Stem may function for

Options

A. storage, support
B. protection
C. vegetative propagation
D. all the above

Answer

**Step-by-Step Text Solution:**

1. **Introduction to Stem Functions**: The stem is a crucial part of the plant that is primarily found above the ground. It serves multiple functions essential for the plant's growth and survival.

2. **Support**: One of the primary functions of the stem is to provide support. It holds the plant upright, anchoring it to the ground and allowing it to grow towards sunlight.

3. **Transportation**: The stem plays a vital role in the transportation of substances. It carries water and minerals absorbed by the roots up to the leaves and transports the food produced in the leaves to other parts of the plant.

4. **Storage**: Stems can also serve as storage organs. They store food in the form of starch and can be modified in some plants (especially in arid regions) to store water and nutrients.

5. **Vegetative Propagation**: Some stems are involved in vegetative propagation, allowing the plant to reproduce asexually. This includes the ability to produce new plants from parts of the stem.

6. **Protection**: The stem also has protective functions. It safeguards the vascular tissues (xylem and phloem) and can have modifications such as thorns to deter herbivores.

7. **Conclusion**: Based on the functions discussed, the stem is responsible for support, transportation, storage, vegetative propagation, and protection. Therefore, the correct answer to the question "Stem may function for" is "All of the above."
