- Has a circular, bioconcave shape which increases surfce area to volume ratio to release oxygen at a faster rate.
- Lacks nucleus which enables it to store more haemoglobin for transport of oxygen.
xylem vessels
- long hollow tubes extending from roots to leaves.
- Narrow and have no cross-walls to obstruct water flow through the lumen.
- Do not have protoplasm to offer resistance to water fow.
- Walls thickened with lignin to prevent it from collapsing.
