where do you find root hair cells?
close to the tips of growing roots, always relatively close to the xylem tissue.
1 of 12
what do the root hair cells do?
the root hair cell helps plants to take up water and mineral ions more effieciently.
2 of 12
how aare mineral ions moved into the root hair cell?
by active transport
3 of 12
what is the job of the xylem tissue?
it carries water and minerals up into the ret of the plant.
4 of 12
what are the three main adaptations of root hair cells?
•they greatly increase the surface area available for water to move into the cell.
• they have large permanent vacuole that speeds up the movement of water by osmosis from the soil across the root.
• they have many mitochondria that transfer the energy n

what are two of the adaptions of a photosynthetic cell?
• they contain chloroplasts that trap the light needed for photosynthesis.
• they have a permanent vacuole that helps keep rigid as a result of osmosis. (they also keep the leaf spread out so it can capture as much sunlight as possible).
6 of 12
what is another reason for xylem cells being so important?
they help in support the plant.
7 of 12
what are the two main way xylem cells are adapted to their functions?
• the cells have a special chemical (lignin) that builds in up in them over time and allows the cells to form long hollow tubes that let water and minerals flow from one end of the plant to another.
• the spiral rings of that chemical help them withstand

what is phloem?
phloem is the specialised transport tissue that carries the food made by photosynthesis around the plant.
9 of 12
What are the adaptations of phloem cells?
• The cell walls between the cells breakdown to form special sieve plates, which allow water carrying dissolved food to move freely up and down the tubes where its needed.
• these cells loose a lot of their structure so are supported by companion cells, t

what are the four specialised plant cells?
root hair cells, xylem cells, phloem cells and photosynthetic cells.

where may plant cells be specialised to function in?
within tissues, organs, organ systems, or whole organisms
