Show answer & explanation
Correct answer: C
Explanation
Correct Answer: Option 3: Tendrils
Explanation:
Plants with weak stems, such as peas, cannot stand upright. Therefore, they develop specialized, thread-like structures called tendrils. These tendrils are very sensitive to touch. As soon as they come into contact with a support (a fence or another plant), they wrap around it and provide support for the plant as it climbs.
Additional Facts:
Thorns: These are hard, pointed structures that protect plants (such as roses or lemons).
Root Hairs: These are found in roots and absorb water and minerals from the soil.
Cell Sap: This is the fluid inside the cell.
Types of Tendrils: In some plants, leaves develop into tendrils (such as peas), while in others, the stem itself becomes a tendril (such as grapes).
