This tissue distributes sugars that leaves make during photosynthesis to the rest of the plant. These sugars are the plant’s food. And just like people can overeat, plants can make more sugars than they need at a certain time.

WebbThe cell cannot function without certain organelles and must rely on the organelles of the companion cells. The companion cell is responsible for all metabolic functions of the sieve tube member. The companion cell is essential for the survival of the sieve tube member. This will cause the member to cease phloem function and kill the plant.
