Correct option is A
The main functions of the stem are multifaceted and include:
- Support: The stem provides structural strength and support to the plant, allowing it to stand upright and grow towards sunlight.
- Transport: The stem acts as a conduit for water, minerals, and nutrients, facilitating their movement from the roots to other parts of the plant via the xylem and phloem.
- Food Storage and Production: In some plants, the stem stores food and may also assist in photosynthesis.
Thus, all three options (A, B, and C) are correct, making (a) the right answer.
