Detailed explanation-1: -The phloem is composed of living tissue that actively transports sugars to plant organs such as the fruits, flowers, buds, and roots using turgor pressure and energy in the form of ATP. Translocation is the term for this movement process.
Detailed explanation-2: -In apoplast-loading species, sucrose reaches phloem parenchyma cells through plasmodesmata. Sucrose is loaded and accumulates in the phloem by passing through the apoplast between the PP and the CC.
Detailed explanation-3: -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-4: -phloem is the living tissue that transports the soluble organic compounds made during photosynthesis and known as photosynthates, in particular the sugar sucrose, to parts of the plant where needed. This transport process is called translocation.
Detailed explanation-5: -There has been a consensus in the phloem transport field for over 50 years that sucrose is the predominant sugar carried in the sieve tubes of most species.
