \text{iii. Nutrient translocation}\\ \text{d. Flower}& \text{iv. Transpiration}\end{array}$

• A. a-i, b-ii, c-iii, d-iv
• B. a. iv, b-iii, c-ii, d-i
• C. a. iv, b-iii, c-i, d-ii
• D. a. iv, b-i, c-iii, d-ii

Answer 1

The correct option is B a. iv, b-iii, c-ii, d-i

Just like us, plants also have different body parts: roots, stem, leaves, flowers, fruits.

1. Attachment of the roots to the soil help to fix the plant tightly to the soil. The roots of the plants help in absorption of water and minerals from the soil.
2. Stems of the plant also help in translocation of water and food materials. However, in some plants, stems adapt themselves for storing food as well.
3. Key role of the leaves are: Transpiration and Photosynthesis. Stomata present in the leaves plays a key role in the exchange of gases between the plant and atmosphere through transpiration. Another leaf function is the preparation of food for the plant by the process of photosynthesis.
4. Flowers have colourful petals and they attract insects and birds that help with pollination.
