2. What are companion cells?
- Living cells that connect phloem tissue together.
- Living cells found in phloem that support sieve tube elements by carrying out the living functions for them e.g. providing energy
- Dead cells that assist sieve tube elements by controlling what they do.
3. What is the SINK in transportation of solutes?
- The site where assimilates (solutes) are used up. e.g. roots
- The removal of ions from a plant.
- The site of production of assimilates (solutes). e.g. leaves
- The uptake of ions in the roots.
4. What are sieve tube elements?
- Living cells found in phloem that form the tube for transporting solutes. They have no nucleus and few organelles. They are supported by companion cells which carry out the living functions for sieve cells.
- Living cells that 'sieve' out what solutes are allowed through and those that aren't
- Dead cells that 'sieve' out what solutes are allowed through and those that aren't
5. What is the symplast pathway?
- Movement of water through the vacuole.
- Movement of water through the cytoplasm through the plasma membrane. The cytoplasm of cells is connected through plasmodesmata.
- Movement of water through cell walls, allowing mineral ions and salts to be carried with the water.
