Phloem, also called bast, tissues in plants that conduct foods made in the leaves to all other parts of the plant. Phloem is composed of various specialized cells called sieve tubes, companion cells, phloem fibres, and phloem parenchyma cells.Click to see full answer. In respect to this, what is phloem and what is its function?Phloem is the vascular tissue responsible for the transport of sugars from source tissues (ex. photosynthetic leaf cells) to sink tissues (ex. non-photosynthetic root cells or developing flowers). Other molecules such as proteins and mRNAs are also transported throughout the plant via phloem. what is primary and secondary phloem? When plants photosynthesize, they convert sunlight into energy, and the phloem is what brings the nutrients downward to the roots. Primary phloem forms in primary growth regions at the tips of stems and roots, and secondary phloem is what arises from the vascular cambium. Secondly, what are the types of phloem? Types of phloem – definition The different elements of phloem include sieve tubes, companion cells, and phloem parenchyma and phloem fibres. Sieve tubes: Transport sugars and nutrients up and down the plants in sieve cells. Companion cells: Controls the activity of sieve tube.What is the other name of phloem? bast
