Phloem adaptations include companion cells providing energy, phloem vessel cells with reduced internal structures for efficient diffusion, and sieve plates allowing sugar transport.
Phloem adaptations include companion cells with mitochondria for energy, phloem vessel cells lacking nuclei and having limited cytoplasm for diffusion, and sieve plates with pores for sugar transport.
| Front | Describe and explain adaptations of phloem |
|---|---|
| Back | Mitochondria in the companion cell provide energy for the phloem vessel cells Phloem vessel cells have no nucleus and limited cytoplasm, to increase rate of diffusion End walls have pores called sieve plates, which allows allows the sugars to move through the cell interiors |
