Question
Listed below are a series of statements involving water transport in the roots 1 point of plants. Choose the four steps that are correct with regards to water transport in the roots of plants. Water enters the phloem tissue Water enters the xylem tissue Dissolved minerals, from the soil, move into the root hairs by the process of active transport. Dissolved minerals, from the soil, move into the root hairs by the process of diffusion. Water leaves the root hairs, by osmosis, to dilute the hypertonic solution. Water enters, by osmosis, into the root hairs to dilute the hypertonic solution. Water moves from the root hairs into, or between, cells farther in the root.

Answer
The correct steps for water transport in plant roots are:
1. Water enters the xylem tissue.
2. Dissolved minerals move into the root hairs by active transport.
3. Water enters the root hairs by osmosis to dilute the hypertonic solution.
4. Water moves from the root hairs into or between cells farther in the root.
These steps describe the accurate process of water and mineral absorption and transport within the root system.
Solution
The correct steps regarding water transport in the roots of plants are as follows:
1. **Water enters the xylem tissue.**
2. **Dissolved minerals from the soil move into the root hairs by the process of active transport.**
3. **Water enters, by osmosis, into the root hairs to dilute the hypertonic solution.**
4. **Water moves from the root hairs into, or between, cells farther in the root.**
**Explanation:**
1. **Water enters the xylem tissue:** After water is absorbed by the root hairs, it is transported into the xylem vessels, which are responsible for conducting water upward through the plant.
2. **Dissolved minerals, from the soil, move into the root hairs by the process of active transport:** Minerals often require active transport because they move against their concentration gradient, necessitating energy use by the plant cells.
3. **Water enters, by osmosis, into the root hairs to dilute the hypertonic solution:** The root hair cells have a higher solute concentration compared to the surrounding soil, causing water to enter the root hairs by osmosis to balance the solute levels.
4. **Water moves from the root hairs into, or between, cells farther in the root:** Once inside the root hair cells, water moves through the cortex either via the apoplast (between cells) or symplast (through cells) pathways towards the xylem.
**Incorrect Statements:**
- **Water enters the phloem tissue:** The phloem primarily transports sugars and other organic nutrients, not water.
- **Dissolved minerals move into the root hairs by diffusion:** Minerals typically require active transport, not passive diffusion.
- **Water leaves the root hairs by osmosis:** Actually, water enters the root hairs by osmosis to dilute the hypertonic solution.
**Selected Correct Steps:**
- Water enters the xylem tissue.
- Dissolved minerals, from the soil, move into the root hairs by active transport.
- Water enters, by osmosis, into the root hairs to dilute the hypertonic solution.
- Water moves from the root hairs into, or between, cells farther in the root.

Simplify this solution The Deep Dive
Water enters the xylem tissue is a true statement because xylem is responsible for transporting water and dissolved minerals from the roots to the leaves. Once water is absorbed by the root hairs, it travels through the xylem channels via capillary action and transpiration pull, ensuring that water reaches every part of the plant. Dissolved minerals, from the soil, move into the root hairs by the process of active transport is also correct. In this process, plants use energy to pump essential nutrients, such as potassium and nitrates, against the concentration gradient. This ensures that roots absorb the most vital minerals necessary for growth and development, empowering the plant to thrive in its environment.
