The organic nutrients manufactured by plants are present in the

Options

A. flowers
B. xylem
C. barks
D. phloem

Answer

**Step-by-Step Solution:**

1. **Understanding the Question**: The question asks where the organic nutrients manufactured by plants are present. Organic nutrients refer to the food produced by plants through the process of photosynthesis.

2. **Photosynthesis Overview**: Plants are autotrophic organisms, meaning they can produce their own food. This process primarily occurs in the leaves where chlorophyll captures sunlight to convert carbon dioxide and water into glucose (a type of sugar).

3. **Transportation of Nutrients**: Once the organic nutrients (like glucose) are produced, they need to be transported throughout the plant. This is where the vascular tissues come into play.

4. **Identifying the Vascular Tissues**: There are two main types of vascular tissues in plants:
- **Xylem**: Responsible for transporting water and minerals from the roots to the rest of the plant.
- **Phloem**: Responsible for transporting organic nutrients (like sucrose) produced during photosynthesis from the leaves to other parts of the plant.

5. **Components of Phloem**: The phloem consists of several components, but the main ones involved in the transport of nutrients are:
- **Sieve Tubes (C-tubes)**: These are the main conduits for transporting sugars.
- **Companion Cells**: These cells assist the sieve tubes in the transport process.

6. **Conclusion**: The organic nutrients manufactured by plants are primarily present in the phloem, as this is the tissue responsible for their transportation throughout the plant.

**Final Answer**: The organic nutrients manufactured by plants are present in the phloem.
