As a result, the osmotic pressure in the tissue increases forcing the water to move through it. Phloem is a heterogeneous tissue composed of four different types of cells (sieve elements, companion cells. Phloem are the vascular Plant tissues. Xylem moves water from roots to the leaves, and phloem moves food from the leaves to the rest of the plant. a. transports food and nutrients b. transports water and minerals c. are made of dead cells d. is a type of ground tissue Phloem makes vascular bundles with xylem for mechanical strength. 29) The process of loading and transport of food through the phloem tissue involves which of the following factors? Phloem _____. Phloem transports food, while xylem transports water and dissolved minerals. • Source: Those organs or tissues where food is synthesized or available is known as source e.g. Main function of phloem is transport of food from source to sink. The flow of food and nutrients is bidirectional. It contains living tissues without a nucleus. The transportation of food in phloem is achieved by utilizing energy from ATP. Phloem is also important as the xylem tissues for the vascular system of plants. Phloem Definition. The transport of food from leaves to other parts of a plant is called translocation. Similarly mechanism of phloem transport can be understood by studying phloem anatomy. The main activity of this tissue is to transport nutrients and food from leaves to other growing parts of plants. Phloem Tissue. they are important for the vascular system. The term phloem is derived from the Greek word – φλοιός (phloios), meaning bark. Phloem parenchyma cells and phloem fibres) that are similar in origin and major function but differ in structure. Phloem. The phloem tissue in plants transports food materials from the leaves to different parts of the plant. • So phloem is a source for transportation. Transport in plants. • Sink: Those organs or tissues where food is utilized or stored are known as sink e.g. non-green parts of plant. Phloem is the complex tissue, which acts as a transport system for soluble organic compounds within vascular plants.. Phloem is present in all the parts of a plant. Unloading at the sink end of the phloem tube can occur either by diffusion, if the concentration of sucrose is lower at the sink than in the phloem, or by active transport, if the concentration of sucrose is higher at the sink than in the phloem. all of these are involved in phloem transport (osmosis, active transport, mass flow, osmotic pressure) Also Read: Transpiration Pull We will focus on the structure of phloem as well as how this vascular tissue actually transports food throughout a plant. They transport food and nutrients from leaves to the other growing and supporting parts of plants. seed, leaf etc. The food made by the leaves is in the form of simple sugar. Phloem Tissues.
