What does phloem carry up the stem
A
Sugar
B
Water
C
Oxygen
D
All of the above
Explanation: 

Detailed explanation-1: -Phloem (/ˈfloʊ. əm/, FLOH-əm) is the living tissue in vascular plants that transports the soluble organic compounds made during photosynthesis and known as photosynthates, in particular the sugar sucrose, to the rest of the plant.

Detailed explanation-2: -Plant Physiology and Development Phloem is one of the two tissues that make up the plant’s long-distance transport system, the other being xylem. Phloem translocates water and products of photosynthesis from source tissues to the sink regions where they are utilized or stored.

Detailed explanation-3: -The vascular system is comprised of two main types of tissue: the xylem and the phloem. The xylem distributes water and dissolved minerals upward through the plant, from the roots to the leaves. The phloem carries food downward from the leaves to the roots.

Detailed explanation-4: -Phloem, the vascular tissue responsible for transporting organic nutrients around the plant body, carries dissolved sugars from the leaves (their site of production) or storage sites to other parts of the plant that require nutrients.
