Study Notes
Xylem and Phloem Function
- Xylem transports water and mineral ions, providing structural support.
- Phloem transports sucrose and amino acids.
Xylem and Phloem Position (Dicots)
- Xylem and phloem are located in roots, stems, and leaves of non-woody dicots. Their arrangement varies in the different plant parts.
Root Hair Cells
- Root hair cells are specialized cells on the root surface.
- Their function is to absorb water and mineral ions from the soil.
Increased Water Uptake
- Root hairs have a large surface area, maximizing water and mineral ion absorption.
Water Pathway Through the Plant
- Water travels from root hair cells through root cortex cells into the xylem.
- Then, it moves through the xylem to the mesophyll cells of the leaves.
Transpiration Definition
- Transpiration is the loss of water vapor from leaves.
Effect of Environmental Factors on Transpiration Rate
- Transpiration rate is influenced by temperature and wind speed. Higher temperatures and stronger winds generally lead to faster transpiration.
