This diagram covers Root Hair Cell Adaptations within Plant Transport Systems for GCSE Biology. Xylem and phloem structure, water and sugar transport, root hair adaptations, translocation, and practical investigations It is section 5 of 18 in this topic. Focus on the labels, the relationships between parts, and the explanation that turns the diagram into an exam-ready answer.
Root Hair Cell Adaptations
Root Hair Cell Adaptations Explained
- Large surface area: Root hair extension can increase surface area by 1000x, maximizing contact with soil water
- Thin cell walls: Allow easy passage of water by osmosis with minimal resistance
- No chloroplasts: Underground location means no light, so no photosynthesis needed
- Concentrated cytoplasm: Creates low water potential to drive osmosis from soil
Practice questions for Plant Transport Systems
Which substance does xylem tissue transport?
Explain how root hair cells are adapted for their function.
Quick recall flashcards
What is xylem tissue?
A plant tissue that transports water and mineral salts from the roots to the leaves.
What is phloem tissue?
A plant tissue that transports sugars and amino acids from the leaves to other parts of the plant.
