How does root pressure primarily contribute to water transport in plants?
How does root pressure primarily contribute to water transport in plants?
- By actively transporting water molecules against a concentration gradient.
- By regulating the opening and closing of stomata to control water loss.
- By pushing water and minerals into the xylem of the roots, forming a water column. (correct)
- By creating a negative pressure that pulls water up the xylem.

If a plant's root pressure is significantly reduced due to a fungal infection, which process would be MOST directly affected?
- The photosynthetic activity in the mesophyll cells.
- The initial movement of water and minerals into the root xylem. (correct)
- The regulation of stomatal opening and closing.
- The rate of transpiration through the leaves.
Which of the following BEST describes the role of guard cells in transpiration?
Which of the following BEST describes the role of guard cells in transpiration?
- They directly pull water up from the roots to the leaves.
- They control the size of stomatal openings, regulating water vapor release. (correct)
- They facilitate the evaporation of water from the leaf surface.
- They protect the xylem vessels from collapsing under negative pressure.

Study Notes
- Transportation is the process of moving a synthesized or absorbed substance from one part of the body to another.
- Plants need inorganic substances like nitrogen, phosphorus, magnesium, manganese, sodium, etc.
- The richest source of these substances is soil.
- Plant roots absorb these substances from the soil and transport them.
- Xylem transports water.
- Phloem conducts food.
- All parts of the plant are connected with these conducting tissues.
