      are dead at functional maturity

      I do not understand this. Does this mean the Xylem stops working when the plant reaches maturity?

      plants have tissues that conduct food and water

      These plant tissues (vascular tissues) are also known as "TRACHEOPHYTES". These Vascular tissues are made up of two main tissues - The Xylem and Phloem.

      oxygen from photosynthesis

      Plants do not always carry "breathe'' out oxygen - sometimes they produce CO2. This is mostly at night as they need to break down carbohydrates to produce energy and also there is no sunlight during the night. With sunlight being one of the main components in the Photosynthesis process, plants cannot produce oxygen at night.
