What kind of substances are need to be transport in flowering plants?

Answer

**Step-by-Step Solution:**

1. **Identify the Types of Substances:**
In flowering plants, several types of substances need to be transported for their growth and survival. These include:
- Water
- Mineral nutrients
- Organic nutrients
- Plant growth regulators (phytohormones)

2. **Role of Water:**
Water is essential for various physiological processes in plants, including photosynthesis, nutrient transport, and maintaining turgor pressure. It is primarily transported through the xylem, which is a type of vascular tissue.

3. **Role of Mineral Nutrients:**
Mineral nutrients, such as nitrogen, phosphorus, and potassium, are vital for plant growth and development. They are absorbed from the soil and transported through the xylem along with water.

4. **Role of Organic Nutrients:**
Organic nutrients, mainly in the form of sugars produced during photosynthesis, are crucial for energy supply and growth. These nutrients are transported through the phloem, another type of vascular tissue.

5. **Role of Plant Growth Regulators:**
Plant growth regulators, also known as phytohormones, are chemicals that regulate various aspects of plant growth and development, such as cell division, elongation, and responses to environmental stimuli. These hormones are transported throughout the plant to coordinate growth.

6. **Summary of Transport Mechanisms:**
- **Xylem:** Transports water and mineral nutrients from the roots to other parts of the plant.
- **Phloem:** Transports organic nutrients (like sugars) from the leaves to other parts of the plant.

**Final Answer:**
In flowering plants, the substances that need to be transported include water, mineral nutrients, organic nutrients, and plant growth regulators.
