What happens when carbohydrate is moved from a sink into a phloem sieve tube element?
- Awater potential in phloem sieve tube element becomes higher; volume of liquid in phloem sieve tube element decreases
- Bwater potential in phloem sieve tube element becomes higher; volume of liquid in phloem sieve tube element increases
- Cwater potential in phloem sieve tube element becomes lower; volume of liquid in phloem sieve tube element decreases
- Dwater potential in phloem sieve tube element becomes lower; volume of liquid in phloem sieve tube element increases
